Hi TT'ians I'm trying to built an 80/160 antenna with a Unidilla KW-80 trap. I can get the SWR on 80 OK, but my MFJ-259B doesn't like 160 so can't get a good reading there. How much wire do I need on the other end of the trap to get it to resonate in the 160 meter band?? Close would help as I can trim it as needed. Thanks and 73 Tom W7WHY
