Referring to K6NA's comments on Rohn and Triex tower construction, and my previous comments about Rohn tower twisting under compressive load.... Hi Mike, Don't lay awake at night worrying about this
Big snip Thanks John!Sure hope we don't have a major debate on it. The Rohn position is very informative and interesting. I agree that the six guy solution is far more effective. I received several c

Hi Roger & All, I agree with all of what Roger said, with one exception. Note 4 on the 45G guying diagrams says the designs include 8.0 SqFt for side arms. If we aren't using them, we get to add 8.0

Hi Stan, We are in agreement! But I think that all antenna companies have applied a shape reduction factor to their areas. That's a guess on my part. There is an EIA spec, RS-409, Minimum Standards f

Hi Lee,Many towers work just fine without the TA25 assy. My opinion is that it depends on what antennas are mounted on the tower. The mass and size of the antennas and rotator acceleration/decelerati
