Description
The SDA All Relay is the all inclusive relay board for the SDA 100 and OptimizIR controller. This relay board features the 3 relays needed to operate the DB style antennas and includes the amplifier lock-out relay. The lock-out relay connects via PTT cable to RF power source and prevents the amplifier from transmitting while the SteppIR antenna is being tuned. Helps prevent potential mismatch issues that could damage the antenna.
