Wide variety of accessories available, including our SHUNT100 , second antenna arm (AMB_Arm2 ) and many others (listed below). Available in buffed aluminum or powder coated finishes. In addition to many other uses, these are a great way to mount EMCOMM antennas or antennas in restricted neighborhoods - powder coat finish may even blend in with your mounting surface! Unlike some portable mounts, we include provisions for the very necessary ground counterpoise, using wire or telescoping radials, to radiate your signal and not "just heat up the clouds". CLAMP-150: "clamp-to-anything" mount for fixed-base, travel, QRP, EMCOMM, and portable antenna systems that will support mobile HF/V/UHF antennas up to medium sized HF screwdriver/motorized antennas. Will fit essentially any flat surface, vertical, horizontal AND tilted, that is up to 9 inches THICK - yes, 9 inches! It is installed and removed in only a couple minutes. Comes with your choice of antenna base. Options include counterpoise "rings" and the "Arm2" - see below. Makes a great, small and light, addition to your "go bag" (this is N7EMW's main travel antenna mount).THERE IS NOT OTHER CLAMP MOUNT THAT CAN DO THIS!   CLAMP-150-W: NEW version of the CLAMP150 for mounting a WiFi panel antenna to connect to your remote internet router (I tried this while staying at a lodge where their router antenna was too far away to be picked up by the internal WiFi antenna in my laptop from our room).   CLAMP-200: heavy-duty clamp-on mount for RV and building ladders, open railings and some open fences. Designed to be mounted vertically on ladders or horizontally with an optional adapter bracket. Will support even large HF screwdriver/motorized antennas.

CLAMP-150: Clamp To Anything Portable HF/V/UHF Antenna Mount NOTHING ELSE ON THE PLANET IS LIKE THE CLAMP-150 ==> for travel, QRP, EMCOMM, antenna restricted areas, portable and fixed-base mobile HF/V/UHF antenna setups! Folks, the CLAMP150©  is a REALLY UNIQUE way to mount 1 or 2 (with optional arm) mobile antennas at a QRP, fixed-base or portable antenna location, where you have almost any flat surface that will support your antenna! You don't need a tripod or mast! This may be just the solution for travel antennas, QRP, antenna restricted neighborhoods and EMCOMM. It's small and light weight (only 3.5 lb. including the larger optional AMB-Gnd-8  counterpoise ring), and quickly dissassembles to approximately 6 inches x 15 inches - fits in small suitcases and "go bags". Best of all, you can work DX at QRP power levels! The CLAMP150 is the main mount in N7EMW's "go bag", and was oringinally designed for Dick's travel/QRP antennas after many different antenna mounting schemes were tried over many years. He's used tripods, masts and various ways to "duct tape" antennas to railings and whatever is available to support an antenna. The outcome of Dick's many mounting schemes and tests has resulted in the CLAMP150! Using the CLAMP-150 mounted to railings and benches, N7EMW has work DX with 5 watts on battery power. The CLAMP150 quickly clamps to almost any VERTICAL, SLANTED and HORIZONTAL flat surface from 1/2 inch to 9 inches thick (yes, 9 inches!). The antenna can be rotated to accomodate various surfaces and if you want to tilt the antenna, such as to clear the roof gutter when mounted to a deck railing. No other portable antenna mount can attach to such a wide variety of surfaces! This continues our philosophy of designing and manufacturing truly unique one-of-a-kind products. As with all of our products, the CLAMP is blueprinted and replacement parts are available. The CLAMP can be mounted in a couple of minutes, without tools (for larger antennas you should tighten the wing nuts with a plyers). Wing nuts are provided on both ends for quick installation and removal for your portable antenna setup. The CLAMP150 comes with YOUR CHOICE of three interchangeable antenna bases to support just about any mobile antenna up to medium size HF screwdriver/motorized antenna: 3/8x24 stud, NMO and SO239 ("UHF") bases - all with an SO239 connector for your PL259 coax plug! The CLAMP comes with your choice of connector and you can order a second base or all three, since all bolt into a 3/4" hole with the provided hardware and heavy-duty nuts. We even offer an NMO base with four REMOVABLE (e.g. portable) groundplane radials for 135-512 MHZ (NMO radial base ) - mounted on the CLAMP150 or on the optional second antenna arm (AMB_Arm2 ). Read below about the different accessories and options that are available. The CLAMP