I'll be running the BC-375-E into my portable vertical as a pre-meet test. I get it to load into 50 ohm co-ax, but would a 4:1 transformer at the antenna be useful if I use co-ax? Maybe try it with 2 wires - one to the antenna, other to the radials (16)? 73 ES GUD DX DE Jim Falls K6FWT Eureka CA CN70ws
