A bright light source on one building, and a mirror on the other. There are also toners that microwave radio installers use. Basically low cost transmitter and receiver that gives a tone for received signal strength.
I want to make a connection between two buildings some 1.5 km apart in a city.
There is no free line of sight.
But maybe with two poles of 5 meter on each rooftop high it might work.
But you can't climb in a pole - and spending time creating the whole network just to find out it has no connection is a waste.
Is there a simple (electonic) test / trick to test if the top of the two poles can 'see' eachother?
Thanks for any help.

You need more than just line of sight -- you need a clear fresnel zone. Check Wikipedia.
