Wasn't Goonhilly built because the Telstar signal was so feeble it needed
to be as far west as possible?

"The site, approximately 800 yards square, was chosen as being
particularly suitable for the transatlantic path in view of its westerly
location; also its latitude is convenient for satellites in equatorial
orbit. It is remote from the majority of microwave links in the United
Kingdom, so that frequency-sharing with such links is facilitated. The
horizon angles are predominantly negative with a maximum positive value
of about 0.5°, so that satellite orbits involving low angles of
elevation could be used." - Bray, W.J., "Satellite Communication
Systems", POEEJ, Vol. 55 Part 2, July 1962, pp 97-104.
