You betcha, I have one and it is the best balanced tuner I have owned. If you are using balanced feed line you need a Palstar. ----- Original Message ----- From: "Larry DiGioia" <listacct@longwire.com>

With such a
variation in impedance at the transmitter end of the line there is no one balun transformer that will match it. Most of the time the impedance will be above
the 50 Ohms of your coax  so a high impedance balun would be desirable.
Unfortunately high imped&shy;ance baluns don't work well when not matched.

Here is what you really want:
