What distance are the buildings apart?
The Dishes have a very narrow ‘focus’. If the distance isn’t to far you could use the RBwAPG-60adkit.
Or you could have two links with four Dishes. They would not interfere at all.
The Wireless wire units (not dish) seem to be quite good at 200m or less.
I have not seen too much feedback discussing 200+ meters.
These particular units (non-dish) can be thought of as extended ethernet cable.
LIttle to no configuration just plug them in and aim and instant ethernet connection.
The wireless dishes the LHG60 ones, seem to be fairly stable and decent at least for 2000m and less.
Some folks using higher frequencies using CLI seem to reach beyond 4000m but I would say stick to 2000m or less to be conservative.
I believe they are configured the same. In other words no need to worry about config AP this or AP that. Simply think of them an a very long cable and you will
get the concept.
