I wonder why you chose the 150cm dish?
If 120cm would do the job, I would suggest you look at
this one, based on the construction of the mount.
We've had some members find it difficult doing elevation adjustments on 100 or 120 Fortec dishes.
They seem to lack a pivot pin or bolt, and have no fine-adjust screw.
From the pictures, yours looks about the same.
I like the STAB brand motors, and their 120 is the big one.
This vendor is a
little cheaper.
...and one of our site sponsors.
Did you have some special concerns , such as local delivery, or customs, shipping, or other interest in your vendor?
What receiver , LNB, and other accessories were you planning on using?
Where were you going to install, and which birds were you shooting for?
Reason I ask, is because we have had some people outside North America come here seeking help, and without knowing their special circumstances, it's hard to give good advice.
