I am confused. The rotor and mast are a 25 pound wind load? That seems like a lot -- it is more than a big antenna. How can that be? I would have thought the mast and rotor would be minimal wind load
And to complicate it further take a look at the Sommer. <A HREF="www.sommerantennas.com"> www.sommerantennas.com</A> Sort of a combo log and yagi that covers WARC and can cover 40 and 30 also. I am r
I had one and also a Cushcraftt R7000. All verticals are subject to vertically polarized man made noise. There is nothing magic about the Titan to make it immune. Overall it was a decent atnenna on 4
OK - let's start a brawl. Yes, I have read the reviews on eHam and know the obvious stuff like the Mosley is a rotatable dipole on 12 and 17 where the C3SS claims gain. FTB better on Mosley. Size and

How to Understand the CCR Battle Hint: It is about frogs and camels, not antennas I am a real estate attorney and in my time, I drafted lots of CCRs. I can assure you no developer I represented looke

--part1_32.237a2562.29bdfb43_boundary Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit I just don't understand how a ground screen, unconnected to the antenna does anythin
<< 2) E-plane penetration of the ground and resultant lossy current immediately below. Solved with moderate DENSE ground screen. The worst loss is right underneath, so even radials shorter than 1/4 w
If you top feed the inverted L, you don't need/want radials. Check out Cebik's articles on the inverted L. <A HREF="http://www.cebik.com/gup25.html">http://www.cebik.com/gup25.html</A> and others at
I'd love to see them come up with a shorty version. Use linear loading or some other trick so you don't need 36 foot long elements! I would buy it in a heartbeat! Radio K4IA Craig "Buck" Fredericksbu
The WireMan sells this stuff. <A HREF="http://www.thewireman.com/wire.html"> http://www.thewireman.com/wire.html</A> Says it is popular for portable, weekender and backpacking antennas. That would ma
Be very very careful. If that thing gets away, you are dragging 300 feet of wire across the landscape -- including power lines. Even if it goes straight up at first, it will come down eventually and
I like your idea of the light duty link between the antenna and the balloon. That is better than a slip knot. But it is not redundant. In other words, if your wire and static line both came undone at
I use an old fashioned soldering iron. 75 watts. My small-tipped 250w gun got plenty hot but could not hold the heat long enough to do a decent job on PL259s. The big tip of the iron has enough therm
I don't know how the Trig would work but in the Boy Scouts we learned to measure the length of the shadow. Compare that to the length of a shadow from an object of known height and figure the ratio.
I have a tin roof on my house. I asked a lot of questions like yours and got darn few answers. I think no one really knows. It definitely isn't "ground" and you can't consider the roof a monolith bec
Can someone point me in the direction of a library of EZNEC sample files? I am just learning and it is a lot easier to tweak someone else's work than start from scratch. 73 K4IA Buck Fredericksburg,
There are two tables in the Handbook that will do the trick for you. One tells you the attenuation for a particular type of coax and the other tells you the additional loss due to SWR. They are in th
I'm gonna take a crack at this and I hope I can explain without getting laughed off the planet. There's a lot about +j and -j I still don't understand. I got mine yesterday. Comparing it to the MFJ c
