Spiderbeam Balun 1:1 (fully assembled)
A903
High quality W1JR type coax choke 1:1 ratio, 2000W balun for 3.5 - 28 MHz
This is exactly the same balun as used in our Spiderbeam Yagi antennas: a W1JR type coax choke-balun with extremely good balancing properties on 10 - 28 MHz and quite good balancing properties on 3.5 - 7 MHz. It is well suited as a good all-round balun for all 50 Ohm antennas in this frequency range. It uses high-quality components (Fair-Rite ferrite toroid, Teflon-insulated coax cable, rugged UV resistant plastic enclosure).
Note: all parts for building this balun are included in all of our Spiderbeam Yagi antenna kits.
We are offering it here as a high quality stand-alone product for any other 50 Ohm antenna you may wish to use it with.
