RHA68 Suunta-antenni 66-78 MHz 3-elementtinen 7 dBi 50 Ohm UHF-naaras (SD-68 68-78)
Sirio
Sirio SD 68 is a high-quality directional dipole antenna designed for the 68–78 MHz VHF Low Band. It is an excellent choice for RHA68 village radio systems, public-safety communications, industrial sites and other fixed VHF Low Band installations that require reliable performance and reduced interference.
The directional design concentrates the signal in the desired direction, improving connection quality and reducing interference. The Gamma Match feed provides good matching across the operating range without separate tuning. The antenna can be installed for vertical or horizontal polarisation, and its durable aluminium construction and weather-resistant materials ensure a long service life even in demanding outdoor conditions. All metal parts are DC-grounded to help protect the system against static electricity.
