Wireless Bridge CPE for a Link to another building

 I just installed a wireless bridge for a link to another building.  The distance was about 3/4 of a mile.  The results were excellent!  I had no knowledge of how to do this other than using repeaters to pick up internet from a house or two away.  This time I needed to reach a building that was a few blocks away.  

I used google maps to see if there was a straight shot between the locations.  Then I went up on the roofs but could not see all the way to the other end from either direction.  There was nothing visible in the way.  It was a narrow shot as some pine trees surrounded my house but there was a gap in just the right direction.  

I bought a model that has lots of LED's on the side to be able to troubleshoot any issues.  I installed the "A" unit on the roof of my house.  Then the "B" unit (You can change A to B with a switch) was installed on the building.  I was amazed at the results the signal level was 100%!  But there was no internet at the receiving end.  The issue turned out to be that I had two internet cables at my house with a union in the middle and lost a connection somewhere.  Switching to 100 foot exterior grade cables at both ends resolved that issue.

Here is the ad for the bridge on eBay:

This is the receiving unit.  I made a PVC rooftop mounting bracket to hold it on the peak of a roof.

This is the transmitting unit on the roof of my house.
