What if: BBC World Service Relay Station in the Falkland Islands (c. 1977)
....

For simplicity, I will say that it will have the following capabilities:
2 x 100 kw SW transmitters
3 x 500 kw rated HR 4/4/1 directional antennas aimed at Western South
America & Pacific Islands (NZ & Australia)
-- HR 4/4/1 is a very standard antenna type, with 23dbi gain

I will assume that the site is placed next to the sea near cliffs, but some
50 km from Port Stanley.
I will assume that it is desil powered, but would only run 12 hours / day
[high-power] to save on costs.
I will assume that Patagonia would get about 18 hours / day of BBC WS
service

Conjectu
The Falkland's War would not have happened due to this showing of super
power strength, among dozens of other military related issues assumed to be
constant...
