Shortwave Coax Switch for Antennas
- Very simple schema that switches up to four antenna relays.
- Needs poer just for switching process, remains without during radio operation.
- Up to 1.5KW with GUNNER 18V bistabile 25A AC relay.
Example
The system contains of 4 PCBs:
-
The input switch box:
- 1x switch-matrix (ensures only one relay being active)
- 1x relais-with-led-indicator (keeps the state, has LED indicator)
-
The antenna switch box:
- 1x switch-matrix (ensures only one relay being active)
- 1x relais-with-led-indicator (keeps the state, LEDs optional)
