Snap On Sleeve Choke - 3/4"/18.7mm cable


Snap On Sleeve Choke - 3/4"/18.7mm cable SNO-3/4-5

Use for 3/4″ Cable LDF-4, Heliax(R), LMR-600, etc.

Use five split beads for 80-10 meters (3-30 MHz) or ten split beads for 160-10 (1.8-30 MHz) meters or use 15 split beads for even higher choking for 1-10 MHz.

Typical Impedance per split bead: 10 Mhz: 50 ohms, 25 Mhz: 95 ohms, 100 Mhz: 195 ohms, 250 Mhz: 322 ohms

A minimum impedance of 500 ohms is needed for 50 ohm cable or 10 times the cable impedance for other cables.

The beads clamp to the cable and may be operated as is for indoor use. However, it is strongly suggested that they be covered to protect the plastic covers from weathering – use electrical tape for best results or heat shrink to ensure longer life. All kits come with instruction manual which covers assembly and application tips.

As you can see from the impedance vs frequency graph, you can very

effectively increase the choking impedance by increasing the number of

beads on the cable.
