. net... Yes, he spent a few bucks on this project! http://www.1982crew.com/PHP-Nuke/PDF/K9LTN.pdf my question is Why ? I mean he has the ability to do it obviously, and the technical to do it yes. But Why. Is it that much more over a standard 4 elem steppir at say 70 FT. It wont open propagation that isn't there ? Just seems a waste to me Scotty W7PSK |

You have raised an interesting question - When do you reach the point of
diminishing returns? "R. Scott" wrote in message ... "John, N9JG" wrote in message . net...

Just seems a waste to me Scotty W7PSK "Waste" like difference between magnifying glass and a microscope. You would not say that if you had a chance to be behind one of those. Antennas like that make their own propagation, when rest of the 3 - 4 el. slobs can't hear a thing, the real antennas like that can still do so for another hour or two, or just do it anytime. I had "just" couple of my stacked Razors and that extended my propagation over mortal Yagi variety by hour or two. I figured I had about 14 - 16 dBd on 15m from stacked 7 el. log Razors http://www.k3bu.us/razor_beams.htm If K9LTN had 6 Razors that would be a notch higher killer antenna. |

Well, if i am not mistaken, in order to gain another 3 db, he would
have to setup another similar array. That would be twelve stepirs. Then for another 3 db, he would have to add yet another twelve stepirs. The second three steppirs only gained him 3 db over the first three and the second steppir only gained him 3 db over the first one. so, what does that three db mean?

Buck, N4PGW Yeah, I especially question the practicality of going from 4 antennas to 6. It picked him up less than 2 db, but doubled the physical size of the array - same width, twice as high.

Three Db equals a doubling of power or halving of power depending on which way you are going. Dave WD9BDZ |

Dave WD9BDZ If I looked at his numbers right, his vertical stacking is way too close (1/2 wave), and he won't get 3 DB. OTOH, he got himself a super 6 m antenna. Possibly enough for moonbounce.
