For impedance transformation/isolation applications when max power is < 10 Watts PEP, this transformer provides a simple interface between transmission lines with different connectors or impedances or simply common mode isolation. DC continuity for bias-T applications.
1/2″/12.7mm max Cable Size Chokes
Model SLO-1/2 family of chokes are for use with ½” coax cable like RG-8, RG-213, 9913, LMR-400 and similar cables up to ½” diameter – works on all cable impedences (50, 62, 75, 90 ohms etc). 80-6 meters.Choose SLO-1/2 (5 beads) or for extended choking, choose SLO-1/2E (10 beads) or for super extended choking choose SLO-1/2SE (15 beads).
Select chokes with minimum of 500 ohms at your frequency of interest for best results or upgrade to our CUBE(TM), Super Choker(TM) or Maxi-Choker(TM) chokes up to 10,000 ohms choking.
Select 5 bead version for 80-2 meters use; 10 bead version for 160-6 meter use, 15 bead version for even higher choking power on 160-20 meter frequencies. Power rating is same as coax cable used power rating. Protective heat shrink included with beads and instruction manual.
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
The SLO31-1/2-5 is the new name for the old product name BA-8-5, the SLO31-1/2-10 for BA-8-10, etc.

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!
