Comet GP-1N – 1.25M Dual Band Antenna


Comet GP-1N high gain dual-band antenna for 144 MHz and 430 MHz.


Comet offers a 2 m and 70 cm band station antenna comparable to the Diamond X-30N. The workmanship is high quality, a subsequent tuning (SWR) is not necessary. The Comet GP1N is also suitable for mast mounting.

A very compact base antenna using Comet’s SLC-system, (super linear converter) for a low loss, high efficiency antenna. Wide band coverage means no tuning is necessary in both bands, and high-quality fibreglass ensures waterproofing and a longer working life. Additional use of a comet duplexer would also allow full duplex operation.
