Q for the CB guru's...?

Okay, I've got a good 102" whip antenna on the rear of the Zuk . Being mounted on the rear tool box carrier makes it a bit high , like over 12' . Of course, the bank drive-through is out of the question since it's trying to tear off their awning and makes a helluva racket . So, here's my question-

How can I isolate and tie the tip of the antenna down without hurting performance ? I remember the old squad cars back in the day, that's how they had theirs and they seemed to work very well ...

I have the capability to machine a piece of nylon block and make a mount , but are there any rules or parameters for location/length for doing this?

The 'Eye' end of a rubber tarp strap should do the trick.
Rubber is radio neutral, and not enough of the antenna is exposed to it to affect your radio.

Tarp strap will also allow the antenna to move around some if you manage to bang it into something...

I'm assuming you already know that whip is mostly for looks, a good wound fiberglass stick antenna of about 4 feet would be plenty and work much better.

Wilson makes great antennas, but their whips have a load half way up, and the good Wilsons are stick antennas...

I've had glass antenna's before, and broke nearly every one of them due to tree branches and such . This was the reason for the 102", it's just a whole lot tougher . On the trail though, the thing can be downright dangerous if held down by a tree branch then suddenly released . Always have to keep an eye on bystanders and that whip since it could nearly sever someone's head if loaded properly .
The strap idea is great , just wondering how it would affect the signal and load back to the radio .

The propagation pattern is affected.. but for goodness sake, it's a CB radio. You're not DX'ing.. it's not a HAM radio. Tie it down and you'll be fine. Let it loose when you need better distance. The load's not affected, as it's already tuned. Tying down the antenna won't affect that.

what leve said.. when i used to run one... i just used a piece of coathanger bent up.. when i keyed up the linear i made sure it was loose.. but for just a cb radio... use whatever you can.. keep it a little loose fitting..

Anyway, you should NEVER ground the antenna.
That's why I suggested a rubber strap instead of a coat hanger...

As for the fiberglass antennas, use a spring at the base to solve your breakage problem.
Antenna springs come in 3 or 4 different rates, depending on the weight of your antenna and how much you whip it around...

I usually start out with a lighter spring and slip a piece of heat shrink over it to stiffen it up to my liking, and to keep the grease in the coils so nothing rusts and interrupts my signal...

So, I was wondering, when that antenna gets to whipping around, does it turn that 'Zuk' over?...

I guess I'll just give it a shot , nothing to lose really on a $40 radio . One of these days I'd like to get my old Motorola System 550 fixed and use it , although it's pretty big and heavy .

"So, I was wondering, when that antenna gets to whipping around, does it turn that 'Zuk' over?..."

You know, had that nearly happen once , took the tennis ball off immediately.

I am sure that my whip SAVED me from tipping over on 3 Stage in Clayton one time. We have have joked about it for years. I have made bystanders dive for cover and I keep the trees trimmed around town with mine.
