Umm, not really. Towers are typically designed to the TIA-222 Tower Standard so the structure capacity has been calculated by real live engineers for their tower customers. Tower manufacturers are in
Typically when a building department wants calcs, that means they want a PE (from YOUR state) stamped package that includes the calcs and base design and complies with current building regs. You can
below. one. Jeez, I'm not an engineer but it appears to be that that's what it means - you have a top capacity and another for 30 feet down. You cannot add them together. If in doubt, run your propos
I don't have the X7 info but we tested an X9 in our tribander comparison test (<A HREF="http://www.championradio.com">www.championradio.com</A>). They're the same basic design so you'll be able to ma
Greetings, TowerTalkians -- FYI. An interesting question on making a 3L CC 40M antenna and the response is from the antenna designer, Joe, W1JR. This is from the antennaware reflector for discussions
Just wanted to mention that digging a hole like this is potentially DANGEROUS due to side sloughing. OSHA rules (that don't apply to non-professionals like TowerTalkians but are pretty good rules to

The Cushcraft design appears very similar to the 3 el 40 short beam from the ARRL Antenna Book circa 1980. It was 3 elements on a 36 foot boom with the reflector and driven element spaced 23 feet. It
Yes - it doesn't have the loadbearing capacity of other 'soils'. Typically you'll have to have your concrete be more able to bear the overturning and other forces which means you should have an engin
Cell tower owners almost NEVER share their tower. There are some co-location sites but lots of times you see several cell towers next to each other. Non-cell towers are different. Some are dedicated
No, it's not. Please refrain from future similar posts. Since this has got NOTHING to do with tower or HF antenna construction topics, it is discouraged. Cheers, Steve K7LXC TT ADMINISTRATOR
Sure. About 80% of what we discuss has to do with BUYING something so if a TowerTalkian has something for sale that's of interest to the rest of the members (unlike the recent 2.4 gHz advert), I enco
Good question. Per the results of the tribander testing N0AX and I did, the TH7 had the most gain on 15M where the swr was the highest. Cheers, Steve K7LXC
