Don't put a Triax 110 with motor using the standard L type arm, you will lose it to the wind for sure 
Go for the T&K and pole option
Re: The neighbours, run them a feed and keep them sweet, Lol
Sorry had to,
I wouldn't put a 110cm on a DiSEqC motor esp.. on T&K high up, others may have different views. 1 Mtr yes !
The STAB motor is good, no noise but very slow unlike the Moteck
