All things being equal... IF you are using LMR-400 as the main feedline,
there is NO REASON to use a different diameter at the rotator...
The point was using a lower loss cable for the long run up the tower,
such as hardline, then flexible cable for the rotor/drip loop and short
distance to the antenna feedpoint. At VHF, this is typical.
Fail to see why an antenna failure or swap would require soldering "up
the tower"...
Failure is not necessarily the antenna. It could be the solid center
conductor fracture after being flexed too many times :)
If you swap antennas and it's a single run of cable, you have to
manipulate the antenna on the tower to access the feedpoint. Then, for
example, if you put up a longer boom yagi, the feedpoint will most
likely be further away from the tower and your existing feedline won't
reach.
