The Comet GP15N is a high gain triple band base antenna made out of one section. For use on 50 / 144 / 430 MHz, wide band reception on 100 - 170 / 350 - 470 MHz.
The Comet triple band series were the first and are still one of the best in the market using Comet's SLC system. The SLC system is an advanced mechanism developed originally by Comet in order to greatly improve the gain on Dual and Triple band antennas. Through the implementation of the Air-Core Type Shaping Element Phase System and the Phosphor Bronze Element the loss during the existing Phase Shift Peak has been substantially reduced.
Completely factory tuned and no adjustment is necessary (50 MHz radial can be adjusted between 50 - 53 MHz). The fiberglass construction assures long durability and is fully water resistance.
