360degree access via Sector antennas
Place three 120deg antenna's on a tower, on channel 1,6 and 12. Connect three meshboxes via their EtherNet port to a SwiTch. The switch connects to a RouTer. The RouTer connects to the Internet uplink. Each sector antenna pivots around it's axis for the best possible connection.

Do not use 15dbi Omni's for 360degree access, it pollutes the spectrum and wrecks the Wi-Fi experiance for everybody.

Repeater nodes
If two PCI cards are installed in one PC, insert a double sided PC bord (copper) between the cards to prevent RF interference. See FaradayCage

Ideally the two parabolic antennas back-to-back should be seperated by 6m so as to prevent RF cross channel interference. There must be six channel seperation between two back-to-back parabolics.
