I've recently upgraded my node; it was at 35 feet, and is now at about 62 feet from my home in the northern Twin CIties, Minnesota suburbs.
The node is a Ubiquiti M2HP with a 9 DB omni antenna. Reception reports would be welcome, but I"m not going to hold my breath. 8-)

P.S. I also have a standard 900 mhz 802.11 Ubiquiti access point on a beam at about 57 feet. This is running 5 mhz bandwidth on 912 mhz; I hope the TV folks are not too upset with me. 8-)
