Following that logic you then cant reuse tower sections if the galvy has been nicked. Obviously that is not real world reality. And as I have mentioned earlier there are now several speciality coatin
A very basic reason; a local supplier has a stock of 3/4" J bolts and nothing for 5/8". Flange strength is inmaterial at this point if the bolts shear. Very true and by using the TVRO bracket with a

WOW, Ive removed and reused many base plates including a few that were within 100-200 yards of the ocean and never saw one that bad even after 20-25 years. Id suspect a concrete that has a higher con

No and you DO NOT want them sealed; the tower legs must be able to drain. Carl KM1H _______________________________________________ _______________________________________________ TowerTalk mailing l
No difference in construction. Cost decision is yours to make depending depending on which half section you want to throw away when you move. Id personally never buy a new half section. Carl KM1H ___
Just ask K1AR about that some time! He had to get Rohn to build him a shortie "reversal section" . Carl KM1H _______________________________________________ __________________________________________
If you have the room for a back guy why do you need a I beam? The beam should be the height that is calculated the guy wire would be at in a full length run. For a 100' of 45G and not insanely overlo
Something is VERY wrong with those gain figures Dick. Are you adding ground gain? And if the F/B is real Im not at all impressed with either. I could demonstrate at least 20dB F/B and 30-35 dB over 2

I had no problems working WAZ and over 200 countries on the 3 WARC bands during the mostly slow parts of the last cycle with a 160M inverted V with 80/75M inv Vees hung from the same feed which was a
Ive seen it at farms that have either sold to developers or have planted different crops. Drive around rural areas and watch for farms that are irrigating; you usually cant miss the spray towers/head
There are 2 or 3 different size tube top sections. Most hams I know use the flat top section and mount a thrust bearing on it. Big arrays use a second bearing down in the tower about 4-5' and the rot

Adding ground gain was a trick some manufacturers used to inflate the specs in their ads. That led to QST banning any gain claims for decades. I prefer the very basic dBi, then you can toss in the ex
