The concrete didn't have a tower attached to it after two days. It was two days for the backfill. Great video! Chris KF7P A lot of the smaller installers use the screw in anchors (AB Chance, etc.) be
Likely you actually broke the tab long, long ago. It was only hanging by a thread, and that gave the separated parts time to rust. This recent lowering was what finally did it in. Definitely call UST
I don't think anyone has mentioned this possibility: Fill in the existing hole with weld and start over. Chris KF7P _______________________________________________ ___________________________________
Yeah, it came back from the dead. Can we please re-bury it? No more responses! Moving on...... Chris Holy Crap! This is a zombie thread from early September. I long since declared my undying love for
This topic reminds me of a story.... Dear Sir: I am a bricklayer by trade. On the date of the accident, I was working alone on the roof of a new six-story building. When I completed my work I discove
What scares me about using a winch with a remote control is having the remote break, get stuck, or otherwise fail to stop winding in cable. Then the tower gets pulled down with you on the top! Chris
Thanks for the plug Kelly.... I have free shipping until later tonight on everything on my website. That $1 difference would get eaten up pretty fast in shipping. Order now! :-) Chris KF7p (www.kf7p.
Gang, Does anyone have any remnants of hardline laying around ? I'm looking for some 7/8" and 1/2" , say 2 to 3 feet of each. I want to use them for some test fitting / mock-up's. Happy to pay for sh
Thanks everybody, I think I've got what I need at this point. We have a good group here! chris Kf7P Gang, Does anyone have any remnants of hardline laying around ? I'm looking for some 7/8" and 1/2"
Did we ever come to a conclusion as to whether or not a flat sheet (like 1" thick or more) of HDPE plastic would work? Sandwich the sheet between the concrete and a flat bottomed pier pin type base.
Hi Vincent, They don't use sheetmetal screws anymore; they use machine screws and nylock nuts. The sheetmetal screws were used a LONG time ago. Perhaps your second hand model is one of these old ones
Steve and Ward's Tribander comparison book is the closest thing we have. Too bad it's so much work to set up a fair antenna test range; I would love to see dozens of antennas compared. Of course, it
Scotchbrite pads and WD40 (and elbow grease) work really we ll for cleaning aluminum. Roger, I believe you, but you are the only person I know who's had problems with nylock nuts. I think you got a b
I'm not in disagreement with you Jim, but then why doesn't NEC specify to do things for lightning protection such as commonly followed by nearly all commercial tower installations? Such as multiple g
Backfill with bentonite or similar conductive earth material. I know a local installer who puts up broadcast towers who did this and created a ridiculously low resistance ground network on a rock mou
It is available under the brand name "Ultrafill" from Harger, in 50 pound sacks. I can get it if anyone is interested. Chris KF7P _______________________________________________ _____________________
Was the brochure released on April 1st? Chris KF7P Around 1980 Tri-Ex apparently offered a tower that came in 10 foot sections and was made with something called Triexium. The data sheet (which says
Why not get a hold of someone at Rohn, and send them one of your bolts and nuts so you can get on the same page? At least you'll know if they are all that tight or if there is a defect. Chris KF7P __
YES!! firsthand... W7HPW's original four square of 3" (or was it 4"? can't remember) irrigation pipe came down about six months after it went up. All four of them. They got some kind of a resonsance
