I had an 80M loop up for a while. Put a mast on each end of the house &
used some trees in the back yard. It was kind of a lop-sided pentagon
and up about 25' or so. I fed it 100W with ladder line & a Johnson
Matchbox. I was very happy with it. It was a bit of a cloud-warmer on 80
but did pretty well on the upper bands. I regularly used it on 20M for a
sked with a buddy in Indiana (from Arizona). A storm blew down a couple
of the trees or I'd probably still have it. I don't recall any RFI in my
house altho my neighbor had a problem with one of his el-cheapo phones.
If you have the supports, go for it...it's only a couple hundred feet of
wire and you might be surprised how well it works...
