If I do this, I’ll probably use 5Ghz for the

I should add that in a typical environment
with wood frame houses/other structures, it
helps a lot to choose the 2.4 GHz channel on
the home WiFi AP for each CPE location, so
that none of them overlap with your carefully
predetermined 10 MHz channel.

2.4 in 10 MHz channels goes through a decent
amount of trees within 1-2 miles max, if all
the CPEs are nanobridge m5-25 dishes or
similar sized reflectors...
I've seen such setups with clients in trees
and signals right around -69 on both chains.
Not a lot of aggregate capacity per sector
however.

I've never had any luck with 2.4 going
through much more than the side of an aspen tree.
can you set up some 900 test shots?

So given this scenario, would 2.4GHz be
better? I can use 5GHz inside the houses.

I have not measured one, but if someone has a
pine tree nearby and an ohm meter, measure
the resistance of the needle. Make sure you
jam the probe into the interior of the thing.
I am guessing that the water content of the
needle absorbs some of the RF energy al la a
microwave oven. But anecdotal evidence over
the past 10-15 years has shown that pine
trees are worse than others so if the needle
itself has a fairly low resistance, like 100
ohms, it is acting like a dipole with a
termination resistor. That is really going to
suck up the signal.
Stealth aircraft have microwave absorbing
foam on some of their surfaces that operate
by similar principles.

the wavelength of 900Mhz is ~33.3cm so a
quarter wave length is ~8.33cm (~3 1/4 inch).
Ponderosa pine needles (and many other pine
needles) are around the same 3 1/4 inch
length
https://en.wikipedia.org/wiki/Pinus_ponderosa
so with water in the needles you have a big
900Mhz RF scattering/reflector ;-)

Ponderosa? Fir? Cedar?
The length of the needles matter.

Realistically, what kind of distances do you
get through these types of trees?
