Hi TT I will like to know what is the best coaxial cable to make coax chokes and get the maximum impedance or choking effect , I'm talking from: hard lines , double shield , LRM's, RG-142, R
Hector, Go to the W8JI.com website where Tom has the detailed performance done on the various types of coax chokes and how the stack up with voltage and current baluns. 73 Herb Schoenbohm, KV4FZ I wi
There is some info on rt-213 chokes on my web site at http://www.k1ttt.net/technote/airbalun.html I did not do this work so please don't try to ask anything more specific about it than what is on the
Hector here is the information you requested. The coax wound chokes are self resonant in the measurements and in my opinion will be detuned by attaching coax feed lines and proximity to the boom of a
Only the coil of coax with no ferrite is a VERY POOR choke because it is inductive, not resistive. Inductance can resonate with the rest of the coax in the run and increase the shield current rather
Any choke is inductive. If not it is no choke at all. 73 Peter Only the coil of coax with no ferrite is a VERY POOR choke because it is inductive, not resistive. _____________________________________
WRONG. A proper common mode choke inductively couples loss from the ferrite core. A parallel resonance is formed by the inductance of the winding (the wire passing through the core) and the stray cap
