My latest project:
I acquired this dish in spring 2016, specifically to use it for C-band as a "micro-bud".
1.2 meter offset dishes are nice, but while being only marginally larger visually, a 1.4 PF dish is 36% larger area-wise than a 120cm - could make a real difference with C-band.
Seller said it was mounted on a house he had just bought, and he just wanted to get rid of it.
Feed-arms are visibly bent, looks like handling damage. Should be ok with a little twisting.
There is evidence of some slight bending and scuffs on the edge of the dish here and there.
But the surface seems generally ok too.
I strung the dish to check for any warping, and it seems to be in very good shape.
The dish came with a nice sturdy wall mount, which I wanted for other projects to begin with.
The polar mount, unusually, included it's own, welded-on bit of 60mm pipe.
This fits right into the wall mount, but is not directly compatible with anyhting else I have.
Two apparent challenges with the dish:
1) Feed-holder was originally for small bore feedhorn, now somewhat crudely butchered to accept 40mm LNB.
2) Polar mount with the 60mm tube is not easily mountable on normal mounts.
Unfortunately, the original feed-horn was not supplied with the dish.
Instead it came with old universal Ku-band LNB strapped on with a cable tie.
I am curious to see how much signal is lost from the f/D mistmatch if I compare a universal with a PF LNB...
The polar mount is steel-plate rivetted job, and has nylon/plastic bushings.
Metalwork is galvanised then powder coated.
Channel Hopper thinks it's a Lenson Heath mount - perhaps the dish is a Lenson Heath thing too?
There was no actuator - only a metal rod for manual installation.
The plan now is to set-up and align dish with Ku in a test configuration, to get my bearings.
Then I will swap the feed for a C-band one and see what I can find.
Later options include permanent mounting on wall, and multi-feed options.
