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

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

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 sectors with

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. If
