[HamWAN PSDR] Site details?

[Stephen Kangas]

Nick, I'm not certain why precision matters here.  My experience working with Bart & Doug assisting them putting up the Rattlesnake Mtn sector is that they may deviate from the exact bearing only to provide better coverage to the area below, avoiding obstacles and focusing on the user community.  We're not talking really narrow beams here.  You should be able to expect that if there is a sector antenna pointed to your area that it is optimized for your chances of connection regardless of how precise the sector antennas matches 0deg N bearing offsets.

FWIW, Stephen W9SK

Those are the standard. I think there is one single sector site where that varies, but am not certain.

Sorry, I phrased that part poorly.  Are all sectors aligned at 0/120/240 when present, or do they deviate from those bearings?

Is there anywhere that has EIRP info?  I'm trying to see how tall a mast I need to get connected, and whether or not I can even make link for some of the sites.  For example it looks like I "only" need a 35' mast for Baldi, but at 28mi away I'm not sure I can get connected reliably, vs Beacon or Capitol Park which are much closer but I'd need at least a 66' mast thanks to local terrain and trees.
