Installing a wireless point to point ethernet bridge

UPDATE: 5/29/14: While these antennas worked perfectly fine, and I was getting an excellent ping VoIP was still an issue with these antennas, so I had to take them down and run a wire from one of our customers in the next building over. If you are doing anything other than VoIP these antennas should be perfectly fine for your use.

I am currently in the process of installing a wireless point to point ethernet bridge between two buildings. 

Mounted 1-1/4" PVC pipe as an antenna mast
and installed antenna on chimney.

The original plan was to run CAT 5 between the locations, but the distance was nearing 400 feet or more - which is well beyond the recommended 300 foot length for CAT 5 cabling.

Antenna mounted

Both antennas have been mounted and aimed at eachother. Outdoor CAT5 has been run from the antennas to the inside of each building.

The antennas have been set up with unique static IPs which are on a different subnet than the WAN that they will be bringing between buildings.

distant building is the one with the elevator enclosure on the roof.

The main antenna will be connected to a T1, and the remote antenna will connect to a router to provide internet for the far building.

This is where I brought the CAT 5 inside from the roof.
It connects to the PoE injector, then connects to a jack that goes back to the patch pannel.

Cable internet is currently at the location where the T1 will be extended to, however it has been causing issues with the VoIP services. FiOS is not currently available at the location, and Verizon provided a ridiculous construction cost to bring a T1 to this location. (Think the cost of a brand new mid-range vehicle)

This may not be the ultimate solution to resolve the customer's issues, but it should at least provide the ability to separate their voice and data internet traffic.

Currently I have spent about 5 hours on site running wire and installing the hardware. I have already tested the antenna in the lab.

I have about 2 hours left to connect the antenna to the T1 and complete the configuration of the network(s).
