a lot of blind luck (get it wrong and you create
multipath inside the cables).
This'll be a tough one.

It's probably ducting. Where the conditions in the AIR literally bend the
signal over or under your receive antennas.
You'll likely have to put in a system designed with something called
antenna diversity. Basically two antennas for each

I will have to second the ducting analysis. 23 miles is a long way
over a water path. You can use space diversity by using a pair of
antennas/radios at the same frequency, with 20 foot or more of
vertical separation. You could try frequency diversity also. Many
times a duct will affect

Its relevent to disclose the radio OS type using. (You stated using a R5H a
Mikrotik card, but weren't clear if using Mikrotik OS).
The symptom you are explaining sounds similar to how some of my Mikrotik OS
units had responsed to noise.
