Asking the link owner to consider changing their antenna polarization is
a good idea although their antenna and labor costs to do that could be
kinda high depending on who they do (or don't) have on staff to do their
tower and antenna work and what antennas they are currently using.
With a signal that loud, even cross-polarizing to drop it down by 15 or
20 dBm would only lower it to -71 dBm or -76 dBm at best. It still could
be loud enough to significantly reduce the receiving radius of Mike's
possible new access point.
Often, when first installed, these links are set to run at full power
when they may not actually need to run that hot. Sometimes the link
owner will be willing to turn the power down a bit if asked. This would
help Mike to increase his access point receiving distance.
Depending on the direction that the signal is coming from, Mike can
sectorize, effectively "turning his back" on the noise. Then if he
chooses an antenna with the opposite polarization, he may be able to get
his small-area deployment to work OK.

NOTE to Mike: That will be 50 cents, please.

yeppers. something like that.
Triangulate in on where it's coming from and ask the folks that own the
structure the antenna is on.
It might be cheaper to pay them to change polarities than it is to reset
your plan.

Subject: [WISPA] What the heck chews up 100mhz of 5.8ghz?!?
While installing a new canopy accesspoint today, in an unserved
community with no other wireless isps and little else, I discovered that
I have about a -56 avarage across the entire swath of 5750mhz thru
5845mhz... what the hell?!?!? It's a small area deployment and we had
planned on a simple low gain omni, but not now... I don't know who or
what but 100mhz, is that really necessary? I'm going to take an sm later
and see if I can get a better picture and determine the direction of
these signals and see if there's going to be any way to make this work.
Out in the middle of nowhere. But does anyone have any idea what in gods
name could occupy this much continuous spectrum in 5.8?
