EMI RFI suppressor cores chokes

Choke out unwanted RFI (Radio Frequency Interference). These are much better (and cost less!) than those RF chokes sold by a popular company because of the greater surface area to choke RF out of the wire.
The RND-1, RCT-3 and RCT-4 choke snaps over RG-8, RG-213, 9913, LMR400, etc.
The RCT-2 and RND-5 choke (left pic below) will snap over RG-58, RG-59, RG8X, MINI RG-8, etc.
All chokes will accommodate multiple turns of many common wire types
Use these chokes with regular wire of whatever wire is feeding the device being interfered with. Just laying the wire inside the choke is equivalent to multiple turns of wire inside "their" choke. Plus, our chokes cost you less! (Their small chokes are 4 for $15, ours are much cheaper. Snaps on and snaps off, reusable.
Standard "MHF/VHF" mix. Users have reported good results from broadcast band 550-1700 KHz) up through the 144 MHz band, useable DC to 300 MHz.

Suggested uses

snaps on speaker wires, modem wires, coaxial cable, telephone wires, microphone cable, computer sound card wires, keyboard or mouse wires, remote control head wires (especially IC-706, FT-100, etc)
snaps on ALARM panel wires (this works especially good but you should run ALL of the alarm panel wires through chokes), I use multiple chokes here.
Audio video cables, microphone preamps, guitaqr amplifiers, PA system, Hi Fi,
Fluorescent light noise, switching power supply noise.
For tough cases and maximum interference reduction wrap as many turns as possible and use multiple chokes
