I put up a 73' dipole antenna between two trees and hooked it up this week. The antenna is above the house and about 20' away. I let the ladder line droop until it was even with the eaves, then ran it along the eave to the balun. From there, I ran the heavy 400 coax down to a surge arrestor attached to a copper grounding bar, then another coax back up to a pass-through in my second floor window, then another length of coax to the Icom IC-7300. This was the wiring plan suggested by someone at Ham Radio Outlet to address my grounding concerns operating from a second floor. It will probably come as no surprise that the SWR is pegged and the built-in tuner in the 7300 just beeps once and gives up. I tried running the coax from the balun directly to the radio, but the results are the same. I don't know if I'm misinterpreting the radio's SWR meter or if I really have a problem here. Don't want to burn out the transmitter. Desperate for help. Anyone want to tackle this?
