Correction to my last post. Operating from memory (when it's bad) is not good. The antenna is connected to the RF unit. a reed relay is switched on in rx to route it to the RX front end. When in TX mode the RF from the LPF unit is routed thru D44 and directly to the antenna. The reed relay opens up to protect the Rx front end. There is only 1 diode but 2 chokes to provide a ground path for it.
