Ferrite Snap On Combo Pack

Split Bead Picture 1 - Ferrite Snap On Combo Pack

The Ferrite Snap On Combo Pack is a convenient solution for troubleshooting RFI/EMI with various diameter cables ranging from 1/4″ to 3/4″ for use as either single turn or multiple turn ferrite chokes.   The snap on chokes are useful for RF coax, AC/DC power cables, and device interconnection cables.

Always use a snap on  with a larger inside diameter than the diameter of the cable and use multiple turns if possible (2 turns through the snap on is the same as 4 snap ons with 1 turns). Included in these combo packs are our most popular snap on sizes as follows:

Inverted L antenna with radiator and counterpoise for simple installation - choose 80/160 meters and 1.5KW/5KW feed line choke included inside weatherproof enclosure. Separate counterpoise and ground connections

* Complete package - just add coax

* works single band with ease

* can be configured as vertical or inverted L configuration

* Choice of 1.5K, or 5KW PEP rated choke to suit power needs

After many requests we have created a compact, special interface box with internal feed line choke and separate connections for counterpoises (not grounded) and ground connection. The 1:1 choke keeps RF current off the outside of the coax braid and on the antenna where it belongs. The extra choking action also means that the coax feed line will not act as a radiator causing unnecessary RF interference (RFI).

80 M radiator/counterpoise is 70 Feet (you get 1 each) - adjust length to your favorite frequency

160 M radiator/counterpoise is 130 Feet (you get 1 each) - adjust length to your favorite frequency

Antenna is tuned to you favorite frequency by shortening the counterpoise (roll it up or cur length) while keeping the radiator length constant.

Choose 1,5KW PEP or 5KW PEP options.

1.5KW and 5KW are in 4" x 4" x 2" enclosure. 1.5KW is 3 pounds, 5KW is 5 pounds. 2 antenna insulators are included.

ADD CMNF-1500 (1.5KW) or CMNF-5000 (5KW) common mode noise filter at radio end of coax to reduce common mode noise up to 6 "S" units on long coax runs!
