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!

Here's WHAT YOU NEED to set up your one antenna system with the CLAMP200

  • surface to attach the CLAMP that will support your antenna and counterpoise safely (see above list of mounting surfaces above) - ladder, railing, etc. - up to 3 inches thick (up to 7 inches thick with our optional LONG BOLT kit)
  • antenna mount and bracket for attaching your antenna(s) to the CLAMP200 HD base - depends on whether the CLAMP200 is mounted vertically or horizontally (see below).
  • your antenna (see above list)
    • we offer a wide range of mounts, antenna bases and brackest for different types of antennas (see below)
  • your coax - plugs into our optional antenna bases
  • ground counterpoise
    • standard: ground point with HD solder lug (accepts 16-12 gauge wire) provided with the CLAMP200 - your inexpensive stranded wire soldered to the solder lug (four or more lengths each at least 10 ft. long or 1/4 wave length)
    • optional ground counterpoise brackets for your telescoping whips with 3/8x24 threads (see below
  • SWR matching device for HF antennas tuning 160-80m - adding inductance for antennas near the ground
    • wind your own coil (dimensions not critical but must tune for low band)
    • our SHUNT100  weather proof adjustable HF load inductor
    • 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

The CLAMP200 provides a very sturdy base to which you mount the type of antenna mount or bracket that you need for your antenna(s) and whether you mount the CLAMP200 vertically, such as on a ladder, or horizontally, such as on a railing.  The various options are listed for the vertical and horizontal configurations - whatever mobile antenna you need to mount, the CLAMP200 can likely meet your needs!

All CLAMP-200's are drilled to fit all of our options and, along with all of our options, are blue printed. The following options simply bolt to the CLAMP with provided hardware. We also provide replacement parts (contact us for information).

The CLAMP200 can be ordered below, after the "Accessories and Options" and "Photos" sections.

Accessories & Options:

Here's the list of required mounts/brackets and options for the CLAMP200 that you can use for your specific antenna setup - for vertical and horizontal configuations.These can be ordered by clicking on the PRODUCT NAMES below, which take you to a detailed description and ordering page for each item. We offer a discount if you order three (3) or more of one or multiple products.

The following picture shows the vertical and horizontal mounting dimensions and concept behind these configurations. If your situation meets these dimenstions, the CLAMP200 will fit!

 

(A)  CLAMP200 VERTICAL MOUNTING: Required and Optional Items

The following pictures illustrate a vertically mounted CLAMP200 and how the various options are mounted.

   

The vertical CLAMP200 configuration works on RV and building ladders, and on wood and metal railings that have horizontal rungs with openings for the three "clamping" bolts. The following are required or optional for vertically mount CLAMP200s. At a minimum, you need one antenna mount but nothing else.

  • Antenna & Mast Brackets - one bracket is REQUIRED for a vertically mounted CLAMP200 - get more than one if you have different antennas - they easily unbolt and install. Our Product Guide  may also be useful in selecting the antenna mount/bracket for your specific needs, as it lists all of our products and the types of antennas that are compatible. If you are are not sure or need any help, please CONTACT US for a friendly and fast response.
    • AMB-BKT-1 : Standard "L" bracket (4x4 x 2" wide x 1/4 " thick) that will fit essentially any HF/V/UHF antenna up to a small/medium screwdriver / motorized HF antennas. Comes with mounting hardware and YOUR CHOICE of ONE antenna base, all of which bolt into the 3/4 inch hole: 3/8x24 stud, NMO and SO239. Also available at extra cost is an NMO radial base with four groundplane radials for 135-512 MHz. Your antenna simply screws onto any of our bases; your coax plugs into the bottom of the bases.  You can purchase additional bases at any time as all of them mount into the ¾ inch hole.

    • AMB-Bkt-1T  :  Heavy-duty (6x6 x 2.5" wide x 1/2 " thick) for medium/large HF antennas, with 3/4 inch hole (NO antenna base included; use the insulating washers and bolt that come with your antenna - we can also provide). Comes with mounting hardware. This was designed to fit the new Hi Q Antennas "ruggedized" and full size HF screwdriver antennas by High Sierra, Tarheel and others. This is also recommended for the Hi Q "4 & 5 series" antennas. All that is required are two insulating washers and the bolt for the base of the antenna (example shown in the second photo from the left). This mounting hardware comes with Hi Q antennas, and can be purchased for other antennas. This bracket can fit insulating washers up to 2.5 inches in diameter (and smaller ).

    • UHAM-200 : Universal-fit, adjustable, "two support points" mount for "any brand" of motorized/screwdriver HF antennas This is designed for antennas that need a second point of attachment while driving, such as the Hi Q "5 series" antennas and full-sized High Sierra and Tarheel antennas. This is STRONGER and has BETTER INSULATION than their mounts. Will fit essentially any antenna with a base diameter up to 2 inches (will NOT fit Hi Q’s "ruggedized" antennas).  Has a 3/4 inch diameter hole for mounting the antenna with your insulting washers and 3/8x24 bolt that comes with Hi Q antennas (available separately for other antennas, or you can "home brew" them).

   

    • AMB-Mast-D2.0 : Pair of stainless steel and cast aluminum V-clamps with hardware that bolt to VERTICALLY mounted CLAMPs (e.g. ladders), and will hold a light-weight antenna mast, pole or flag pole up to 2 inches in diameter (O.D.). This will fit some of the telescoping masts, and is great for small beam, dipole or inverted-vee wire antennas. Will also fit the BuddipoleTM mast (shown in the photo below), and their cool dipole antennas!.

 

  • 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).

    • 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. We also provide a custom designed and machined SO239 base for use with our UHAM200 mount.