is made of 6061 and 6063 aluminum with 18-8 stainless steel hardware. It comes in buffed aluminum and optional powder coated finishes (5 colors). The "clamping surfaces" have a weather and wear resistant EDPM rubber layer to provide maximum grip while protecting the clamping surface. Every detailed is considered! It also has TWO (2) ground locations and optional "ground coujterpoise rings" (AMB-Gnd-1, AMB-Gnd-8 ) also can be used - a ground counterpoise is critical for good RF performance. Also available is an NMO with a V/UHF groundplane! Attention to detail! Here are some of the horizontal, slanted and vertical mounting surfaces that the CLAMP-150 can be clamped to for supporting an antenna up to a medium sized HF antenna, even many HF screwdriver / motorized antennas, assuming the surface you mount the CLAMP-150 to can support the antenna: metal and wood deck railings - clamps vertically to post or horizontally to top railing fences - wood, metal, split rail, etc. deck and park benches chairs (if they do not tip over!) lifeguard stands - what a DX location! canoes, kyaks and other boats (the optional powder coat finishes offer salt water protection) glass tables....as long as you're careful! almost any table.....picknic bench or your dining table for "inside DX" highway guard rails you name the surface - how about a "worked all surfaces" contest??? Any "radio backpackers" out there who want to try "portable surfaces" DX?? The "CLAMP" will fit the following types of antennas, RIGHT FROM THE BOX, with the appropriate base (3/8x24, NMO or SO239 ("UHF") - your choice or get all three bases as they are interchangeable): small to largest V/UHF mobile antenna (6m and above) HF "ham stick" type antennas  HF HustlerTM and Texas Bug CatcherTM loading coil type antennas OutbackerTM "clip-lead" type antennas manually tuneable HF antennas such as: Super Antennas MP-1 MFJ-1624 HF mini-BugCatcher Mobile Antenna MFJ's various models of 6 Thru 40 Meter Portable Screwdriver Antennas and others small to medium HF motorized / screwdriver antennas such as: smaller (up to 3 and 4 series) Hi Q Antennas motorized HF antennas - I even tested it with my LARGE Hi Q Antennas RT-5/160 with a 10 ft. whip and four 10-12 ft. telescoping whips as the ground counterpoise - fully supported the antenna on my deck (see photo below)! High Sierra "Sidekick" and the larger HS1500, HS1800 models if your surface can support the antenna Tarheel "Little Tarheel"; one customer is using his full-size Tarheel Model 100 on his deck with the CLAMP150!  Super Antennas MP-2 and others  Here's WHAT YOU NEED to set up your antenna on the CLAMP150: flat surface to attach the CLAMP that will support your antenna and counterpoise safely (see above list of mounting surfaces) your antenna (see above list, majority of HF, V/UHF mobile antennas acceptable) antenna screws directly into the base provided with the CLAMP (your choice of base or get all three) - no insulating washers needed use whatever whip you want on top of your antenna if required (e.g. screwdriver antenna) your coax - standard PL259 plug connects directly into the base of all of our antenna bases ground counterpoise standard: CLAMP150 has two ground points with HD solder lugs (accept 16-12 gauge wire) - connect four or more at least 10 ft. long or 1/4 wavelength inexpensive stranded hookup wire soldered to the provided solder lugs optional: our telescoping whip ground counterpoise "ring" brackets (AMB-Gnd-1, AMB-Gnd-8 ) - screw on your whips with standard 3/8x24 stud, telescoping or not, any length (MFJ and Buddipole, for example, provide telescoging whips up to 12 ft. long - see LINKS  page); use "tuned" HF antennas such as "ham sticks" that can provide improved performance on the mid and low bands by having a tuned counterpoise. I've found that at least four, 10-12ft. telescoping whips, make a reasonable counterpoise on 20m and above and have worked DX using 5 watts on battery power with such a counterpoise! SWR matching device if required for HF antennas tuning 160-40m ( low band antennas mounted near the ground) wind your own coil (dimensions not critical but must tune for low SWR first on the lowest band) our SHUNT100  weather proof and easy to tune with clip our "Parts-Coil-01" coil/clip (heart of the SHUNT100 without the weatherproof housing/bracket) UNUN switchable matching device your radio.....and that DX station you want to work Right from the box the CLAMP150 can be used WITHOUT any options to support the antennas on the mounting surfaces, as mentioned above.

