It's not as trivial as you might think. Getting those things to couple
just right is almost an art. If you've ever taken one of those things
apart, you'll know what I'm talking about. Most of the ones I've seen
appear to have the dielectric between the striplines hand cut and the
thicknesses
I'd be cautious about those Pancake shaped OMNI patterns at 16 DB.

This one is 15dBi minimum from MTI...

I'd expect to pay somewhere around $550 or so for it though
Other than that I have only seen 10 and 12dBi ones typically.

I have some slightly used 15dB omni's if you need any.

I also have a box load of maxrad 9dB omni antennas if anyone needs them.

Tom,
This would not be serving any customers, all the locations will be at
least 100ft+.

You won't find a 5 GHz omni at that gain, and if you do, I'd call BS.
The vertical beamwidth on an 16dB omni antenna at almost any frequency
will be so flat that the antenna would be practically useless. We make a
9-10dB 5.7-5.8 H-pol omni for ourselves, but very few as we just don't
use that
What about sectorized omni arrays, any of those out there at 5.8?
An example would be

Just can't find anybody who sells it to get an idea on pricing.

I would be very concerned about
That is not really an omni. It is three sectors meant to be fed with
three different radios. That being said, and in regard to my last post,
a back to back array with a couple of 90's fed correctly would yield a
pretty nice omni pattern that you could get close to 16 dB. Two 18 dB

Your prowess as an antenna designer is well known. Define a decent
splitter, and where one might find one. I think that solution would
be usable to a wide group on this list.

I nosed around the Internet looking at the various designs of
stripline dividers. It is almost trivial to make one. But the more
I think about it, if I am going to coordinate a climb to hang a pair
of antennae, I'd probably just carry two radios up and run them
separate and sectorized.
