This Ferrite Ring and Snap On Combo Pack features our two most popular ferrite filter sizes - the 1.4" ID ring for multiple turns of AC/DC or signal cables and the 1/2" ID snap on for signal cables like ethernet, audio, video, coax or data cables. You get 10 of the rings and ten 1/2" snap on ferrites - plenty to solve a complex RFi problem or several smaller ones.

The filters are useful for RF coax, AC/DC power cables, and device interconnection cables.

Always use a snap on or ring 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 turn).

Combo Pack includes the following:

F240-31 ring – 1.4″/35.6mm ID – 10 pieces

FSB31-1/2 – 1/2″/12.7mm ID – 10 pieces

Normal Retail price is $155 for these parts

Portable operation is fun but also brings challenges to the radio operator concerning receiver “noise” levels, RF interference from adjacent sources including close by transmitting stations, and RFI from portable generators.  A typical scenario and some suggested Palomar product solutions are shown in the picture below:

Generator RFI testimonial:

Bob 

Received your order in a timely fashion. Tried the generator kit on Sunday & it drops the noise from S9 to S5 and 
took out all the electrical noise.  I may want some more toroids from you at some point for other interference problems
I have  here.

Make your expedition or portable operation a pleasant and fun outing and remember to take along your RFI kits so you have more time to operate rather then to troubleshoot intermittent or noisy receiver conditions.
