For a list of which bases fit our various mounts, refer to our mount web pages or the "Antenna Base Options" column in our PRODUCT GUIDE , which can be viewed and download in PDF format. We have grouped various types of antenna bases according to which mounts they fit, as shown on the product guide ("Groups 1-7"). You may find our PRICE LIST  is handy, which lists our products, options and parts.

==> We offer a discount on shipping if these bases are ordered with one of our compatible mounts - order the bases on the MOUNT PAGE for the automatic discount - or CONTACT US for a quote. 

==> If you only want to order one or more antenna bases, without a mount, please order them below on this page.




Our "Standard" Antenna Bases: 3/8x24 Stud, 3/8x24 Antenna Mounting Kits, NMO & SO239

These bases fit most of the HF/V/UHF mobile antennas and many of the HF screwdriver and motorized antennas. For a list of the mounts they fit, see our  PRODUCT GUIDE . 

We add extra stainless steel hardware, if required, so these bases will mount into a 3/4" diameter hole and are therefore INTERCHANGEABLE on our mounts. Also, if you buy one type of base you can always buy another later if you get another antenna - they will fit! Some of them will also fit a smaller hole without the included custom hardware.

3/8x24 stud base: heavy duty 3/8x24 stud antenna base with SO239 on bottom - fits  3/4" hole, panel up to 1/4" thick. Chrome plated and stainless steel. This will also fit BuddistickTM vertical antennas.

3/8x24 "Antenna Mounting Kits": pair of insulating wafers, 2 inches in diameter, with your choice of three lenghts of 18-8 stainless steel antenna base mounting bolts - everything shown in the photos below. Also includes a large diameter flat washer, standard size flat washer and lock washer. For these bases, you fasten your coax center conductor using a 3/8 inch solder lug (not included) and the coax shield to the 1/4 inch bolts on our mounts. If you don't have the solder lugs, you can order them on our PARTS page. These are all compatible with our "SHD-SO239-LA2.0" adapters that allow you to plug in your coax plug on antennas that are mounted with a bottom bolt - see the "LA2.0" information below - you do NOT need the "LA" for these kits. We currently provide the following bolt kits and can provide additional ones if there is interest (contact us):

  • AntMtgKit_1-3/4:   1-3/4 inch long, 3/8x24 bolt with the hardware and insulators mentioned above and shown in the photo below. Typically fits our mounts that have a panel thickness of 1/4 inch.
  • AntMtgKit_2:   2 inch long, 3/8x24 bolt with the hardware and insulators mentioned above and shown in the photo below. Typically fits our mounts that have a panel thickness of 1/2 inch.
  • AntMtgKit_2-1/22-1/4 inch long, 3/8x24 bolt with the hardware and insulators mentioned above and shown in the photo below. Typically fits our mounts that have a panel thickness of 3/4 inch

NMO base: high quality NMO base with SO239 on bottom - fits 5/8-3/4" diamter hole, panel up to 7/8" thick, includes custom HD stainless steel (SS) hardware for 3/4" holes. Notice the special nicely machined, rust proof, HD nuts we use (Ni plated brass) - you won't find these on most antenna bases!

SO239 base ("PL259"): high quality SO239 base (2" barrel) - fits 5/8-3/4" hole, panel up to 3/4" thick, includes HD SS hardware for 3/4" holes. Notice the special nicely machined, rust proof, HD nuts we use (Ni plated brass) - you won't find these on most antenna bases! We offer the same SO239 with the same nuts (without the two large washers) on our 2 inch long SO239 barrel connector that we now sell.

NMO Base With Removable Groundplane Radials (135-512 MHz)

NMO base with radials:  high quality NMO base with 4  removable, 18 inch long, stainless steel groundplane radials (135-512 MHz)  & SO239 on bottom - fits; 5/8-3/4" hole, panel up to 5/8" thick.

This special NMO base allows you to use your 135-512 MHz mobile antenna with an NMO base on a non-metallic surface since it comes with groundplane radials, with your own bracket, the CLAMP150 , or our "L" mounts. This is the same base that comes with our AMB-Arm2 second antenna bracket - minus the 13 inch second antenna bracket. This NMO radial base mounts into the 3/4 inch hole with provided mounting hardware that includes the large stainless steel flat washer and nicely machined heavy-duty nuts (not the thin nuts or poorly machined HD ones that come with most SO239 connectors).

