What I am trying to do is get 180-200 deg of coverage with H-pol. The
location is at a lake shore and I do not wish to waste power by
radiating toward the water.
I have a similar setup using V-pol 120 deg sectors at another location
that works just fine.

Of course you're going to have nulls! All over the place too, not just the center. That's a whacky setup you've got there... What are you trying to accomplish?

I currently have 2 16db H-pol sectors each with 100 deg beamwidth.
I have a splitter and have carefully made the cables from the splitter
to the sectors exactly the same length.
I placed the sectors at the exact same height and at an angle centerline
to centerline of 100 deg with a separation of about 5inch.
It seems to work, but I have some odd gaps in the coverage. There seems
to be a null about 10-15 deg wide in the middle of the 200 deg span....
Also, the outer ends of the span have quite low gain.
any ideas? Anyone done this before?
