Reflection loss can vary from zero to infinity; depending on the
material
and angle of incidence.
====================================

Yes I know. That's obvious.

But what I would like to know is a typical or average value, or a
range of most likely expected values found in practice. Some
experienced person must know!

Needed to crudely ESTIMATE ionospheric multi-hop path loss.

Ground reflection losses are a small proportion of the total path loss
but not small enough to be neglected.

Just a whole number of decibels per reflection will do please.

Some approximate examples at 7 MHz with angles of incidence
from 0 - 40 degrees:

Sea Water 0.2 dB
Rocky Ground 5 dB
Average Gnd. 2 dB
