I've got my 190' R80G tower guyed with Philly, and I've been assuming that this system will outlast me. What did I miss? Now I'm I'm a-scared. As far as cost - did you figure in your labor cost on br
I lean toward mounting rotators a little further down in the tower, even just 2 or 3 feet further down. The top spot on R25 has no diagonals and it's a very weak point in any install that has much wi
I must have missed the permit aspect, that brings another dimension into it. I was thinking only about strength and ease of installation and maintenance, which is all I ever think about on my own stu
The disconnect method is fine if you're always at home and you're not serious about a contest that might be running or trying to to snag #310 when a storm approaches...but otherwise, it's nice to hav
Right, and then using a relatively inexpensive N to UHF adapter if you need to get to the UHF connector series. Might not satisfy the DIY jones, but it's quicker and cleaner.. -Steve K8LX John KK9A I
I just happened to buy some RF Industries (RFI) NM to UF adapters @ $3.77, and some NF to UF @ $5.77 from Tessco. RFI is good quality IMO, and those prices are relatively inexpensive IMO. YMMV. -Stev
Over the years Valmont has acquired a number of their former competitors including Microflect, Pirod, & SitePro; and pretty much kept and absorbed those company's product lines. It's all top quality
Just a wild guess, but he's probably going to use the 12-2 for the motor leads on the rotator. OTOH, I've got an extra 12-2 with gnd in my low low voltage conduits used as a *temporary* AC supply for
soil. But they still use the 10% of total height + 2 ft rule in either location. Bell, Verizon AT+T ,etc, still use the same format. That rings a bell, I think it's always been 10% + 2' around here
It's actually a good question. Functionally it makes no difference, but from an inventory perspective, it's huge. It's *best*, IMO, to standardize on female connectors on your Main Lines, and male co
Well yes, surge arrestors *usually* are M-F, but usually get attached directly to the main line, so functionally you end up in the same condition. But point taken, there are exceptions to every rule.
My favorite tool for cutting frozen bolts (too big to twist off and break) on a tower is a 4.5" battery grinder fitted with a thin abrasive cut-off wheel. I assume one can purchase such a cut-off whe
Spelter sockets are the ONLY termination on the *larger* sizes of Philly. *Larger* being the sizes that Grant was referring to. And regardless of what typical applications might be, why would anyone
And regardless of what typical applications might be, why would anyone knowingly use a termination substantially weaker than the cable itself? What if If the working tension was significantly less t
Harnesses tailored for rooftop workers typically have no waist D-rings, so they are not appropriate for tower workers or anyone needing positioning lanyards. Of course you can always wear a legacy wa
Fortunately for me I've never needed to work solo, but if I did, I'd be thinking along these lines (if the load is more than you can comfortably handle with brute force): Pull your load almost up to
Terry, Rope grabs aren't all that expensive. The lower priced ones are usually not favored by climbers because they often don't travel downward very well of their own accord. Such as the top item at:
Or add a few wraps of silicone tape on the smaller diameter before heat shrinking over it. -Steve K8LX Fill it with RTV silicone seal before you shrink it. Is there shrink tubing that will reliably s
They only recommend Chrome, Firefox, FWIW, I only use Chrome and Firefox. Internet Explorer is on my computers ONLY because I can't get rid of it. :) I use Firefox, Opera, Edge, and I.E. in that ord
Roger, I'm pretty sure he's talking about threading "dimpled" lock nuts onto the bolts. -Steve K8LX ROHN says to enlarge the bolt holes using a taper pin punch. The punch should leave the galvanizing
