Description

B1030C-5K BALUN 1:1 (50:50 Ohms)

This Current type BALUN is the perfect replacement for your Yagi antennas with a boom of 2″ (51mm) diameter.  It covers 10-30MHz and will be perfect for any single or multiband antenna such as Yagi, Quad loops, Navassa-5, Cushcraft A3S, A3W A4S with add-on kits, Hy-gain TH3, TH5, TH6DXX, TH7, and TH11 or any WARC multi/single band antenna. Our BL1030C-5K has huge Resistive values of Common Mode Choking Impedance from 14-54MHz of HF spectrum, it even covers a 30m band with over 5000 Ohms choking impedance, click the chart in the image gallery for actual measurement data. Unlike other companies, we do not claim unrealistic impedance values or frequency coverage. Most important, the value of Common Mode Choking Impedance and it’s Resistive (Rs) part is always higher than Reactive part (Xs) over the working bandwidth. This parameter, Rs>Xs ensures that your antenna will be balanced and your coaxial cable will not become part of the radiator and destroy radiation pattern and front to back (rear) ratio. To further improve your antenna system, add complementary CMC-230-5K on the other side of your feed line to reduce induced common mode currents and suppress noise from various sources.
