Howdy,
I'm no antenna expert, nor do I claim to know a whole lot about the
ins, outs, or other technical data about the G5RV. I speak only from
EXPERIENCE.

>there is a necessity of a 32ft tower, isn't it?
I have my G5RV strung between two trees diagonally across my entire
property. It gently slopes from the spruce at about 25 feet to a tree of
unknown ancestry at about 10 feet. It rests on the roof on the way at
about 15 feet.
>1) Will the G5RV cover 40/80 meters with a reasonable performane?
What's "reasonable"? I've worked 80 a bit and I know it has reached
about 1000 miles away with only 100 watts.
>Does it require a standard Antenna Tuner?
From my understanding, yes. I use the automatic antenna tuner that
goes with my Yaesu FT-757.

Don't know if my antenna is SUPPOSED to be 5 meters above the roof.
Mine isn't. Sometimes it gets hung up on a metal vent, which I know is a
"no no".
>3) Does it work in an inverted V configuration?
I've heard that it does, but not well. The recommended angle is at
least 90 deg.

Don't know. I got mine from Antennas West. It is also fairly easy to
build yourself. I would have built one myself but was chicken at the
time. I've gone on to build a dipole and vertical out of junque from
around the house.
Hope this helps. As I said, I'm no expert, but I do know that my
antenna works for my extremely modest purposes. I use it for all bands
now, but would like to get my tower up with beam for 10, 15, and 20.
