Hi!
Anyone had any experience with a G5RV which is NOT symetrical relative
to ground?
Mine is on a sloping section and varies from 3.2 metres AGL at the
western end to 7.5 metres at the Eastern. Although I get a reasonable
match with a single coil Z match tuner I have reason to believe that
there is quite a large electrical imbalance in the system, notably in
the poor rejection of local noise signals.
I came across a Z match circuit on optushome.com.au by VK3YSF which has
a 25 pF variable capacitor from one side of the open wire feeder to
ground. However the article gives no further information about this
component except to call it a "Balance" capacitor.
Has anyone else come across this problem? If so was it a question of
"cut and try" or is there a proper technical approach one can use?
Hoping for some "feedback".
