That probably doesn't mean much, because towers and well insulated antennas charge just from a modest dry breeze. If someone walks back by the creek and touches the insulated tower there, even on a clear day, there is a good chance they will get knocked pretty hard. I think the real tests are: 1.) It is very well established that the highest and most pointed antennas or structures have the most p-static by far. Usually any lower antennas, even those struck from a side angle by the same precipitation, are usually dead quiet or very low noise. If the charge was carried by particles, it would be the same or similar on all. It isn't. The difference in noise of antennas indicates it isn't normally particle charge. 2.) Even without moisture or particles, inclement weather or even dry winds bring p-static. No particles, yet the static occurs. This indicates corona to the air. 3.) P-static normally vanishes immediately following a strike, and then build</pre> Tom W8JI 2013-06-15T17:45:05 http://permalink.gmane.org/gmane.recreation.radio.topband/7611 <pre>It's refreshing to get input from many sources. I always believed that the static was not from a nearby tower as I have three close by. The BOG antenna did not hear the noise, but other antennas did. In broadcasting it is known dry, high speed blowing snow can cause dangerous voltages on an antenna. The first key word is dry, second key work is speed. Think Guy K2AV has it close but I can not help but think that rain drops, and snow flakes, due to their speed, carry the charge. But as in the case of lightening the direction can be argued. Guess something on ground has a sharper point than a thunder cloud. Then there are cloud to cloud strikes. Hmmm. The sharpest cloud ? whoa ! I have a phased three in line 80 meter vertical array. Often the rain static is in one switched antenna direction only.. All coaxes hook to a, phase-current, network.

One thing for certain, I have around thirty bare wire Beverages. My bare wire antennas are no more noisier or better than insulated wire in storm, or at any time. It's been this way at multiple locations (in Ohio and here) since the 1970's, when I first started experimenting. What is around the antenna makes a great deal of difference, as does the height. 73 Tom All good topband ops know how to put up a beverage at night. _________________ Topband Reflector </pre> Tom W8JI 2013-06-13T19:29:45 http://permalink.gmane.org/gmane.recreation.radio.topband/7609 <pre>All of my Beverages are made of bare wire, and I certainly have never experienced this. I think there's something else in play here, such as corona discharge from a sharp point, an unintended spark gap somewhere, and/or the antenna not being at DC ground. 73, Mike www.w0btu.com On Thu, Jun 13, 2013 at 10:42 AM, K9AY &lt;k9ay&lt; at &gt;k9ay.com&gt; wrote: All good topband ops know how to put up a beverage at night. _________________ Topband Reflector </pre> Mike Waters 2013-06-13T18:08:09 http://permalink.gmane.org/gmane.recreation.radio.topband/7608 <pre>A morph on the original subject. Rain static on stacked beams on a tower is often reported with this pattern: Rain static on the top beam is high, whereas it is low or non-existent on the lower. Since the upper beam can hardly shield the lower beam from getting wet in the rain, it cannot be that the drops are charged. Even if they are charged at height, while they are falling, they are in constant contact with saturated air and will equalize on the way down. Try to maintain static charge on an object in steam from a hot shower. When high beam yes, low beam no, rain static is being observed.... What is differentiating the two beams is the characteristic of high voltage opposite charges to accumulate charge on the structure which is closest to the opposite source of charge, e.g. sky in this discussion. Thus the upper beam, being closest to the sky on a complex conductive structure (tower and all its stuff) will be carrying the charge. The raindrop is neutral, and at touching, accumulates a tiny charge</pre> Guy Olinger K2AV 2013-06-13T17:59:03 http://permalink.gmane.org/gmane.recreation.radio.topband/7607 <pre> Phase shift is NOT the length of a transmission line unless the line has 1:1 SWR, is lossless, and/or is a multiple of 90 degrees. In a phased array, with equal 90 degree lines feeding each element, the lines cancel out. Phase shift modification between elements caused by the feedlines to the elements is zero. In the Christman system, or any system where lines are not 90 degrees or multiples of 90 and are also mismatched, the two 84-degree lines do not quite cancel each other out. They reduce the effect of each other, but not to zero like a 90 line or a matched line. They do add some phase shift, but certainly nowhere near 84 degrees. Also the 71 degree line, since it is not 90 and not matched, does not shift phase 71 degrees. Adding the line lengths together without considering impedance and transmission line effects doesn't work. It is really a more complex answer that requires looking at the system. Voltage and current are not even in phase, so we also have to know if the element is drive</pre> Tom W8JI 2013-06-13T17:07:50 http://permalink.gmane.org/gmane.recreation.radio.topband/7606 <pre>Jim Sounds like you have a great 40M antenna for filed Day. QRP sounds like fun. All you need now is brats and beer and something to keep you warm at night. ---------------- Right. There's some discussion of this in the ON4UN book, where I found the Christman matching. As published there, it's 84 degrees of 50 ohm line in each element, plus 71 degrees of 50 ohm line in the element facing the desired forward direction,change directions by switching the 71 degree section. -------------------- So the forward element is actually feed at 155 degrees? </pre> Jim GM 2013-06-13T16:35:24 http://permalink.gmane.org/gmane.recreation.radio.topband/7605 <pre>All of my bare wire Beverages experience rain or snow static. Those with insulated wire -- whether BoG or above ground -- do not. Snowflakes and raindrops take on a charge in the clouds and discharge on contact with a conductor. Snow static seems to be consistently bad; rain varies. Gary K9AY From: "Bruce" &lt;k1fz&lt; at &gt;myfairpoint.net&gt; To: &lt;topband&lt; at &gt;contesting.com&gt; Subject: Topband: BOG antenna Noticed many storms have caused rain static on every ham antenna except my BOG. The BOG was very quiet and hearing stations in its normal manner.. I did hear a slight trace of something in there, one time when the noise was screaming on other antennas. Another local 160 meter DXer reported similar reception on his BOG. Wonder how many others have observed the same?

Gain variation with reasonable lengths of coax are miniscule and its not being wasted in a hybrid either.

OTOH its down quite a bit on the real low angle signals. Experimenting with a 2 wire and maybe some phasing.

Equal construction antennas require equal current. The current ratio controls null depth. Maximum effective front-to-rear and maximum gain always occurs at some phase shift more than 180 - spacing. So if spaced 45 degrees, maximum effective F/R (deepest usable null depth off the back) and maximum gain is some phase shift more than 180-45 = 135, or in the case of 1/4 wave spacing more than 180 - 90 = 90. Phase positions the nulls. I can't imagine anyone would want one single-point null at zero elevation off the back, when they could have a null cone that is just as deep and covers a very wide area, or why they might want less gain, since they get more gain with that null cone that gives much better F/R. Perhaps the problem is years and years of not wording things properly in our handbooks, or not thinking through the problem, has confused people. 73 Tom Al</pre> Tom W8JI 2013-06-13T13:17:46 Search the mailing list at Gmane query http://search.gmane.org/?group=$group=gmane.recreation.radio.topband
