Palstar AT2KD Manual Antenna Tuner ...: For Sale: Palstar AT2KD. You know what these are … simply one of the best manual tuners on the market. Current price is about $800.

Includes wall wart, extra power cable, original manual. Price: $500 FedExed to your door. Cashier’s check or P.O. Money Order … no way to deal with electronic payments.

Johnson Viking Matchbox For Sale: Johnson Viking Matchbox For Sale:
-
The old timers know what a Johnson
Matchbox is. It is a very rugged
antenna tuner, built like a tank.
Basically, it will match most anything
you connect to it. It is ideal for
balanced lines.
-
This one is better than most, in that
it has the SWR meter built in to it.
It even includes a sensor, so that the
SWR bridge works. Most have lost the
sensor!
-
This one is designed to handle 275 watts
of AM.
-
This one works just as it should.
Cosmetically, considering its age, it
is in extremely good condition.
-
This one even has the manual with it for
$220, plus shipping from Florida.
-
Thanks. 73,

Palstar AT1KP Tuner- Price Lowered: $245 shipped. This is an older 1.2KW differential tuner. The "cheapo" plastic coupler on the inductor knob shaft has been replaced with a commercial grade metal & ceramic one. The light is burned out but will throw in a couple if you want to replace it. Good shape- never ran over 800 w thru it. Works great; just replaced with an auto-tuner so I no longer need it.
Sold "as -is" and shipped to lower 48 states only. Zelle, PPal, cash or Money orders ok. Pick up for $220. Questions?
