I doubt the TV antenna is affecting the dipole. You may have broken the
dipole or feed line when you put up the TV antenna.

Also check to see that you did not put the TV feedline too close to the
dipole feedline. It should be atleast a foot or more from it..

Hi
Thanks for all the info and advice and ideas.

I have the 102 foot dipole up there now, my problem is I just put a TV
antenna HD (two 8 bay bow tie Channelmaster) antennas right above the
dipole's center point (about 1 meter away) and now I am having difficulty
tuning that dipole for anyband. In fact if I try too long the old 1970
transceiver shuts off automatically and scares me that I may have some of
that blue smoke you talked about. So I wanted to get something above it,
omni that would work as well as the dipole did work. Something simple, and
easy becuase nothing up there on the top now.

I think as you folks mentioned the omni fed with coax at short lengths
will be difficult unless it is long enough and with gnd planes, but first
wind storm will bring it down.

I will focus back onto the dipole. Do you think it is too close to the new
TV antennas? Would that cause the innability to tune it where I was able
to before through the manual tuner?

What would be a suitable distance from the center point of that dipole to
be away from anything that would cause such innability to tune. Right now
I am thinking one of the legs of the dipole are fractured and that is the
problem. I don't have a way to test each leg of the dipole, it is about 50
feet of ladder line and then each leg but how do you test from the shack
if there is a fracture without the fancy scopes that you guys have? Other
than bringing each leg down and using ohm meter from one end to the other.

Any comments about having those channel master HD antennas too close to
the center feed point of a dipole? And the havok it can do to an old
transceiver and tuner?

Thanks