Here's the story about how the CLAMP-150 W came to be. My wife and I travel once in a while (always of course with my portable HF/V/UHF station and a laptop) and sometimes I've been unable to connect to our hotel's WiFi router if our room is a ways away from their internet router - we sometimes stay in cottages away from the hotel office. Here's a solution I came up with to mount my panel WiFi antenna, and I realized that the CLAMP-150, with the addition of a third "L" bracket, allows you 3 dimensional rotation of a panel antenna - vertical and horizontal polarization! To this I added a higher power USB WiFi adapter with an external antenna jack. I mounted the higher power WiFi adapter on the panel antenna with a very short coax for low loss, and used a longer USB cable to run from the adapter/antenna to my laptop. While on Cape Cod, MA, I was able to detect WiFi routers located across an ocean bay, line of sight, over 3 miles away! If you're interested in more details about my WiFi setup, please CONTACT US . I can provide a WiFi antenna, a higher power USB adapter and connecting cables as a "complete system", or tell you where you can purchase them directly. Everything I used is legal in the US and readily available from internet specialty stores. Product Photos and Videos: The following are just a few of the photos that we have on our products, to illustrate some of the key features and installation ideas for this item. PHOTO BELOW: CLAMP-150-W prototype with panel WiFi antenna and higher power WiFi USB adapter (the small "black box"). The town in the distance is over 3 miles away, yet I was able to detect over 20 routers. JUST REMEMBER YOU CANNOT connect to routers without the owner's permission!  PHOTO BELOW: Laptop screen showing all of the WiFi signals I was "DXing" during my first tests, using the setup in the above photo. WIth this same antenna and adapter I was able to connect to our hotel's router located in their office across a main road and hundreds of feet away from our building - without this I could not connect reliably with my laptops internal WiFi radio.  PHOTOS BELOW: The production version of the CLAMP-150. Please note that it does NOT come with any WiFi antenna (shown) or coax. ORDER HERE: CLAMP-150W -- please CONTACT US  for a price. This is a new product that is now available by special order. It can also be powder coated. As stated above, I can also provide a complete WiFi antenna system and USB adapter, with all cables, that simply plugs into any PC or PC laptop with a USB2.0 connector (or provide information on where you can directly purchase the items seperately).   CLAMP-200: HD Clamp-On Mount for Ladders and Fences   NOTHING ELSE ON THE PLANET IS LIKE THE CLAMP-200! The CLAMP-200© (“CLAMP”) is a heavy-duty "clamp-on" base that, with the appropriate mount or bracket, can be used with essentially any amateur HF/V/UHF, CB and commercial mobile antennas, and even with antenna masts and flag poles up to 2 inches in diameter. It can be used for temporary or permanent fixed-base installations. It  attaches to RV ladders (even while driving) and building ladders, railings and some fences. It has three bolts that "clamp" the two heavy-duty halves together through your mounting surface - NO DRILLING REQUIRED! The thickness of the mounting surface can be up to 3 inches (standard) or up to 7 inches thick with optional longer mounting bolts - enough for most if not all ladders and railings. This may be just the solution for your small to large HF/V/UHF mobile antenna setups, and can be moved from one configuration to another: Fixed-base vacation spot where you want to install your mobile antenna to a ladder or railing, and to some fences. The CLAMP is quickly installed and removed for temporary installations. Recreational Vehicle (RV) ladders - VERY sturdy base for mounting even a large HF screwdriver or motorized antenna, and if the antenna is not too tall, the CLAMP-200 can be left on WHILE DRIVING with the appropriate antenna bracket! Just