1. [TowerTalk] Common Mode Choke Locations (score: 1)

I seek a better understanding of the proper application of common mode chokes. First, the setup: I have several coax-fed antennas on a crank-up tower. The coax shields are bonded to the tower at the

The only location where I use a choke is at the antenna feed point. John KK9A The questions: I realize that the bonding and lightning ground system isn't an RF ground, but I wonder if it influences t

I'm not trying to promote choke overkill, but look at it this way. If it is a truly high impedance CMC at the antenna, the shield of the remaining coax run to the shack is essentially a receiving ant

Since my current antenna situation is a far cry from ideal (and far from what it used to be), I run a common mode choke at the antenna feed point and one at the radio end of the coax for exactly that

If grounding and bonding is properly done, cable shields should be bonded to ground before they hit the operating desk. If adding a choke at the shack end of the feedline reduces common mode current

I always place a choke at feed point, and a second one at the other end of the feeder, at the radio shack. Both ends of the long coax got a choke. 73, Maximo EA1DDO <http://foro.ea1ddo.es/> The only

What works for me - ie I hear better than talk even with 5+5 yagis and big towers at QRO. But that is not definitive since I can only guess at the noise/QRM situation at the other end. OTOH, #31 chok
