I have a couple yoyo dipoles, I've run them on vacations in the past and a
couple special event stations. The wire's a bit thin to leave up full time
which is why I didn't put it up here, but for what I have used them for, and
I even, that 2 months I lived with my in-laws ran one inside the house and I
can't complain about them, they're not bad. the hardest thing is finding
the tuning points and marking them, I marked them with electrical tape and
had a friend find them originally. They're not all that expensive, I forget
the price but I think I paid $30 for the one that goes from 2 meters to 40,
and I got another one setup to add wire to for 75 meters and they seem to
work well. I usually hung them with fishing line, I have one of those
antennas and a spool of fishing line in my go kit.
