Have seen a simple solution but not tried it. Try a few 5W carbon or thin film resistors in the linear, going from the ground near the input to the input pin that the relay switches the center pin of the coax to while in operation. Perhaps a few 100 ohm in parallel. I think this will help soak up and balance the reflected seen by the radio when in operation. Perhaps you can experiment with the value. Tuning via capacitor is also possible as mentioned. Try to find schematics of other amplifier designs that use such input tuning and copy where they placed it with perhaps some auxiliary components working along side it. I need to brush up on my amp building skills.
As seen in a youtube video. lol
