Hi Guys, I got a few emails asking where I got the insulated base. I made it. The insulated legs on the market are pretty expensive, and I didn't like that they are in tension and compression when th
Hello All, Thank you for all of your questions and suggestions. The fluid characteristics of plastics was what scared me about the commercially available tower leg insulators. Like the fellow's mobil
I must be a heretic on tower building. If I were an engineer, I'd probably still be designing my first tower. I can see stress tensioning the guys on a 600' commercial tower, anyone can, but on 50' o
Anecdote is a single occurrence. 15 is approaching empirical evidence. I just think the engineers and lawyers at Rohn went to the utmost lengths to protect their own buts. I would too if I owned the
Rather than all of the coring and hammerdrilling, just buy a 3" PVC conduit 90 and a little pipe. Give it to the concrete guys while they are forming up the basement walls and have it poured into the
You need to take a look at the Tennadyne T-8 log periodic. I have 8 towers and have run most every antenna design at one time or another and it is one of my favorites. 5 bands, cw to ssb (try that wi
The Log gain is more like a 3 el yagi, I haven't used a Mosley or M2 log periodic, so I'm not familiar with their weights, but the T-8 log was very easy to lift to the top of the tower when compared
The T-8 is 8 sq feet wind loading and 53 lbs and 754.00 dollars. The Step IR 3el is 6.1 sq ft loading and 51 lbs and 1519.00. AB5GU _______________________________________________ ___________________
Hi Gene, That is exactly what I did. I weighed each parameter, then put up 8 towers and bought a lot of antennas and weighed them against each other. There is a ton of information from hams on which
Hi Gene, That is exactly what I did. I weighed each parameter, but the results were inconclusive. So I put up 8 towers and bought a lot of antennas and weighed them against each other. I found out th
Good luck is right. Houston uses the Universal Building Code, a revised version just for this one city. You have to buy the code book, then buy the Houston addendum to the code. Should only cost a co
The people at the Nebraska store are great, not so much at the california location. de ab5gu _______________________________________________ _______________________________________________ TowerTalk
Thanks for all the replies. The tower needs to go up and down to avoid neighbor issues. Since I mostly only work at night that's when it will go up. The coax needs to be buried to avoid the lawn mowe
Hi Guys, I know this is a bit off topic, but there are some pretty smart guys on this list so here goes. I'm hooking up an Orion 2800PX rotor controller to my computer today. The DB-9 ( OK, I already
Whenever I pour 25G tower into the concrete base I drive a 10 foot section of galvanized plumbing pipe up each leg first. It's cheap and really stiffens up the tower when you climb it. I'm sure there
1. Remove the allen screw 2. remove the ball bearings one by one through the hole left by the screw. 3. Now the bearing halves will come apart. 4. clean the races and ball bearings with brake clean.
Unlubricated bearings? Maybe the reason you are wearing out the races. I use Moly grease on all of mine, no problems yet. Every bearing needs lubrication, even old windmills from 100 years ago have o
