I've done the normal extensive "back issue" search and came up needing more. As soon as the weather climbs considerably from this morning's single digit temperatures, I'm going to start digging holes

I don't know the two different sets of charts you are referring to, but I can comment on the "proj. area". In the newer Rohn book, in the drawings, each tower configuration (wind speed and tower heig

That's a good point. Considering you can buy a short, used Rohn 25 AND a tribander for about $250, another $250 for a rubber stamp doubles the budget. And $250 is almost 10% of my planned 100' Rohn 4

FALSE!!!!!! Don't even thing about it! Speaking in rough numbers, Rohn 25 will hardly handle 70 MPH winds at 40' self supporting, with ZERO antennas. With any antennas at all, it would fold over. --
