I wouldn't rule out the Aluma Tower made in Florida. The easiest installation I have been involved with. i have the HX50 which is 50ft and a SteppIR 3-element with 30/40 meter added wind-load and have yet to see any swagger even in very high thunderstorm winds of around 50 MPH. No guys and built very well. Good luck on your final selection. 73de Ron W4LDE
