Has anyone (else) attempted to use a hazer on a Tri-Ex tower having a 10.5 inch face? 73 de Jack - n7oo _______________________________________________ _______________________________________________
Would appreciate input on what typical tower installation team charges would be for a one man climber (40 foot tower) and two men on the ground for a 4-5 hour project. Jack - N7OO ___________________
Another thought would be to drive a piling in and strap your tower to it. Jack --Original Message-- From: Jim Lux Sent: Thursday, October 24, 2013 7:53 AM To: towertalk Subject: Re: [TowerTalk] Thoug
What I did on my 40 ft towers was to hand dig a slit trench about 3-4 ft deep on the far end and lay the screw anchors, securing them with two 4 ft lengths of rebar vertically driven against the scre
Depends on soil composition. Here in the Aridzona high desert country our soil is packed like cement. Thus the depth of the anchor hole doesn't need to be as much as with looser earth. In my case I f
This past week I installed 300 feet of 75 Ohm 1/2 inch aluminum cable TV line to feed a 160 meter full wave Delta loop. Matched the 500 Ohm feed point with a 9:1 balun. Cable was speced at 0.2 dB los

Speaking of myths, one tower maintenance reference made a suggestion that galvanized ground rods were preferred over the copper clad ones when installed in alkali soils. My station is in the SW deser
I didn't screw the anchors on my 82 ft. AB 105. Followed the basic instructions from an old Army tower installation manual. Dug a slit trench at a 45 degree depth and exiting towards the tower. Posit
Is there a rule of thumb compensation for boom to element flat plate configuration? I'm using an inch and a half boom for a 17 meter three element yagi using eight inch square plates. Jack - n7oo ___
