I have a WS6BKW version of the G5RV hanging in a tall tree in an inverted V. I cannot tune 160m on it with an MFJ 941E external tuner. I have 50' of RG-8 running to it but the SWR is thru the roof on 160 (and 6 meters for that matter). This isn't my daily use antenna so I thought about modifying to determine if I can actually bring down the SWR on 160m. I have read that adding an ugly balun helps with SWR on these antennas. Also, turning the antenna into a doublet by eliminating the coax and running straight ladder line to the tuner may help but are either of these methods enough to lower the SWR on 90 something feet of wire? I have a small, city lot so I don't have many options to run long lengths of wire.
