considered obstacles as UHF goes straight through buildings
unless they are made from steel reinforced concrete and trees
(although core conductive) don't attenuate microwaves that
much at all - unless its raining very heavily and the tree
has a full leafy spread,

A hill/mountain or large reinforced concrete building is more
of an obstacle. Effectively - can you 'site' the other party
easily - if so then microwaves of that freq will generally
get trhough,
