In my opinion, the G5RV is a compromise antenna. Anytime you resotr to
matching stubs and shortened lengths, you are dealing with a compromised
antenna.
Having said that, there are plenty of people who get out decently on 80 or
75 meters using them. Key is installation and how you run the feedline
perpendicular to the antenna.
If you are confined to using a wire antenna, the best one you can do is a
decent length dipole i.e. 130 feet for 75 meters, fed with open-wire and a
tuner. You can work all bands with that. With the G5RV I used at our
FieldDay site a few years ago, I had good luck on 80, 40, 20, (10 meters
wasn't open); and it would not load on 15 Meters.

Hi Pat and all,
Since we're talking g5rvs, anybody using one on 80, who's getting out =
real good?
I'm just curious, because it would be nice to hear from someone on the =
list who has been very successful getting out on 80 with one! All the =
hams I've ever talked to have told me, that they're just average on 80, =
and some, nobody could hear.
So, if you're successful, let us know. It would be nice to hear of =
someone who gets out real well using one on 80.

Tom,
I have used G5RV antennaes for probably twenty years, installed high=20
and in the clear and low and not in the clear. I have never thought=20
they were any more likely to cause interference than any other=20
wires/beams that I have had in place. I am old school and still use=20
a low pass filter and perhaps that helps. I'll bet I still have one=20
lying around not doing anything if you need one.
Overall for a compromise antenna, I like the G5RV.
