Thanks to all for the help.
Seems will not work right in my situation.
I have plan to rise a 190 ft tower having in mind the Comtek system of four
folded slopers, like K3LR use, maybe next year.
So this tall tower also will help to build the wire yagi, but I understood
from your suggestions that will be better the slopers system. At least to
have four directions.
Anyway how about a 3 element wire yagi and one of the slopers in the K3LR
system to the same direction in GAIN, wich one will have more gain?
About phased verticals I have a problem that is not good for me to put too
many radials in the farm, so I prefer something without radials.
Thanks again

Asunto: Re: Topband: 160 wire yagi
Hi Jorge,
some 20 years ago at YU1EXY, we spread sloping dipole and reflector (30m
apart) from 60m tall building to SW (at 45° angle), which created sloped
(semi vertical) yagi toward NW and which performed excellently. At
opposite side of building we had 3 el wire yagi for 80, made in same
fashion.
As far as I can recall, guys from Bologna (Italy) used 2 el inv V wire
yagi (switchalbe) at their "fungi" (water tower) shack, which also
preformed excellently.
IMHO, you need very tall supports for wire yagis, so IMHO it would be
better to build either wire 4-square or maybe sloping dipole array.
K3LR array would be excellent solution as well...
