Give me a shout when you are ready to sell it at the right price I would be interested.

Ok will give you the first refusal on it when mount is finished

blademedia,

I look forward to your installation topic, it will be a very good read for the "Prime Focus Men", best of luck and I hope it goes well.

Install will be quick fist time round, the performance might shock a few people, ive had them for years, don't get me wrong channel master is a good dish but not quite in the same league as a spun dish

I have something similar, but did not try it yet

I still have mine from long ago when it was used on a 3.1m Winegard mesh. It worked well on C band with a "golden ring" (a ring inserted into the end of the WG to illuminate deep dishes correctly). Ku performance was only a bit better than the 1.5m IRTE but that may have been more to do with the f/d of the dish and its mesh construction. I also found that the SMW ku LNB I used at the time has very poor phase noise. I'd like to try the Co-rotor again but it need a new servo.

Would love the 2.4m CM but I am just on right side of "sane" with my neighbours with the 1.8m.

Ive got some spare Chaparral servo's G, do you want one sending down ?.

I loved my 2.2 Precision PF as well ... fabulous dish.
Found it to be more precise for lnb focusing over the CM1.8 but sadly never had the chance to use more modern electronics on it before it got storm damaged.
The CM 1.8 offers more lnb experimental possibilities for me, which is what i like to do, there's Ka, Ku, C & Extended C on the changer at the moment but if i ever had the need to go for a single band only at focus position i'd go for my 2.2 PF as well.
Crack on with it then, look forward to install progress pics ;)

Its just lots of messing around bodging/fabricating things for O/S dish lnb, more ready made all in one solutions for P/F dishes,

I have a 1.8 channel master that I might install at some point and fit 200lb of lnbs on it

anyhow not getting into a debate

if it works for you its all good

Going to crack on John when rain stops

From memory Precision dishes when made in Stratford were graded based on the amount of care that had been taken with the broom handles. Whilst IRTE were pretty well consistent in the gain and frequency response, there were differences between the TVRO and receive/transmit grades despite the reflector coming off the same production line.

The 1.8m I have had on the roof for a number of years is virtually identical to the response from the 1.5m at Ku band despite stringing to check. I may replace it with the 2.2m reflector I have in the garden when the weather improves.

Stratford, one of my fondest memories was hiring a pick-up van and trundling off from here in North Notts to Precisions factory to pick up my 2.2 plus "A" frame all crated up on a pallet. Had the pleasure of having a quick peek into the factory bit that was next to the yard where they stored loaded pallets.
Think you could be spot-on with the grading thing CH, mine was ordered as a TVRO piece and i can distinctly remember seeing on the back side of the reflector circular marks at every 6mm or so spacing as if that was the pressure point of the broom handle & roller whilst being spun ??.

blademedia,

Those spun aluminium prime focus antennas are a thing of beauty.

Did you ask the eBay seller where he got the dish from? I think there used to be a few USA air force bases in the area where you collected the dish from. Considering it is a USA manufactured dish it might have had military origins? Whatever the origin, I am sure it will be a top quality dish when you get it into service.

Yes he bought it direct from DH satellite, the seller is a satellite boffin, it was bought specifically for adverting his business and to use for testing things he made, the feed could well be made by him, he's made parts for the bbc etc, A very clever man with fabrication skills to wipe the floor with is all,

He is going to email me some of his work with his consent I will document it

Nice dish, novel approach to stringing it.....

Thanks

That's one thing that's been on my mind, not expecting the dish to be straight, I will put a few strings across it once its up and see how much its out,

I will make some spokes like they use on the bigger dishes if so when I'm restoring it and pull it back into shape
