Hi all

I have it back up without the balun, and still have to use the coax for now.
I am able to tune it now on all bands but I am sure there is a lot of power
loss from the tuner. I grounded out all devices in the shack but still
receiving a lot of RF interference on tv, computer, and home alarm.
Thanks for all the advice, really appreciate it.

Hi
We have put together a dipole, each leg is 66 feet. We put a 1:1 balun
and
it is running about 60 feet of 50 ohm coax. Presently it is about half
way
up the tower it is intended for so we could check the SWR before getting
it
up to the highest point. Presently each leg has some lags and dips, no
major
bends but it is just hanging there, over some bushes and the entire
thing is
over top of the house, and not touching anything but is very close to
some
steel guy wires (uninsulated).
Now we can only tune this down to a useable SWR on the 80m band.

That is normal, without the tuner...
On all
other bands we cannot tune it down to a safe operating range. We are
using a
good antenna tuner but cannot get anything useable except for 80m. Here
we
are able to tune the SWR right down.

Thats not totally normal, but could be a tuner deficiency...

Questions???
Would we be better without that balun?

No, it's 1:1.

Is the fact that the dipole is still too low and close to the guy wires
(
but not touching) our problem?

That can mess things up, for sure.

Any suggestions please??

#1, feeding an all band dipole with coax is a mistake. Your feed
losses will be very high on most all other bands, except 80. If you
want to use it for all bands with a tuner, you would be better off
feeding it with ladder line, or twin lead. MK
