There are two antenna systems in use. A three antenna stack of M2 20M5HD rotatable beams at 159/106/53' using a Comtek SYS-3 Stack Yagi System and a two antenna stack of Hygain 204BAS rotatable beams at 33/53' with hard phasing. Both are selectable and can be alternated for TX and RX (listen on one, transmit on the other). A remote TH7 antenna can be used for receive.
20M High Stack
The 20M5's are M2 20M5HD antennas with the heavy duty booms. Each beam is mounted on a two motor TIC ring using GHE controls. All controls and switching are performed with microHam Stack Max switches. Any combination of the antennas can be selected.
