Sirio GP3E | 135-175 MHz Mono Band Base Antenna

The 'Sirio GP3E' is a omidirectional low gain, mono band base station antenna. Suitable for land and marine service.

It works on the frequency range of 135-175 MHz by using the tuning diagram enclosed. The matching coil is DC feeded for a perfect protection from the static discharges. GP 3-E is made of non-corrosive aluminium and assembled on a very strong base of die-cast metal to get the maximun robustness and the best performance. Tuning is easy by following the attached directions.
