Topband: Common mode choking of beverages

  My experience, I have short BOG with a 230 foot CAT5 feed line. I use it mostly for AMBCB receiving.
Signal strengths are good, S9+ on night time 1000 mile away stations. Daytime reception is also good.
But I have no comparison to Coax. My common mode chocking is, "I've been told unconventional", "probably
doesn't work", however my feedline doesn't pickup AM stations, so if my BOG has any directionality,
the feed line doesn't alter that.
  I tested Coax against a twisted pair, twisted pair had much, much, less signal ingress. I was told "coax
doesn't have ingress" and "you must have had bad coax"  maybe...
