HI all! I have a PRO57B + 40 on a telescopic tower at +/- 65 ft . I take here an sample: the stronger wind (dominant wind) comes usually at my qth from the west. So, what's the best position of the b
Hi Beaupain, My thinking on this interesting subject leads me to believe that you should orient your beam perpendicular to the direction the wind is coming from... in your case either North or South
Hi Roger...this principle only works well with smaller and symetrical antennas...in practice when you have a long boom yagi...like most computer designed arrays that have the reflector, driven elemen
For years now, I've been hearing all of this jabber about turning your antenna into the wind when the winds blow hard. Well, answer me this. Why is it all the bass fisherman turn their hats on backwa

Hi Rick, Yep! I now stand convinced that no matter how smart I think I am, or no matter how clever I believe my reasoning is.... there's no end to the stuff I simply DON'T KNOW! And even though I'm f
Hi Bob, I confess to knowing nothing about bass fisherman but I like the challenge of trying to answer your question. Turning the brim of the hat "downwind" (towards one's back) probably serves two p

I still head my beams directly into the wind. Based primarily on the fact that is the way they stabilize if left without a brake. Have seen that phenomenon many times. de K4VUD -- FAQ on WWW: http://
OK...what does bass fishing have to do with towers? You would think this reflector would not have this type of humor on it. This type of humor is...well...just....so profound. Lets see here...we have
Hi Charles, fact You make an interesting point. Thanks. My perspective is only from the point of view of a small tri-band beam owner [TA-33] which is almost symetrically balanced on the boom and turn
Great Falls, Montana has the highest daily average windspeed of any city over 50,000 pop. in the lower 48 (Book of lists a few years ago). We get frequent 60-70 mile an hour wind gusts. To clean alu
Hi Charles... and the TowerTalk gang, Thanks for your thoughtful comments. I guess the fact of the matter is... that I simply don't have enough real understanding of all the parameters operating here
Hi Roger, as my first input to TT, I hope this answer doesn't sound short or presumptuous. Do beams have more than one wind load specification? Yes; however the industry assumes that the max. load sp

I meant to analogize a "wind direction indicator" or weather vane, to the beam antenna. If a weather vane turns into the wind, it is because that is the position of least pressure on its parts. Likew
Even a weather vane has a point of least resistance. Have you ever seen a weather vane with the pointed arrow part pointing into the wind? Tom -- FAQ on WWW: http://www.contesting.com/towertalkfaq.ht
Weathervaning illustrates a position of =equal= pressure, not necessarily minimum pressure. Positions of equal and minimum pressure often coincide, but I don't believe there is any physical law that
Hi Steve, K1PEK, and the multitudes, Congrats on your first input to TowerTalk. The "rush" one feels when one hits the "send" button knowing that thousands all around the world are reading [and judgi
Hi Roger, your points are well taken: In a message dated 97-11-11 00:07:08 EST, you write: << I'll try once more to clarify by restating my question.... Is it preferable to turn or park one's beam in
Hi, Roger -- This seemingly simple question about beam parking is surprisingly complex. Making a statment like the above means you've made some decisions/assumptions that may or may not be correct or
Hello TOWERTALKERS One more stab at this subject....... Since the beginning of this discussion, it seems to me, there should have been a separation between PROTECTING your tower / mast from stress, O
