I have two fairly unusual Swan items available.

The Swan MMBX Antenna "Match box" and the 14-C DC power supply are For 
Sale.

.

Swan MMBX Antenna Matchbox

This unit is designed to go between the base of an HF mobile antenna 
and your rig.  It is designed to transform the 50 ohm impedance your 
rig would like to see to the impedance that is at the base of your 
mobile antenna, which is usually lower.

It is in a fairly heavy duty metal box about 3 x 3 x 4 inches in size. 
  There is a 7 position switch that lets you switch to the position 
you need to match the impedance of the antenna.

Specs say it will work from 2 to 30 MHz with up to 500 watts power.

This one works as it should, and looks extremely nice -- close to new.

I only found two that had been sold -- one for $34 (a parts unit) and 
one for $40.  Buy this one for $35.

Swan 14 C DC Power Supply

This is a DC power supply intended to be used off of 12 V DC, and 
power some (Most??) of the Swan rigs.  It has a 15 pin Jones socket on 
it.  I have been told it plugs into the back of some Swan rigs.

I applied 13 V DC and watched the ammeter, and it shows no shorts. 
Beyond that, I have no way to test it, but think it likely works OK.

Buy it for $50.

.

I also have many other accessories available such as many
different types of microphones, HTs, VHF and UHF rigs, HF
and VHF/UHF antennas, connectors, miscellaneous accessories,
etc.
Just too many to list here. Please e-mail your requests.

.

Prices do not include shipping from Florida.

Thanks.
