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 interferrence on tv, computer, and home alarm.
Thanks for all the advice, really appreciate it.

Hi Bob,

Unfortunately you have proven that the BalUn was very effective in
doing what it is designed to do - prevent all the problems you have
now inherited from those who blamed your coax.

Mikes suggestion was the best - fix the antenna. The golden rule of
consulting is to give the customer advice they can perform. You are
limited to coax and they all had twin lead answers. Mike's suggestion
of making multiple dipoles AKA fan dipole is the simplest and quickest
(just make sure that you drop the ends away from each run by one to
two feet - the fan).

Actually the first to suggest the multiple-dipole approach was Steve KI5YG,
and that should indeed work extremely well, bearing in mind that the lowest
dipole should still maintain an angle from leg-to-leg of greater than 120
degrees, if possible. I use just one "fan" under the main resonant frequency
(around 60 meters), and it is also resonant at the tuned length of the
"fan", or second dipole as well. Using the tuner works very well up to the
required 15mhz range that my particular station requires. "Very well" to me
means that bareback testing is receivable from a station in Caracas,
Venezuela, which is over 2,000nm away.
