Hiya, Byron --     The proposed configuration sounds good to me but I'm not offering an answer to your question. What I am offering is a tower technique that I highly recommend.     Install the ante

Maybe Im dense, but I dont see how this does anything (much). If the back of both antennas has a larger wind area than the front, the torque on the mast is going to twist the mast in the same directi

I'm with you, Chuck. The torque is additive regardless of which side of the mast the antenna(s) are on. 73, geo - n4ua _______________________________________________ ________________________________

Seems like if the wind is in-line with the booms, there will be a small amount of torque even if the antennas are perfectly wind balanced (if they share the same side of the mast). And that small tor

Guys, I really got to wonder about this. It seems to me IF your antenna load on the tower is a concern, why not just add some guy wires. A guyed tower can handle the wind forces so much better and yo

The discussion is more about rotational torque on the mast and rotator than a worry about a tower falling down. Think of it as an academic exercise. -Steve K8LX Guys, I really got to wonder about thi

I wish that I understood how mounting antennas on opposite sides of the mast cancels their wind load. Also I am not sure how well a single tribander will work at 115 ft high whenever the sunspots ret

I believe that Steve K7LXC is referring to the torque load on the mast and not the wind load, per se.Byron W5FH On Thursday, June 6, 2019 05:45:55 PM CDT, john@kk9a.com <john@kk9a.com> wrote: I wish

I missed the torque part however I wish someone could explain this in simple terms. John KK9A From: Byron Tatum [mailto:bjtatum1@att.net] Sent: Thursday, June 06, 2019 23:03 To: towertalk@contesting.

I missed the torque part however I wish someone could explain this in simple terms. I'll give it a try. Stick a tennis ball on top of a mast. It creates no rotational torque in the wind. Stick the t

It just occurred to me that with a small lever arm and single long boom (which all booms are), equilibrium might occur well before the boom goes totally crosswind. At this point I'm entering the area

FYI... Just seems to me your heading for your beam would have to be so accurate into or away from the wind that it would take a 'perfect world' scenario to have this happen. And doesn't the wind shif
