Is what you are saying is that a 20 meter quad on a 8 foot boom is not as good as a 20 meter beam on a 8 foot boom???? C'mon Tom W7WHY -- FAQ on WWW: http://www.contesting.com/towertalkfaq.html Subm

I remember that article. I'd like to reread it. Does anyone have the reference for it handy? Dave Hachadorian, K6LL Yuma, AZ K6LL@juno.com ___________________________________________________________
To: <towertalk@contesting.com> Hi Tom, No, I'm only repeating what I read. When monoband large yagis were tested against equivalent monoband quads, the yagis did better. The measurements seemed to be

When there are tests which place the tested antennas on equal height towers, at the same general location, i.e., all things being equal, and then the tested ants are used in rcve and xmit to distant
Hi Charlie, I have had up and optimized many 2, 3 element and multiband quads (starting in 1958 through 1968) as well as 3 element Yagis etc. since 1956 so I have seen the differences. As for the sta
Hi, Just such a series of test, between continents, was published in some detail in Communications Quarterly, in about the Spring or Summer of 1992. I am pretty sure it was that year, since I put up

I agree that conventional wisdom is a powerful indicator of value/performance in products-- i.e., why are there no Yaesu MPs for sale used?? or no 40-2CDs used for sale, and why do guys still collect
I think a 4 el 20 meter quad on a 30 foot boom will beat a 20 meter yagi on a 30 foot boom. However, when the boom gets longer, the yagi will have more gain. I have used many of each and this was my
You missed the crucial meaning of the word "propagated" in the first answer. The quad can't tell the difference between, say, noise from African thunderstorms and the emanations from 9U5CW. However,
<snip> You are right, Ward, I missed the "propagated" word. The closed loop is quieter overall, however, it will receive "propagated" noise at the same level as a yagi with the same gain and at the s
By the way, by sometime this summer, I will have a 4 el triband quad on a 30 foot boom and a 4 el 20 yagi on a 36 foot boom, both at 75 feet. Maybe i can report back then as to the differences. Chuck
In addition, since the quad is, from one perspective, a vertically stacked array, its elevation angle of maximum radiation is equaivalent to a planar antenna at a point about 60% or so up from the b

L.B., What is that little * doing in your cute drawing signature of a beam and a mountain? Is * a little blob of RF eminating from your antenna? A photon of RF? Inquiring minds want to know. K4VUD --
To: <towertalk@contesting.com> Hi Chuck, Any noise that is not directly coupled to the antenna is "propagated noise". Unless your doorbell is mounted on your tower or installed on your antenna, the n
