"AMB-Bkt-1" Standard "L" bracket for most HF/V/UHF mobile antennas, with choice of antenna base (OPTION 2): $45.00 USD
AMB-Bkt-1: Our standard "L" bracket for mounting most HF/V/UHF antennas. Comes with YOUR CHOICE of 3/8x24 stud, NMO or SO239 base. You can also order all three if you'd like, as they are interchangeable.
All bases come with heavy-duty hardware that will fit into the 3/4 inch hole in the "L" bracket, including large nickel plated nuts - not the flimsey nuts that come with most SO239 connectors. The 3/8x24 stud base is the heaviest duty one we could find - the manufacturer rates it for well over 2,000 watts! The bases are interchangeable and can quickly be removed and another type installed, if you have different antennas or buy a new antenna "with another base".
The bracket is 1/4 inch thick, 2 inches wide and 4 inches "deep" on both sides. Included are two sets of 3/8x16 stainless steel mounting bolts with the hardware shown in the photo. You also get a 1/4x20 bolt with wing nut and heavy duty solder lug for 16-12 gauge wire, to use as a ground point or to mount our "AMB-Arm2" second antenna extension arm. With the Arm2, you can mount an HF antenna (or V/UHF antenna) and then install a second V/UHF antenna. The Arm2 is described and can be ordered below.
Be sure to select the type of base you want. If you want to order additional bases, click > PARTS & ACCESSORIES .
** United States Customers: Shipping $9.00; $4.50 for each ADDITIONAL UNIT

"AMB-Bkt-1-T" Thick "L" bracket for Hi Q and other antennas (NO BASE) (OPTION 3): $25.00 USD
AMB-Bkt-1T: Our thick "L" bracket for mounting larger HF motorized / screwdriver antennas that utilize thicker (e.g. 1/4 inch) insulating washers and that mount with a 3/8x24 bolt into the anteann - such as what Hi Q Antennas provides with their motorized HF antennas. It does NOT COME WITH A BASE, although our NMO and SO239 antenna bases will fit into the 3/4 inch hole (our 3/8x24 stud base WILL NOT FIT, due to the thickness). The bases can be ordered separately by clicking > PARTS & ACCESSORIES.
This was originally made for the Hi Q Antennas antenna mounting kit that includes 1/4 inch thick insulating washers. The bracket is 1/2 inch thick, comes with stainless steel mounting bolts and has a 3/4 inch hole for the special Hi Q Antennas mounting hardware that comes with their antennas. It can be used for other applications as well, where you want a thicker bracket for large antennas. Please note that the photo below shows a 1/4 inch "L" bracket - but similar in other dimensions to the 1/2 inch THICK AMB-Bkt-1-T.
The bracket includes two sets of 3/8x16 bolts and hardware, and the 1/4x20 bolt, wing nut and heavy-duty solder lug - same as the AMB-Bkt-1. You can also mount our AMB-Arm2 (described below) to this thick bracket. You get the hardware shown in the photo below.

The photo below shows one example, with Hi Q washers and antenna installation kit, for our CLAMP-200 antenna base.

AMB-Bkt-2: Our standard DUAL "L" bracket for mounting most HF/V/UHF antennas. The double L brackets allow you to swivel your antenna, and can be mounted to a vertical surface such as the top of a railing, pickup bed wall, and many other surfaces. It comes with YOUR CHOICE of 3/8x24 stud, NMO or SO239 base. You can also order all three if you'd like, as they are interchangeable.
We also offer a SPECIAL NMO base with four stainless steel radials, for 135-512 mHz (2m-70cm & GMRS band). For information on this, click > PARTS & ACCESSORIES .
All bases come with heavy-duty hardware that will fit into the 3/4 inch hole in the top "L" bracket, including large nickel plated nuts - not the flimsey nuts that come with most SO239 connectors.

The bases are interchangeable and can quickly be removed and another type installed, if you have different antennas or buy a new antenna "with another base".
Both brackets are 1/4 inch thick, 2 inches wide and 4 inches "deep" on both sides. Included are two sets of 3/8x16 stainless steel mounting bolts with the hardware shown in the photo.
