Hey Bill,
Re: Your Tree Hung Loop

Interesting, that large of pipe for the radiator. You are helping paint
a more complete picture ... still some gaps.

Owing from Mike's post, this 3/4 in. CU pipe loop is 20 feet per side
on a square, and it's mounted in w/ a side parallel to the ground?

So that means there is a coupling inside the top section and a gap for
feed connection at the bottom. Is the top hung at the center and guys
from the top ends up to where the center guy attaches?

For the solder joints and weathering, what observations have you made,
including your other loops? I recall someone reported weakening after
what seemed like a short time out of doors.

-8db over the No. 12 model, nice.

One last thing, how are the feed ends finished for attachment: end caps
w/ bolt and lug attachment, or maybe soldered pigtail method?

Thanks, Peter
