New toy: 2.4m Prodelin offset dish

Hey-ho, time for the bigger stuff...

Just acquired a 2.4m Prodelin (General Dynamics) 1241 dish in reasonable condition at a very reasonable price-point. Dish is a four-petal SMC thing, with 6.6" pipe-mast interface. (!) Weight is fairly hefty, the weight-ratio between dish and mount has now flipped, the mount weighs FAR more than the dish.

Dish is from 2014, and was used as data-link device for geological surveying (mining prospecting) on Greenland during the summer. (Very exotic indeed, compared to sitting in somebody's backyard for a couple of years.) Very little wear, only a few minor scratches and a single tear in one of the petal back rib structure. Shoud have no impact on performance, given the construction. No rust anywhere on mount.

Unfortuantely the dish didn't come with feed-arms or LNB supports of any kind, so I am looking to see what spare parts would cost. However, the dimensions are fairly well documented, so it should be possible to whip something up on a shoe-string.

What the dish DID come with was a Baird non-penetrating roof mount for large dishes. Weight approaching (without slabs) a quarter of a tonne, and sturdy as hell! Makes all the stuff I've been dealing with in the 120-180 cm range looking quite flimsy. Well worth the purchase, as these are about $2500 from new (in the US).

To be honest, I'm not entirely sure what to do with it. Of course it is tempting to erect and measure 28.2E reception in my garden, but the dish and mount has extremely low WAF (although VERY high HAF!), and the local council will most likely descend on me like wasps when somebody sees the thing looking skywards.

Also, there is the fact that very few satellites that I can see in the Clarke belt warrant this size dish to receive. (Unless motorized, and I don't even want to start thinking about the cost of the polar mount for this thing!)

Soooo - it's gone into storage for now...
Let's see what springtime brings.

Seller did provide one picture of the installed dish on Greenland. Note the upside-down mounting of the feed-assembly mandated by the very low elevation of the satellite.

My yard is deigned for it, so when you decide to get rid of it, just say that :rolleyes:

Hmm, very nice, a dish like that might even get me Astra 2F Europe beam 24 hours a day in Helsinki in bad weather.

So if you have extremely low WAF and a problem with the council with not much need for extra signals anyway, why did you buy it? Or is all that irrelevant because of very high HAF? ;)

Very nice :cool: It's only HAF factor that matters to me. :D

Just....wow!
I had a hard time believing this myself, but it turned out to be the real thing. Dish + mount, all of it less than a year old.
Apparently it was purchased as a solution provided by a North American company, with uplink services and everything included. When the site closed down, the solution provider just took the electronics, but couldn't be bothered to haul the antenna hardware back from the middle of no-where. Luckily the prospecting company clears out everything from their sites, and the dish ended up here in Denmark. They were freeing up some space in their warehouse, and put this in in the local version of Loot, and I happened to see it just hours after it came on. Amazing...

Isn't it ironic, that I recently in your sat playground thread said
I see.
You really seem to find the exotic stuff! Nothing remotely like that here in DK... 8)
...or maybe that's fate intervening?

A little less analogue, and a lot more crap.

Very nice, the geometry is the same as the 1244 series at 0.8 f/d, and there are plenty of those about, so getting a feed assembly should not be difficult at all.

If you are prepared to wait the five - six weeks then you could get direct from the manufacturer.

What type of motor/polarmount are you going to fit ?

Lucky git!


Some people have made temporary feed arms out of wood or put a wooden pole in the ground to hold the LNB in position while new feed arms were fabricated or were on order.