For a list of the mounts that this base fits, see our  PRODUCT GUIDE .

The top photo shows what you get - including the Allen wrench for quickly removing the groundplane radials. The second photo shows the same base with radials installed on our AMB-Arm2 second antenna bracket arm.

Please note that due to the length (18 inches) of the four radials, this item has to be shipped in a larger box (reflected in shipping price).

"VersaBase" for BuddipoleTM dipole antennas

VersaBase: for BuddipoleTM dipole antennas, made of heavy-duty aluminum and stainless steel components and will support even the longer radials, without a mast or guy wires.

The bottom bolt that fastens the VersaBase to our mounts is 3/8x16, 18-8 stainless steel, with a wing nut for quick installation and for loosening to rotate your dipole antenna. Fits your bracket or our mounts with panel thickness up to 1/2 inch, and thicker with a longer bolt that is easy to obtain and install. A standard Buddipole Versatee (not included) quickly screws onto the top of the VersaBase. Works with horizontal, sloped and L dipole configurations. Very quick, heavy duty and simple!

You may be interested to note that we have two antenna bases that fit the various types of BuddioleTM antennas - see the photo below:

  • Our "VersaBase" - for BuddipoleTM dipole antennas that use the innovative Buddipole Versatee dipole antenna adapter. Please read below about this base.
  • Our "3/8x24 stud base" - for BuddistickTM vertical antennas, which are one half of their dipole systems. This base is describe at the top of this page.

Either of these bases fit our CLAMP-150 and some of our AMB "L" bracket mounts - for a list of our compatible mounts see the "Antenna Base Options" column in our PRODUCT GUIDE.  For information on Buddipole antennas visit http://www.buddipole.com/ . 

Below you find information on the new VersaBase. You may want to check out the INSTALLATION MANUAL for our VersaTee base.

The photos below show what you get with the VersaBase (Versatee not included, is provided by Buddipole) and one example installation of a BuddipoleTM dipole on our CLAMP-150 clamp to anything antenna mount.

SHD_SO239_LA Series: SO239 Adapters for Bolt Mounted HF Screwdriver and Motorized Antennas

 SHD-SO239-LA: compact "L" bracket with heavy-duty good quality Ni plated brass SO239 connector for plugging in coax to antennas mounted with a base bolt. Comes in hand buffed aluminum or five powder coated finishes. We have two models that only differ in width and size of solder lug:

  • SHD_SO239-LA-2.0: for antennas with base diameters up to 2 inches. Includes a very short jumper cable with 3/8 inch heavy duty solder lug. Compatible with our AntMtgKits described above. Compatible antennas include:
      • Hi Q Antennas "standard" motorized HF antennas with 3/8x24 base bolt 
      • High Sierra "Sidekick", HS1800 and others.
      • Tarheel small and full sized models up to 2 inches in diameter at the base.
      • other brands with base diameter up to 2 inches and 3/8 mounting bolt.
  • SHD_SO239-LA-2.5: for antennas with base diameters up to 2.5 inches. Includes a very short jumper cable with 1/2 inch heavy duty solder lug. NOT compatible with our AntMtgKits. Compatible antennas include:
      • Hi Q Antennas "ruggedized" motorized HF antennas that require a 1/2x20 base bolt. 
      • other brands with base diameter up to 2.5 inches and 1/2 inch mounting bolt.

    Both models are the same, except for the width and size of the solder lug. The jumper cable is 12 gauge stranded copper wire. The white tube is a short insulating part to help align the "LA" to the 3/4 inch diameter hole in the mount and to help prevent the antenna bolt from shorting against the inside of the hole. If ordered with a powder coated finish, they come with a special custom made aluminum grounding washer (shown in 3rd photo below) for grounding the "LA" to the mount, past the insulating powder coat finish - we pay attention to detail!

    For a list of the compatible mounts, see the "Antenna Base Options" column on our PRODUCT GUIDE .

    You may want to check out the INSTALLATION MANUAL for our SHD-SO239-LA series antenna bases.

    PHOTO BELOW: The two models, shown in buffed aluminum. Also available in five powder coat finishes.
