I have an Indoor 2 x 8 Antenna Genius. It has worked just fine for a long time. Recently in the VHF contest I experienced a high SWR event that at first I thought was the SWR meter failing (it didn't); then I thought the AMP had fried itself (it didn't). As I test the radio barefoot with new coax into the AG I note that ports 1 and 2 show high SWR (DB36 and KT34XA) and port 8 (Dummy Load) shows perfect SWR. Does it make sense that I could take out a port I was using and the one adjacent to it with 1000W of FT8 on 50MHz? And if so, how does one go about verifying and fixing it?
Thanks in advance!
