If you stack 4 of those elements, and it is omnidirectional, then the gain
has to come from somewhere. Where does it come from? It would probably
compress the take off angle, but in terms of beamwidth gain relative to a
Yagi, it couldn't have any.
It wouldn't allow you to null out noise coming from a specific direction,
which can be useful also.

This is a response to several posts. First off Yagis. There are some
newer
people that seem to lean towards loops.
Why? What is the attraction of a loop over a yagi? Simple common sense
should tell one that a larger antenna will perform better.
. On two occasions I tried to give one
of these guys a real 6M antenna. He turned me down, >because he knew
his
160M loop was a much better antenna.
Yeah, we have on of those types here as well. He instructed me one
morning at the club breakfast as to how a G5RV will outperform a SteppIR
yagi. You just give up with those types.

The thing I have always been curious about is why folks *don't* stack four
loops on 2-meters to get decent gain *and* an omni pattern. Total gain
will be about 7-7.5dbd and can be nicely fed by a 4-port power divider.
This would, of course, be for fixed operation only because of the physical
size. This would compare with a modest yagi and you don't have the hassle
of constantly rotating the antenna for fear of missing something.
If you get *really* ambitious you could stack 8 loops for 9+dbd gain. :>)
I know that ND2X used to run four stacked 432MHz KB6KQ loops in his mobile
system.
