Ferrite Interference

Ferrite Interference Choke

Two piece snap-together assembly wraps around coax. Removes RF from outside of cable. It is possible to make 2 or 3 turns of smaller coax. Several chokes will isolate end of coax for balanced feed (balun). Useful on mic leads & computer cables. Excellent for reducing RF on a mobile linear's +12V lead. New low pricing. Limited to stock on hand.
