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)
