Antenna for UHF VHF Links →
Array 2 yagi 5 elementi VHF
Le caratteristiche sono queste 5-Element 28-Ohm-Type Boom 2m, Gain 9dBd F/B > 20dB
Big wheel 432 Mhz
Simile ad un trifoglio, in parallelo nonche' in fase e posizionati a 120 gradi fra loro,coprendo cosi' una circonferenza virtuale
Built and tested his the antennas
These are mainly airs for UHF and SHF, for some in circular polarization satellite traffic requires
