VHF Ground Independent Antennas
VHF Ground Independent Antennas
The A – 212 is an extremely flexible, electrically designed ½ wave ground independent antenna utilizing a precipitation hardened 17.7PH tapered stainless steel whip. The whip is supplied with an impedance transformer that is air wound and encased in a fibreglass housing to ensure low loss.
The antenna has a mounting connector rather than a thread receptacle. This antenna mounts to a SO239 (CN-006) female connector, which fits a 5/8” diameter hole mirror or gutter bracket if required.
Tuning is by removing the set screw in the ferrule at the base of the antenna and cutting the whip to the required length with bolt cutters.

The A-212 is a ground-independent, half-wave VHF antenna with a precipitation-hardened tapered stainless-steel whip operating across the 148–175 MHz high band. Its air-wound impedance transformer sits inside a fibreglass housing, limiting signal loss. The antenna uses a mounting connector instead of a thread receptacle, and fits an SO239 female connector for mirror or gutter brackets if required.
- Ground-independent gain: 2.5 dB
- VSWR below 1.2:1
- 50-ohm impedance
- 4 ft (1,219 mm) whip length
- Tune by removing ferrule set screw; cut whip with bolt cutters
