Anyone recommend one for locating 500-1000m from a property and enabling
wireless access to PC?


The Davis VP2 range can do this provided you use a long-range repeater
unit and can achieve something approaching line-of-sight on the
straight-line signal paths. (Most wireless telemetry units these days
use very high frequency transmissions - strictly speaking UHF or ultra
high frequency (and higher) - and these links aren't really compatible
with intervening hills and the like. But splitting the link into two
or more legs can often help to work around such problems.)
