Yeah,

my roof isn't that wide, I could probably only get a maximum spacing of a little more than 50ft between two masts...

How would I go about calculating the expected interfering signal strength between multiple antennas?

Is there an sflan18 or was I wrong... It seems that 18 was the only number missing from the map maybe all the nodes are already included?

A couple of recollections from my days in 2-way radio. (30 - 800 MHZ kind).

Vertical separation (on the same mast) gives much better isolation (antenna to antenna loss) than horizontal separation foot-for-foot.

A corner reflector antenna using a solid sheet of metal as the reflector probably gives the best front-to-back ratio and side-lobe response. The trade-off is higher wind loading than a grid reflector.
