F240-31, ID=1.4", AC/DC/Coax Noise Filter, RFI Range 1-300 MHz, AKA FT240-31
Product Details
MPN: F240-31
Country/Region of Manufacture: China
RFI Range (MHz): 1-300 Mhz
ID-B (in/mm): 1.4/35.6
OD-A (in/mm): 2.4/61
Height-C (in/mm): .5/12.7
Weight (oz/gm): 188 grams
Initial permeability: 1500
Case/Box lot size: 100
Frequency (MHz)/Single turn impedance (ohms): 1MHZ: 12 ohms, 10MHz: 40 ohms, 25MHz: 63 ohms

Very useful for AC/DC power, coax cable common mode current suppression. For highest choking resistance, wrap cable through center of ring as many turns as possible. DO NOT use for impedance transformers (2:1, 4:1, 9:1, etc.) - use Mix 43 or Mix 61 for high power.

All F240-31 singles individually labelled with specifications for ease of identification.

Customer Feedback:

At 100 watts on 40 meters, my CW sidetone used to be the smoke detectors in my house! After installing a set of ferrite rings on the 120V and 12V lines, I can finally work 40 meters CW without hearing my code through the smoke detectors. Thank you!

Due to many requests for antenna static bleeders, we have developed a product line of static bleeders for coax and for ladder line applications.  Static electricity is caused by many situations including high desert wind, atmospheric conditions, etc.  You may hear static crashes or have a buildup of static electricity that my be annoying during a radio conversation and it may be harmful to solid state electronics if high voltages are present on the RF input to your equipment.

A static “Bleeder” which shorts the direct static voltage to ground while leaving the RF frequency voltage unaffected if very beneficial particularly to those operations in desert conditions where low humidity, high static buildup are quite common.  The SB-1 and SB-2 coax static bleeders work on coax line and the SB-3 static bleeder is meant for ladder line.

THESE DEVICES ARE NOT FOR LIGHTNING PROTECTION AND PROVIDES NO PROTECTION FOR LIGHTNING STRIKES!!!!!
