.75″/19.5mm max Cable Size Chokes (includes beads and shrink wrap)

Model SLO-3/4 family of chokes are for use with 3/4” coax cable like LMR600 and similar cables up to 3/4" diameter – works on all cable impedances (50, 62, 75, 90 ohms etc). 80-6 meters.Choose SLO31-3/4-5 (5 beads) or for extended choking, choose SLO31-3/4-10 (10 beads) or for super extended choking choose SLO31-1/2-15 (15 beads).

Each additional 5 beads is approximately 6 dB of common mode rejection (also 1 “S” unit of noise reduction).

Select chokes with minimum of 500 ohms at your frequency of interest for best results or upgrade to our CUBE(TM), or MC-1-3000 Maxi-Choker(TM) chokes for higher common mode noise rejection..

Select 5 bead version for 80-2 meters use; 10 bead version for 160-6 meter use, 15 and 20 bead version for even higher choking power on 160-20 meter frequencies. Power rating is same as coax cable used power rating.

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.

The 5 bead, 1/2" model was previously part # BA-8

Wanted to let you know that I was having a problem with RFI on 40m, but immediately after installing your Slip On Coax Feed Line Choke -1/2"/12.7mm cable, 1.8-300 MHz on a new RG-213 jumper between the IC-9100 and tuner, IT WENT COMPLETELY AWAY!

50 ohm coax to 75 ohm balanced output baluns are useful for low (< 1 wavelength) dipoles exhibiting 75 ohm characteristic impedance or for matching to balanced ladder line whose endpoint impedance is near 75 ohms.

50 ohm coax to 75 ohm CATV coax connections are easily done with a 1.5:1 unun with SO-239 connectors on input and output.  Likewise 50 ohm coax to unbalanced verticals or loads near 75 ohms can be matched with a 1.5:1 unun.
