1/4″/6.4mm max Cable Size Chokes

For use with RG-58, RG-6, RG-59, LM-240 and similar size cables – all cable impedances, 160-6 meters. Choke diameter 0.6 inch. Requires 9-1/2 inches of cable for installation of SLO-1/4.Choose SLO-1/4 (5 beads) or for extended choking, choose SLO-1/4-10 (10 beads) or for super extended choking choose SLO-1/4-15 (15 beads).Use SLO-1/4 on RG-6 to stop RFI on cable/satellite systems.


Select chokes with minimum of 500 ohms at your frequency of interest for best results or upgrade to our CUBE(TM), or Super Choker(TM) or Maxi-Choker(TM) chokes up to 10,000 ohms choking

Use on RG-6 coax to stop RFI on cable/satellite systems.

Select 10 bead version for 160 meter use, 15 bead version for even higher choking power.

Snap On and Slip on Feed line chokes available in sizes to fix cables with outside diameters of 1/4", 3/8", 1/2", 3/4", 1" - check website for other size options.

12:1 Baluns are useful between 600-650 ohm balanced loads the impedance at the  end of the feed line is 600 ohms (1/2 wavelength feed line), or high impedance feeds for rhombic,  T2FD and traveling wave antennas.

12:1 Ununs are useful between coax and long wires with a load impedance near 600 ohms like a beverage antenna.  Shortwave listener antennas also can benefit with the 12:1 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.
