My business partner was trying to get me to go along with a 20 meter dish (at our HQ) to hit imarsat to serve oil rigs in Sakhalin island. I did not like any aspect of the deal, especially the fact the Russians would not give us any assurances that we retain ownership, that we have exclusivity or even simple permission to serve etc etc. Good thing too, they took over and privatized all the oil gear in that area about a year later. I am so glad I held back. Business partner only lost $25K on that venture. I lost nothing.

Or on a triplet set of redundant 3.5 meter size o3b terminals (active/active/standby spare) and the lower monthly cost of o3b service.

Brewster was such a great site for a quiet earth station that there is a huge radio telescope colocated just a couple of km away further down the valley. In the modern era with tight RPE Ku and Ka-band earth station dishes it's totally feasible to put a 4.5m Tx/Rx dish on the roof of a building in or near a major metro area (example: the recently built Ka-band sites located near Spokane, WA and Denver, CO) and make efficient use of spectrum without much worry about interference.

The HFT crowd has been coordinating 4 GHz between Chicago and New York and it will be interesting to see if any of this actually gets built. Engineering 6 GHz point-to-point can be just as difficult in many areas due to co-primary satellite uplinks that are licensed full-band, full arc.
