What are the size, gain and cost considerations?

Should be able to find 5/8 over 5/8 over 1/4 wavelength to get 7.2 dBi

Sort of thing that should be relatively cheap/easy to fabricate locally. Perhaps 9-10 AWG

You can also drop data rates (increase SF) to get in the 14-27 KM ranges.

Precision of clocks also buys margin.
