[ICOM] Receive antenna input?

Ok so I do need protection if I decide to go into this output.

 I may end up using an antenna switch to go between the rx loop and my transmit "T" vertical as I am sure the e and h fields are
probably pretty strong anywhere I could place the rx loop.

The loop itself may not even make it through the xmit cycle. I am not on a very big piece of land out here so the rx loop will
definitely be in the near field to the xmit antenna.

  73 fer nw,
