G5RV at my home is that 2 of 15.5m length aluminum elements and 9.5m length(10cm width) balanced feeder and 1:9 balun. This G5RV has good SWR from 80m band to 10m band when this antenna has aditional 21m length coxial cable between end of feederto balun. I can operate 160m band when end of element connect to earth system.

	Balanced feeder of 10cm length width with plastic net. G5RV antenna is no relation with feeder's inpedance.
	This G5RV which is inverted V style antenna is good performance for JA's domestic communication.

1:9 balance-unbalance balun with 3 toroidal cores(left) AH2 antenna tuner (right) with common filter and 1: 9 balun

Result

This IV type G5RV antenna is good performance in domestic communication in Japa but not so nice for DX. So I changed my antenna from IV to V type G5RV for my DX on 80m band to 30m band now. So I changed my antenna from IV to V type G5RV for my DX on 80m band to 30m band now.
