Add to cart
  • Description

The same balun as used in our Spiderbeam® yagi antennas, a W1JR type coax choke with extremely good balancing properties on 10 - 28 MHz and quite good balancing properties on 3.5 - 7 MHz. It is very well suited as a good all around balun for all antennas on this frequency range.

Facotry assembled, ready to use.  Only high quality parts are used.  Fair-Rite FT-240-61 ferrite toroid, Teflon coax cable, rugged UV resistant plastic housing.


This balun is already included assembled in all of our Spiderbeam® yagi antennas sold as factory assembled.  We are offering it here as an accessory item for using the 40m add-on dipole kit with a separate balun from the main antenna feed or as a quality standalone product for any other antenna you may build.

Maximum power:


For antennas with an SWR under 3:1 - up to 2000W
For antennas with an SWR over 3:1 - up to 1000W
