If you have good soil, good guy anchors, and zoning isn't a problem a dirt base works just fine with a 40 foot tower. ROHN even used to make one. As an educated guess, I'd say that only about one out
I can only tell you what I've done in the past. I'm not a professional, but I've been climbing for many years and had to do so at work as well. First you do a thourough visual inspection of the tower
True as many even set in concrete may not have proper drainage. But ...ROHN doesn't even want the bolt holes, which will be too small, reamed or drilled out as it'll break the galvanizing which leav
As did a bad back and stroke for me, but I do expect to be back to climbing in the not too distant future I've had the rotator ready to go back in for over 6 months and the big array has been held i
I'd rephrase that and say the bottom of the base sections sets *in* the top of a 6 to 8" layer.That keeps the concrete from flowing down and around the bottom of the legs. Usually you have to use a
The distance is really to provide the proper angle so base you distance and I-beam height on that angle. Roger (K8RI) _______________________________________________ ________________________________
I saw one answer that said that is *not* the way it is done. I have never seen a tower designed the way you describe. They are all the other way around. The larger tube or bell on on the upper secti
Common writting practice dictates that normally all acronyms are explained the first time they are used. I follow Aviation, Astronomy, Amateur Radio, and computer news groups. The same acronyms may
I just go down to the local hardware store and get motor starting caps of the proper value. The AC voltage rating on them is usually so high that is a non issue. 73 Roger (K8RI) _____________________
As I recall each section is stepped at the top so additional sections would get a little smaller with each addition. I've never seen a straight section for those. That's not to say they don't exist,
Maybe that is why I've seen so many Aluminum towers up here in the frozen north that have split legs from water getting in and freezing. I never noticed them to have this type of joint though and can
It's surprising how quickly we can get used to doing things that most others consider dangerous, or probably it would be better to say they wouldn't consider. Roger (K8RI) This link was posted a whil
Most years we have used one or the other of two high school stadiums for our club FD sites with the grand stands serving as support for towers and the "press box" the location for at least one of ou
Here we have a ham station in both the EOC and mobile EOC van purchased by the county. During emergencies officials get "shadows" for emergencies if the regular communications fail as well as a seco
I agree with Gary. it isn't going to hold any load, just have the splits welded and use it for a vertical. You can even reshape some pretty bad splits with a hammer so they can be welded if you are c
Even "remote" doesn't come with any gurantees. Purchase 20 acres, set up a remote with antenna farm, developer sells land around you, large group of fancy homes go up, form a HOA of which you aren't
And in that case I could probably be bought if the price is right<:-)) Roger (K8RI) In the situation you describe, you can sell out to developers for a boatload of money and then go buy any QTH you w
It's nice to see some one use the good stuff in "tight places" instead of the regular caulk. <:-)) Roger (Use to work for that company) (K8RI) _______________________________________________ ________
Sure they do. BUT... Finished antennas take lot of space, cost money to produce, and if they are in stock at inventory time the manufacturer has to pay tax on the finished product rather than the st
But many states do. MI and many others charge personal property tax or the equivelant on inventory. This can be 30 mills or more. It doesn't sound like a lot, but inventory can add up in a hurry to
