spring under a 10k or monkey made antenna

[BOOTY MONSTER]

will and/or how much will putting a spring under those type antennas affect performance and swr ? im looking to protect it incase i missjudge the height of a tree limb ? also......will a spring make them swing in the wind while driving like a 102 whip?

I run a 10K on the left-rear of my Ranger,27" shaft, no spring, works Great.
I agree with the Fish thing, in my case, no spring needed.

springs are for whips. I wouldnt put one on a 10k or monkey. i can understand your concern, but your radiation and swr would suffer a bit going down the road with the lean back.

I have springs on both of my predator 10K antennas, so that when going in parking garages I can fold them over....
they would layback when driving down the road but I have guyed them in place....using nylon zip ties and rubber bungee cords....
they are both mounted on vans at the back left hand corner, about 8-10 inches down from the top of the van ....one single coil and one double coil both with 17" shafts.....
and work great
later

they make some pretty tough springs out there , IM not up on the 10Ks , but I've heard guys say that they are very light antenna's ? even though I have asked numourus times how much a single coiled 10K weighed and never have gotten an answer to this day ? other then someone saying they weighed less then a Wilson 1000's load and stinger which I've found hard to believe. A Wilson 5000 load and stinger weighs 15 oz's total.

hey switch, I have both the 10k and a wilson 1000 and the 10k is lighter than the wilson stinger and coil believe it or not.

if that's the case ? I would like the weight of a single coiled 10K with it's shaft. A postal scale would be close enough. IM sure if the 5000 load/stinger is 15oz the 1000s would be a few oz's less then that.

jim, I will see what I can do. Its unbelievably light. I was skeptical at 1st on the weight until I got one. When I got mine in the mail, it came in a cardboard tube and it felt like nothing was in there.

This is another very old post but, I have an old 1960's barrel spring under my Predator 10K. It's stiff enough the antenna doesn't bend backwards at highway speeds but, I am concerned about accidently hitting a low tree limb. And, the antenna tuned extremely well with the spring.
