Comet GP‑3N Dual‑Band 144/430 Base Antenna - Radioworld UK

Comet GP‑3N Dual‑Band 144/430 Base Antenna


The Comet GP-3N is a dual-band 2m/70cm base antenna built with a strong fibreglass radome for reliable outdoor use. It provides solid performance on 144 MHz and 430 MHz, making it ideal for amateur radio base station installations.

The mounting tube acts as a protective cover for the antenna cable, shielding it from the weather for long-term durability. A unique split-thread lock bolt secures the antenna to the mast—its compressed threads help prevent loosening over time. The antenna is designed to mount on mast pipes from 30 mm to 60 mm in diameter.
