Hello,
Thanks for posting this, refreshing to see a little-known dish pictured.
Never knew there were dishes made in Canada!
Not sure about the mesh size inside, or accuracy of this, but you must be prepared that this could turn out to be a C-band dish, rather than a general-purpose large dish.
Can you share a little about what you would be trying to receive with this behemoth?
Are you thinking modern Ku-stuff, or C-band?
Also, are you thinking of using this for a single position, or are you contemplating using the polar mount?
If the latter, I would probably suggest you put some energy into refurbing the polar mount (bushings, bolts), as it looks to be a bit weathered...
Do also consider where you are going to mount this. It will require some concrete or good wall-mounting brackets to make it (not) fly!
Looking forward to your thoughts on this.
(and eventually the install!)
