Has anyone found an appropriate spring for protecting dipoles when the supports such as trees sway? Maybe a name hardware supplier has such a spring? I am going to use Dacron with a strength of about
I've used a garage door spring on my 80-meter dipole for about a decade now. Seems to do a good job, although I have plain old #10 copper wire so it's possible I now have a 90-meter dipole.... My loc
Hi John... Here's a pragmatic approach to spring selection... 1. My support lines are rigged right over the tops of the trees... up high where the branches are slender (1/2 inch diameter range). At t
I would use a pulley attached as high as possible in the trees and have the rope attached to a weight that will supports the antenna. I would think that with the correct weight you would not need any
I used old garage door springs. I contacted a few garage door repair/install companies and they were happy to let me have a few old springs they had in their truck. I look for those that have more "g
Check out the latest QST. There is an article about this subject. The author uses a piece of pipe which has a concrete at the bottom. He pounded in a ground rod and then slides the pipe with concrete
John. I use in lieu of the "hanging weight and spring", a 4' heavy duty solid rubber tie-down or bungee, whatever they are called, on the ends of my 160m, 80m and 40m inverted V's. They have been up
Let's see; at ~$40,000 for a small city lot, the Vee beam using perhaps 15 lots (?), that is about $600,000--lots of pennies!!!!!!!!!!!!! k7puc _______________________________________________ _______
Far be it from me to criticize something in QST, but that thing is a foot hazard. It'd be better to have an external housing for the weight, and if either sort of guide becomes misaligned for any rea
What is a good antenna that I can feed fron the end. I have some tall trees far apart and would like to run a a wire between them up 70ft and not have the weight of feedline in the middle since there
The good old End-fed Zepp works wonders. Uses open-wire feedline and a tuner for same. Lots of info about it in Antenna Handbooks. Don N8DE _______________________________________________ ___________
Hi Monty Have to agree with you on that one. I have a 160 meter inverted L up in a tree, and where it hooks to the bottom secure point, I have one of those black rubber bungy-like things holding it.
Hi Jack I see someone already answered you on this one, but the end fed zepp is a winner. It works best if you have a open wire tuner, like the old Johnson Matchbox type. I worked a bunch of countrie
