Topband: The band sans noise

[Bob K6UJ]

Hi Ken,

Be glad to.  It took me a while to get mine working, found some basic 
things I needed
to do and it now works very well.
First a question.  How far is your flag from the house and also
an antenna tower or other metal structures ?  I had to detune my tower 
it is only 40 feet away from
the Flag.  After this we can go over the construction of the Flag and 
its feed system issues like eliminating
common mode interference.  Maybe it would be best to discuss this 
directly rather than the reflector ?
I can be long winded.  hihi
