I was involved many years back with a commercial installation of 2Mb/s
microwave equipment (used a dish antenna) and laser equipment.
Both worked; both were line of sight.
The laser stuff was more fiddly to set up and suffered from loss of signal
as the buildings moved (thermal expansion) so we eventually gave up on it.
The microwave gear was good, but sometimes failed on misty days as it was
absorbed by the water droplets. Strangely enough it was OK on rainy days,
although the signal was definitely down.
Be very careful with local government regulations though; people are known
to get hysterical over anything that looks like an antenna (even if it's
receive only!).
By the way you may be interested to know that microwave radiation can be
ducted by tropospheric effects so that your signals can at times travel a
lot further than you expect.
I think the present Australian long distance record for one of the ham
microwave bands is about 380 km, and they used dishes and I think about 10W.
Regards,
Jill.
