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.


You probably have a lot of feedline radiation.

Some suggestions:

Although I ordinarily don't care much for crossposting, you are going
to get so many different answers that your head will spin since you are
single posting your message to so many groups.

You should also take a look at some of these pages:

Your antenna is simply not the right length for the other bands. If you
even *can* tune with a coax setup, remember that you aren't changing the
impedence of the antenna, you are only providing a match between the
tuner and the radio. You will still have the coax/antenna mismatch to
deal with.
