On a 10 MHz channel, getting 8X/6X, you should be getting in the
neighborhood of 40 Mbps. More if you can eek out 8X/8X.

can you set up some 900 test shots?

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 ;-)

The length of the needles matter.

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