WebA typical ground station includes a 2-meter FM transceiver and 25-100 watts of output power. A circularly polarized crossed-Yagi antenna capable of being pointed in both azimuth (N-S-E-W) and elevation (degrees above the horizon) is desirable. But successful contacts have even been made with verticals and ground plane antennas. WebFor two purposes a Cross-Yagi can be useful: Satellite work or if you need both vertical and horizontal polarization for terrestrial contacts. You can use two different feeding methods: Always cross polarization or switchable …
