Hello Topbander,
My Shunt-Fed-Tower works well in a reasonable fashion
so far. (66 feet + 5el Tri-bander 3 feet above the top)
After adding a few buried radials as for CQ-WW-CW,
I encountered following strange situation.
(I don't think those radials caused this issue though..)
With using MFJ-259B,I can easily found 50 ohm(real part)
spot after changing Gamma-wire's position (distance
from the tower). Junction point of gamma wire is top of
the tower. Then,I changed the value of gamma capacitor.
Although I can reach zero-reactance spot as well,but found
one serious issue. What I experienced is the decrease of
the real part (not 50 ohm any more,but it moves down to
20ohm or 25ohm..etc.)
While I need more trial,I'm confused a little.
Does anyone encounter this kind of phenomenna?
