I've used thousands of feet of the 400 knockoffs (including the Shireen version at c. .35/ft) as well as Times LMR400, and they are all virtually identical, and that includes sweep tests through 2 GH
At low frequencies, dielectric loss is very low, gradually rising with increasing frequency. At some frequency dielectric loss takes over, but that frequency is way above HF. At HF it's all about DC
Make a bolt-on brace to replace what you cut out - maybe a piece of angle and a couple of u-bolts? -Steve K8LX _______________________________________________ ________________________________________
This is a nicely done video. But 1-1/2" guys? That's puny - the little 1000' Motower in Detroit has massive 3" guys! That's unusual though, and was dictated by the load requirements and the area avai
I think it's it's made in Poland and imported by Alpha Radio. I bought one of the first ones available but haven't got around to spinning anything with it yet, but it seems well made. -Steve K8LX ___
Not dumb, but easily solved in a number of ways. One way: Ignoring the guy wire MOP for a second, one way to rig the new 30' section is attach a rope to the *bottom* of the 30' section and run it up
Years ago I used to use V&S in Redford. I notice they are still around. http://www.hotdipgalvanizing.com/locations/redford.html -Steve K8LX _______________________________________________ ___________
I wonder why crane companies keep their cables (on million dollar cranes) lubed religiously? On this particular topic, I would not place much faith in the manufacturer's edicts, unless you're looking
Yes. As someone else mentioned, location will have some effect on optimum maintenance, but at least in rust prone areas, some form of penetrating lubricant is definitely indicated. I can't think of a
For light tower work (up to 1000 lbs load) most crews use capstan rope hoists (catheads). After getting used to one, you will never consider anything else. http://www.midwestunlimited.com/categories/

Well, they do make female F connectors for anything up to .750, but normally it's terminated with pin connectors. The pin connectors though are useful as a starting point to transition to UHF. -Steve
That is the method I always used when I was using CATV hardline. As I recall, .625 fused disc line had the perfect sized center conductor for a UHF barrel. With .750 cable I had to file down the cent
Does anyone have a good idea of minimum bending radius for the 1/2 inch cable TV hardline? I have been told anything from 5" to 50". I believe 5" is way too sharp but 50"??? I sure that 50" would no
I recollect that the minimum bending radius for all coaxes is 6 times the diameter. For 1/2" RG-8, that'd be 3 inches. I think that's for coax with braided shield (the RG-8, RG-213) kind. It's an An
You probably have Commscope P3 500 or something very similar. Here are the specs for P3 500: http://www.tvcinc.com/downloads/CommScope%20P3%20500-2.pdf Minimum bending radius is given as 6". -Steve K
That's a bit of over-generalization. Both RFS and Andrew make standard and flexible versions of their cables. The construction is virtually identical on comparable versions. corrugated center conduc
I'm having a problem where one of the cadweld one-shot doesn't have any of the igniting powder in it. From what I've gathered the main powder material needs a very high temperature to ignite. So far
IME, in a typical zig zaggy trench with less than optimum corner bends and dirt that insists on getting into your glue, and a myriad of other defugalties that aren't anticipated while drawing it all
Fine, as long as the ginpole can be counted on to handle the extra weight. As others have implied, there is no good substitute for adequate headroom, yet just getting a longer 2" aluminum tube isn't
