It is getting close *to winter times when decisions have to be made
for the seasonal antenna. My antenna is frequency independent with a
cavity / reflector and I have been feeding it via coax direct ie
unbalanced because of the constant impedance, therefore unbalanced to
balanced should not be a problem.
Anybody see an error in thinking here.
The antenna will be on a tower as the antenna picks up all
transmission modes so I need to get away from ground noise. I will be
adding an elevation changer if I have the time other wise it will be
parallel to ground or zero elevation.
Many thanks for your inputs

a dummy load up on the tower will work as well as one on the ground.


I was referring to the feed line. But since you brought up the antenna
I just noticed that it had only a portion of top band when resting on
the ground so I have to check it out on the tower before I move on.
Maybe just lifting it up a couple of feet will do the trick.
Eat your heart out dummy !


wow, only 2 posts till name calling started... must be a bad day for
art.
