RHA68 base-station antenna 66-78 MHz 2.15 dBi 50 Ω UHF-female
Sirio
Sirio GP 66-78 LB-U is a high-quality omnidirectional 1/4-wave ground-plane base station antenna designed for the 66–78 MHz VHF Low Band. It is an excellent choice for RHA68 village radio systems, local communications, public-safety networks and other VHF Low Band applications that require reliable 360° coverage.
Thanks to its broadband design, the antenna requires no separate tuning across the 66–78 MHz operating range. The DC-grounded feed helps protect radio equipment from static electricity, while its weather-resistant aluminium construction ensures a long service life even in demanding outdoor installations. The omnidirectional radiation pattern makes it an excellent choice for base stations that need to serve users in every direction.
