Vertical Polarization 2m 8Element FM Wideband Antenna 2m8WBRV
FM simplex or repeater rear mount vertical polarization 2m 8Element FM Wideband Antenna 2m8WBRV could be put on any mast or balcony to get the farthest repeaters or FM simplex friends. 3m boom and 8 elements will give you the maximum gain for the rear mount antenna.
2m 8element FM wideband antenna 2m8WBRV vertical polarization
Vertical polarization 2m 8Element FM wideband antenna 2m8WBRV could be produced in two versions:

Antennas-Amplifiers Product Benefits. A Major advance in Amateur Radio antenna design.
- F/B and G/T superiority.
All antennas have been calculated using state-of-the-art full 3D Electromagnetic Simulation Software including the influence of the boom, bracket, baluns, and connectors. The performance of antennas designed using these techniques is exceptional, far better than antennas designed using “wire” programs.
Comparison of EM simulation software
- No tuning antennas
Before dispatch, we assemble each antenna and test antenna characteristics. That means you may expect excellent electrical and mechanical attributes including low SWR across the designed range immediately after assembling.
No need to tune the dipole, or any other element to get perfect SWR on the intended frequency range. Everything is pre-tuned.
- Easy to set up
Everything is labeled, just put number to number. The antenna can be assembled with hand tools in a couple of minutes.
Everything is included in the antenna box: Antenna, balun with connector, and bracket. Yours is to assemble and have fun!
The old name of the antenna was PA144-8-3RBGV
