For lightning protection I use Polyphaser Devices on all Coax entering the house including lines from Beverage antennas. You also have another situation to think about. That is killing the front end of your receiver with your own transmit signal. Unless in your W8JI setup is also included some fast relays to disconnect and ground the RCV only input during transmit cycle. If you need one take a look at the KD9SV Products for Front End savers several also incorporate Preamps and switching for various Rcv antennas. Within the front end saver device is also arrangement whereby if the Relay that removes and grounds the RCV antenna doesn't work for some reason it won't allow you to key your Amplifier.
