Joshua,
You are already planning to hang the G5RV so can you put up a 20-foot
pole at the far end? That provides lots of bands and cost little
extra. The 2m/70cm vertical sounds fine.
You could load the tower as a vertical with a tuner. One way is to
run a vertical wire up to the tower top from the tuner and tie the
wire to the tower top with a short side arm so the wire is parralel
and offset to the side of the tower 6-12 inches. This forms a folded
monopole which you ought to be able to load on several bands. Sink a
ground rod at base of tower and see how that works. Not as efficient
as having radials but sounds like you are renting and have limitations.
I have a 3-element triband trap yagi and I run it on 18m by use of a
tuner fairly well. It does not work as well on 24m, though I have
made some contacts.

------------------
Ok, I know that this is a topic much like the Ford vs. Chevy debates or the
Android vs. Apple debates, but I do have a few questions...
I am going to be acquiring a 56 foot Rohn BX tower. I already have a G5RV
that I am planning on putting up (still not sure where I'm going to attach
the other end of it to, One end will go on the tower.) I'm going to put up
a 2m/440 vertical at some point up near the top of the tower. I keep
throwing around an HF vertical or a beam. The verticals seem to cover more
bands, but the beams are directional. (Would also need a rotor,..
Can a multi band yagi be tuned to a different band, or will it only work on
the bands that it's designed for?
I'm thinking long term and I'll probably be adding a K3/100 with a KPA500
to the mix in the next year or so... Trying to figure out what will give
me the best bang for my buck, so to speak.
