Force 12 shortwave beams

F12 Logo

Force-12 (USA)manufactures multiband beams and also verticals.
Force-12 beams don't use traps but consist of several monoband yagis on one boom. Due to the patended "open sleeve" feeding system usually only one feed line is required. No traps means no practical power limit: unless otherwise noted the beams have a max. power rating of 5kW SSB.
All antennas come pre-assembled, the element supports are already attached to the boom. Each tube set for each element is bundled and marked. The elements are riveted for extremely solid and long time endurance. The boom mounts come in two parts and are very easy to assemble, so you don't need a third hand to mount the antenna.
Each antenna is assembled at the factory and disassembled again for shipment. Due to the small shipping size and low weight, Force-12 antennas are often used at major DX-peditions. Force-12 does manufacture more than 100 models, we show the most often used ones.

C-Serie

Info freight charges


Multiband yagis for 10 - 20 or 10 - 40 meter bands. The antennas are designed for the traditional bands, but also have a little gain on WRC bands (tuner required). Withstands max. 128 km/h wind speed, models for higher windloads are available on request.

C-4SS 7 element, 6 band beam

The C-4SS is similiar to a C-3SS plus an additional 40m element with linear loading. So this antenna is a very compact multiband beam für 6 bands (10-40m, expect 30m). For thechnical data please see the table below.

C-4S x-Element 5-Band Beam

C-4S

The C-4S is a C-3 with a 40m dipole added. This 40m dipole is shortened by "linear loading" and has a length of only 9m. This antenna requires two feedlines.
