Hi, Thank you for your response. I do not have ladder line and only have the
coax basically. Is it acceptable for good results to simply use the coax and
then split it out to each direction of the copper wire? And not use the 1:1
balun? I was hoping to simply get the dipole in the air and leave it and
simply tune it at the transmitter to acceptable SWR and go from there. Now I
only get good SWR on the 80meters because of the length it is cut at. I was
hoping also to use the dipole with the tuner on 10, 15, 20 and 40. Is this
possible? The tuner is good and I know I will lose the power to the tuner
but would still get to use the other bands when needed.
Any more advice is greatly appreciated.
thanks
Bob

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. 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.

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

Is the fact that the dipole is still too low and close to the guy wires

(
but not touching) our problem?


Bob, the antenna as you describe it is pretty much *for* 80 meters. If
you want to tune the thing on multiple bands, and I'm assuming that you
want it for the Ham frequencies, you will want to replace the coax and
balun with ladder line, and use a tuner to match the impedence with your
radio.
