TG 4 High Gain VHF Antenna

The TG‑4 is a high‑performance VHF antenna engineered for reliable marine and base‑station communications. This mid-sized model provides increased gain for extended range and consistent signal clarity for voice and AIS applications.

The antenna features a two‑element design with a single phasing coil, delivering 4.5 dBd of gain. This configuration makes it a suitable antenna for larger vessels with moderate motion, fixed base stations, and HAM radio operators requiring reliable long-range communication.

The antenna is hand built and factory tuned to the selected operating frequency, chosen from the drop-down menu at checkout.

Its robust construction and performance make it well suited for demanding marine environments.
