MINI-BALUN Features:

- Uses proprietary Multi-Turn ferrite technology for maximum choking (up to -38 dB common mode noise rejection) and maximum bandwidth

- 500 Watts PEP, 50 ohm SO-239 connectors In, Dual Side Stud Output, 1.8-61 MHz (usable to 100 MHz) - AKA 1:1 BALUN

- Works for all coax fed antennas from 1.8-61 MHz (160-6 meters) - excellent for multi-band beam interface, G5RV/ZS6BKW or Flag Pole OCF antennas fed with ladder line.

- 2-5 times more common mode noise rejection, wider bandwidth and higher power then competing isolators

MINI-CHOKER feed line chokes are used to suppress common mode current carried on the outside of the coax braid which is often responsible for receiver noise and RFI in the receiver/transmitter. These chokes are very useful for suppressing RFI common mode current at the antenna feed point, at 1/2 wavelength intervals along the coax feed line and also at the entrance to the radio station.

This choke has a SO-239 input and 1/4" top studs output.

For Higher Power needs use our MAXI-CHOKER with dual stud outputs in 1.5KW or 3KW version part# MC-1-1500LL, MC-1-3000LL

If you need a unbalanced output (SO239 output) instead of a balanced stud output, see MC-1-500 with SO239 output and input..






16:1 Baluns are useful between 750-850 ohm balanced loads where the impedance at the  end of the feed line is 800 ohms (1/2 wavelength feed line), or high impedance feeds for rhombic,  T2FD and traveling wave antennas.

16:1 Ununs are useful between coax and long wires with a load impedance near 800 ohms like a beverage antenna.  Shortwave listener antennas also can benefit with the 16:1 unun and it may provide a better match than 9:1 ununs – this means quieter noise levels and stronger signals so you can hear distance stations easier.
