Until recently, I had a) a 40m triangular loop in the back garden which I called a “micro-mega-loop” and b) a 60m loaded loop that allowed me to get on 80m. The two loops looked a bit horrendous not only because of the wire in the air, but because I used halyards to lift them in the air to the top of wooden stair rails. It was all very messy. They were also extremely close together along the back of the garden which meant some of my RF was absorbed by the other loop. See here: http://www.m0mcx.co.uk/sg-230-feeding-60m-skyloop-deltaloop/
I like loops for two reasons, a) for my small garden plot, I can achieve in half the size, what other do with a full size dipole and b) a resonant loop will also resonate on every harmonic, that means tuning a 40m loop at 7.1 Mhz means I also get 14.2, 12.3 and 28.4 Mhz.
