Sorry for the delayed response. Yes we get our share of lightning. Highest point on the loop is about 70 feet. The antenna, when connected, has no part of it grounded. When dis-connected, both ends of the loop are totally clear of the feed-line, and are connected only to an 8’ ground rod. It’s a little hassle to go outside and hook up to operate and unhook when done. Ungrounded loops with twin lead all the way into the shack are inherently susceptible to lightning strikes. Stuff you likely already know. It’s always fun but never as impressive as CW QRP work.
It’s balanced feed-line. I guess people call it window line because it goes through windows easy? Feed-line like this has a radiation risk if not done correctly, the key is to insure it remains balanced all the way to a balanced antenna. It has advantages as it is very low loss compared to coax and is compatible with a balanced feed (Palstar BT 1500A) from the shack. Using it requires more care than running coax, and most HF equipment is designed for an unbalanced 50 ohm coax connection (safer and easier). Thanks for watching.
I have no idea what any of that does... but I like the exposed tech look. Modern artist call it steampunk I think
Do you get a lot lightning strikes around/near your QTH Trent? You have a nice looking station. Terry KB8AMZ.

What kind of loop are you running? A 80 meter delta?
160
Isn't that really window line ?
