Anyone suffer from poor tune on 20m when the Midi loop gets wet? When I build this one I noticed that the Gamma match tubing had a badly seated cap, when I removed it to inspect a few drops of water came out of the tube. Am going to take the loop down today and inspect this again as its been quite wet recently but am interested to know if this is a known issue. This is a used loop and as far as I know it was stored indoors prior to my assembly and when I did the build, the loop was only outdoors for about 2 days before it went on the mast. Was rather surprised to see the water and trying to tun last night when raining, 20m was nothing below 2.1, today now its dry kinda back to normal at 1.6 ish. Real concerned that water is getting into the co-ax section and thats bound to be bad news.

Mmm, I'd be thinking that low rail would detune the loop quite well when wet. The tow small bushes at each end would drive it mad too. I reckon if you give the loop clear space it would tune much better in the wet.
