Hi, Bill,
I would add that there is nothing good that can come of having coax pull
away from a vertical without a good common mode choking device of some
sort. You may get away without it, but if not you have lost. Lost dB,
picked up noise, changed pattern to favor noise sources.
If you have
And you don't need a hail-mary super choke for the job.
Hi Guy:
I'm going to try elevated radials on my shunt-fed tower. I was thinking
about constructing an Ugly Balun for the job with 4 PVC and Bury-Flex.
What kind of choke do you use / recommend ? About how much coax should be
wound on the
Just DO the common mode choke on any vertical. Don't tempt Murphy.
1.) He has a vertical with the base 60 feet above ground, and it sounds like
the feeder drops vertically
2.) If the coax is 60 feet to ground, and has a surge impedance of around
500 ohms in common mode (it's a thick
Is there any grid square list file to use with N1MM?

I stand by my comments.
I find after some interesting conversations that readers of posts
often read as if written to them. So I write my posts as to the
general audience. If an expressed situation is so specific as to be
I hear what you are saying Guy.
Every vertical installation is a unique situation.
I dont have enough technical knowledge to determine
when my vertical antennas could do without a common mode choke.
I plan to continue using a choke on all my verticals to be safe.
