Baluns and UnUns


     I fabricate various baluns and ununs to match the impedance of various antennas to the 50 ohm coaxial cable transceivers require.

I can custom make various impedances for a balun to suit your project, email to discuss your needs.

I can also double the toroids or order larger ones to meet your output power requirements. 

If you just want to buy the completed Baluns or UnUns and add your own wire, here are the prices:

4:1 Voltage Balun rated at 700 Watts        $58

4:1 Voltage Balun rated at 1400 Watts      $72

4:1 Current Balun rated at 1000 Watts      $69

4:1 Current Balun rated at 2000 Watts      $99

9:1 UnUn rated at 400 Watts                     $58

I sell completed, ready to hang antenna systems as well.

You can buy one of these antenna systems from me, completely fabricated and ready to hang:

Type                Covers                   Approximate Length     Price (Includes USPS Flat Rate Shipping in the US)

OCF Dipole   160-80-20-15-10-6            254'                    $149

OCF Dipole    80-40-20-15-10-6              127'                    $102

OCF Dipole    60-30-15-6                        87'                      $82

OCF Dipole    40-20-15-10-6                   65'                      $82

End-Fed Longwire 160-10m                   125'                    $102
(Includes 9:1 balun)

(Note, the above OCF Dipole antennas are made with VOLTAGE baluns, they provide better bandwidth.)
If you would rather have a CURRENT balun for your OCF dipole, add an additional $25 to the antenna price.
