Is that alot?
8 degrees would be a lot, given limits of lunar lander antennae adjustment.
A fellow mentioned 8 degrees, but that might actually be in regard to a tilt during descent - immediately before landing.
Perhaps, upon landing, a better orientation - would be nice.
But overall, the lunar lander antennae apparently have a limit of physical adjustment.
The antennae are directional. Need to aimed at earth.
Big antenna in Australia, might compensate or be in a better location to receive/transmit.
