isn't this one of those things where you want to be using some numbers? I can't imagine that you want anecdotal info here on sizing. Like how much tension do you have withstand? Depends on your tower
There's a lot of variance in rivets, beyond material and mandrel material. I like the Avex rivets, because they handle a wide grip range, and not too expensive Don't need a lot of different grip leng
the ability for a solid block foundation to resist overturning is mostly dependent on the area of one side. So comparing volume is misleading, if you are willing to believe you have sufficient soil f
I would question whether the "special use" requirement is really valid. Since they didn't know about ham radio, how can they be right that it's a "special use" ? looking at the city of martinez (your
Jim made a lot of good points Jim mentioned "Perhaps that's why hiring a professional up front is worth it? They'll know the local processes, know what is special and what isn't, and know the right a
Yeah it's instructive to see how contractors deal with the permit process. I think the first thing is to accept that the permit process is not about helping you do a good job. You have to manage that
I use it. I paid for a key, but that doesn't get you any different software. Yagi Mechanical uses Java. I notice in March, he switched to checking your Java version and only installing if what you ha
With a small 52' crankup, you can probably live with quite a bit of lean. The main problem is whether it can still go up and down without binding. The additional stress on the tower from leaning a li
The last time I replaced the bearings, I just used McMaster Carr. I believe I used the SAE 841 oil impregnated variants which spec a 0 deg F min http://www.mcmaster.com/#bronze-sleeve-bearings/=ciyy
interesting question. No one really addressed how to come up with the length of splice. If this was a normal bolted joint, you might say something like 8-10x bolt diameter for spacing and end spacing
Well, I have an answer/existence proof, but you might not be comfortable with the execution: I have 3 rotator computer control cards. The first is your case. g800sa controlled by ez-rotor-control kit
screening... "Steel is a very poor conductor at RF" Looking at VK1OD's table here, zinc is pretty good http://vk1od.net/antenna/conductors/loss.htm so zinc-plated steel, or Al would be fine, it's ju
I notice that the people doing underground electric fencing seem to favor polyethylene insulation, with galvanized..they seem to agree that you need more than the galvanized for protection. I don't t
This can't be right: "I probed a bit and he said that the design depends only on the shear strength of the bolts, not the clamp friction. So, as long as the bolts don't fall out they should withstand
since we're talking yaesu, I'll throw something out in case someone can help. I'm shotgunning this debug, but maybe someone has experience that can help. I have a g-1000dxa controller that had two pr
Look on Ebay. I had one shipped to me from China, pretty quickly, with 5 meter USB cable (some have 7 meter) for I think it was $30 or $35. They have LED light source on the camera end. I got one tha
Value is what someone would pay for it. I can't imagine another ham paying more than $10k for any existing used tower setup (which is probably in very used condition) on the other end, it might be wo
sounds like you're not going to back guy the power pole? don't say how high it is. if the pole is only 6' out of the ground, the pulling force on a single wire winch is probably 1500 lbs or so. That
a well designed antenna launcher is great. A bad one is frustrating (intermittent, non-consistent launch). There's a huge difference between a home brewed one, and one from a purchased kit that has s
I put up a G-800 in the last year with a lower mast clamp. If I remember right, I had to swap out the bottom bolts that came with the G-800 with longer bolts, when the mast clamp was used. I had the
