I don’t know the formulas to calculate the passive back to back dish size needed, but formulas or calculating programs do exist.   Marti was able to calculate the passive back to back dish sizes needed to make the 950 STL work.   He said we would need three four foot dishes and one 6 foot dish in the system.   The hops were about 1.5 miles, and 1800 feet.

Maybe practical if the hops are short enough.    Such a system was feasible for a 950 Mhz STL link for a station I used to work at.   Two back to back passive dishes mounted on a hilltop that was in the way.   No AC power needed.   Marti calculated this to be do-able.

Just thinking outside the box, here... what about a 100% PASSIVE relay system? :)

I assume that the site with the clear view of the ISP is such that you could easily mount a good dish pointing at the provider, and another good dish pointed at your site? Between the two, nothing more than a short piece of coax or waveguide. No power needed! :)

If the dishes have good enough gain, then it should be enough to allow a dish at your site to establish the link with theirs.

I know some of you have faced similar issues getting Internet and/or STL to geographically challenged transmitter sites. And, many of you know how to work with limited budgets. I look forward to hearing about your innovative solutions to this problem.

Thank you, my friends,

Michael
