SNIP For a tower of 60 ft or more, it is trivial to add a trap dipole or small (2L) tribander at 30 to 40 ft to fill in the unavoidable 10 to 50 dB NULLS in the vertical plane pattern of a higher Yag
While it is nice to have an antenna that compliments the nulls of another antenna with a nice lobe, there are other worries. All my life I have used high yagi's, and never have noticed a problem. Wh
I would appreciate hearing from anyone who has added a small yagi to the top of one of the mid sections of a crankup--say at the ~35-40' level. In particular to the interim TRIEX LM470 (built by Para
You raise some good points for large station design Tom, but the original topic was filling in the NULLS for a SINGLE (moderately) high antenna, presumably a tribander. I'm merely suggesting that for
I, for one, do not doubt that lower antennas are at times better than high ones. I have done experiments with my crankup tower that have convinced me. But that doesn't seem like the relevant point un
I heartily concur with Mike. Being a "one antenna guy", my Mosley Pro57B is at 40 feet, as high as I can reasonably place it given my extreme weather conditions (125 mph gusts and very heavy icing).

Guys, this has definitely been one of the more interesting threads on towertalk I can remember! For me more an intellectual exercise than reality!! .....I mean, I've been chuckling all this time....b

Leave us not forget that one of the reasons for putting up a high support to start with is to also have a place to hang wires as high as possible. My C3XL is at 82'. I wouldn't want it any lower beca
Similarly, I have the C31XR tribander at 72 ft and Kevlar guys. I've been tempted to add a C-3 at 35 ft or so, but so far don't think it would be worth it for my operating habits (soft-core contesti
One benefit of 'Higher is Better' that I haven't seen mentioned does pertain to urban location guys like me. Higher means farther away from noise sources like power lines. Higher means farther away f
N4KG: Higher means you can hear more noise sources farther away. N4KG: Higher means you can interfere with more neighbors farther away. N4KG: OK, I'll give you that one. _____________________________
it Do you bust through all the pileups to EU / AFR on 10 / 15M? If so, then maybe you don't need something lower. You'll never know if you don't compare. Try a dipole for starters. I can follow my 1K
OK, I've got to throw in my $0.02, since I spent months playing with TA trying to optimize antennas at my QTH. 1. There is more up to date propagation than the antenna book - I think it's on the ARRL

That's good advice. While all the talk about patterns over perfect flat earth with no buildings is useful in that environment, we all don't live in the country on cattle farms or on golf courses. If
Tom, you have not answered the question. You changed the question. The question was NOT what a one tower guy should do. It was "what should a one antenna guy do". I don't know all the reasons why a g

N4KG responses inserted below. Guilty as charged. I simply would not limit myself to only ONE antenna. It's pretty easy to sidemount a small 2L Yagi or dipole, even on a crank up. ANY high band anten
