Hello 211 in the Mag, Bobby:



I have seen a lot of guys mount the antenna on a pipe or mast to get the antenna above the tree's so that the trees will not block the signals to the antenna. And again ground the Coax coming down the tree.

Default Imax 2000 in tree

Hey all, i have never done this before but would like some input on this. I have a buddy who is going to get a Imax 2000 and wants to put it in or on top of a 80 (or better) pine tree. What all does he need to perfom this action to see max results. Thanks <img src=http://www.ezboard.com/intl/aenglish/images/emoticons/grin.gif ALT=" >D">

He is going to put it at the top, no branches in the way if so they wil lbe cutt down, what do you need to get t oput it in the tree securly and what measures in every aspect needs to be taken step by step, he wants to do it right (im not going to do it, no way ). Will like a chimney mount work well with like a 4 foot pipe? What is the proper way to ground that sucker up there?

'211',

Any way you can think to mount the antenna should work as long as it's mechanically 'sound' (won't fall out of the tree). As for grounding, run an appropriately sized wire down the tree to your/his ground system. An approximately 100 foot ground cable will necessarily have to be larger than 'normal'. What size? Beats me, what does he have handy?

There's really not much attenuation from trees at HF...

Bobby,



Don't know if this will help or not but take a look. CDX-787 base The mount made it easy to push the antenna and mast up higher in the tree. Leave some slack in the u-bolts. It will allow you to push the mast up and then will lock against the mount when you repostition to make the next push. Once in place you can attach a ground wire and crank down on the u-bolts.



Hope this helps!

Chimney straps are not the best idea, as it may kill plant material above the strap. Think of a tree like your arm: If you put a strap too tight onto your arm and leave it there, it cuts off the circulation. It's a rough analogy, but you get the idea. If you want to use a mast, I would get a lightweight mast, attach the mast to a plate with some U-bolts, and then use 4 big lag screws and go directly to the trunk. The tree will heal around the lag screws and it should be pretty solid.

Hello Bobby:



I agree with Moleculo there, about NOT using Chimney Straps on a tree.



I have used rope and whet ever was laying around to that the tree could grow while holding up the mast.



The coax needs to be connected to a ground rod as it comes down to the ground to attenuate static, and offer some protection to Lightning. Or a first class installation, have a Lightning Arrestor connected to the Groung Rod, having the coax connected to the Lightning Arrestor.



Heres a web site for a Alah Delta Surge Protector:
