30-2570 - Outdoor Balun Transformer 300 Ohm to 75 Ohm
Outdoor Balun Matching Transformer
This matching transformer is used to connect your 75ohm coaxial cable to the common 300 twin style connection on many outdoor antennas. The CM 94444 is an industry standard balun which offers excellent matching and low loss.
I have used MCM for many years and would give high recommendation for getting the job done right.
