Hi Bob,
Good luck on your project.?
The relays must be sequenced so that the output relay is connected to the antenna before the amp input relay closes.? Likewise, the input relay must open before the output relay is removed from the antenna.? This assures that the amp is always connected to the antenna when there is possible RF at the input of the amp.
