I'm in an exceptionally non-optimal area for PSDR, so I want to have as much information as I can about required mast height and link budget for each site before I go actually installing anything.<br>

>>> I've been able to find location info for most of the PSDR sites and antenna height info for some of them. Do they all have sectors pointing 0/120/240 degrees relative to north? 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.<br>