be sure that your ladder can support your antenna. We even include a couple of options for an effective ground counterpoise, which is necessary on fiberglass vehicles for all HF and most V/UHF antennas. If the antenna is too long to drive with, remove the antenna but leave the CLAMP-200 installed. Deed restricted neighborhoods - where you need  a STURDY base for an "invisible" antenna system and want provisions for a decent ground counterpoise that is not simply a "wire strung on the ground". The CLAMP can be installed permanently. EMCOMM - if your radio trailer or vehicle does not have space for "another antenna" you can quickly install the CLAMP on a ladder, railing and some fences.  Use the CLAMP instead of a tripod which may blow over in a strong winds! QRP to full power. Light-weight antenna masts and flag poles with an O.D. of 1-2 inches. Mounts vertically or horizontally - we have brackets for almost all mobile antennas that simply bolt to the CLAMP-200 base. Provides connection points for ground counter poise - wire type or use telescoping whips with optional brackets. The CLAMP-200 and optional antenna mounting brackets are made of 6061 aluminum with 18-8 stainless steel hardware. The outer "clamping surface" has a weather and wear resistant EDPM rubber layer to provide maximum grip. The inner clamping surface is bare aluminum to "ground" to metal surfaces. The CLAMP200 and the optional brackets and mounts come standard in brushed aluminum, and also optional powder coat finishes. Every detailed is considered!

The UHAM200 will mount directly the the AMB-HMA-1 with provided hardware, as with all of our antenna mounts and brackets.     Ground counterpoise brackets - NOT REQUIRED if you use a simple wire ground counterpoise (wire counterpoise radials connect to the provided ground points on the CLAMP and antenna brackets). AMB-Gnd-1 or AMB-Gnd-8:  Ground counterpoise "ring" bracket for using four of your telescoping whip or CB whip antennas that have the standard 3/8x24 thread. Simply bolts to a HORIZONTAL CLAMP (only). Can be used in place of a simple wire ground counterpoise connected to the CLAMP bracket ground points.   AMB-Gnd-2  : Three (3) sets of hardware for three of your telescoping whip or CB whip antennas that have the standard 3/8x24 thread. Simply bolts to a VERTICAL CLAMP (only). Can be used in place of a simple wire ground counterpoise that the user can connect to the CLAMP ground points. Other options  - NOT REQUIRED, that may be useful for your antenna system. AMB-Arm2 : Second antenna bracket for mobile V/UHF antennas, with NMO base and four removable ground radials for 135-512 MHz. Bolts to antenna brackets AMB-Bkt-1 and AMB-Bkt-1T mounted on vertically or horizontally installed CLAMP (will not fit UHAM200). SHUNT-100 : Adjustable weather resistant shunt load inductor for those installations that have a low impedance on the low bands (160-40m) resulting in a high SWR, especially for antennas mounted near the ground. This is for antennas that need additional inductance (another type of device is needed for antennas that require additional capacitance). Includes a silver plated coil clip with tightening screw and tin plated solid copper coil. Simply bolts to ANY of our CLAMP antenna brackets listed above, including UHAM200. The coil and clip used in the SHUNT-100 are also available for purchase without the SHUNT case ("Parts_Coil-01 ", shown in right photo).   ANTENNA BASES : We provide heavy duty 3/8x24 stud, SO239 and NMO bases, all of which fit into the standard 3/4 inch hole on our brackets and plug dirrectly into your coax PL259 plug. They can also mount into 5/8 inch diameter holes (3/8 stud mount mounts only into a 3/4 inch hole) - we provide stainless steel washers to accomodate the 3/4 inch holes. They include heavy-duty nuts. All are interchangeable on our brackets and are quickly removed or installed. Long bolt kit allows mounting the CLAMP-200 to surfaces up to 7 inches thick (standard bolts work up to 3 inches thick).
