Shaun,
For materials needed vs. radio theory, you just can't beat a G5RV antenna.
IMHO I've used mine with my K1, K2 and several home brew projs and it works
great time and again. Yes, you want to get the center up there a ways. Say
around 35-40 feet, but the payoff was good for me. There are a number of
sites out there that have good versions of a very old, classic antenna.
Very few parts (all of which can be made with junk around the house. Very
little investment for a sound payoff.

Subject: [Elecraft] dipole antenna efficiency
Hi all,
if I were to make a dipole, would coiling it round a piece of plastic
piping decrease the efficiency of the thing? I intend on making one for
40 meters, one for 80 meters, and one for 10 meters. I've worked out
that1 meter of piping will suffice for each leg of each antenna.
thanks in advance.
