Dr.Dish:
H to H is fine, if the dish is not too large, because all the power of wight
and wind is concentrated on one point. Therte is large H to H mount from
Jager. A friend is using this mount for a year or so on a 180cm dish without
any problems.
Magnetic polarusers could live a little bit longer because no mechanical
parts are involved. A servo is better in attent. of the opposite
polarisation. If you will use c- and kuband, you should use the
servo-version. Beware of no name products or cheap copies
