Hi, all.
Can someone tell me what an acceptable SWR picture would be for a 102-foot
G5RV antenna?
I re-oriented my G5RV antenna today, by making the ladder-line run pretty
much vertically from the antenna feed-point at the top of my 35-foot tower,
to the coax that then goes into my shack from the base of the tower. I
checked the connections between the ladder-line and the coax feedline, and
they still seem to be good.
My SWR's are a bit better, and the auto-tuners on both my IC746 and Kenwood
TS480 now tune the antenna on 40 meters (which I couldn't say before), but
the SWR's still seem quite high to me.
On 40 meters, I get an SWR anywhere from about 5 to 1 down to about 4 to 1.
The antenna has its best SWR readings on 20 meters, which you'd expect, but
even here, I can't get the SWR to go much below about 1.8 to 1 in the center
of the band.
Again, at least now, the auto-tuners in both of my HF rigs will tune the
antenna, but I'm wondering whether it's even safe or wise to use the antenna
under these conditions.
