Make sure that you have data for the seasons as well, including wet and
snow. I have noticed a lot of difference on attenuation, reflection and
difraction with the seasons. We attributed such to the difference on the
trees, mainly conifers mainly firs.
Try a test if you can measure the known Tx and receved Rx.
