Help With Dish Identification

[Gray1]

Got another dish yesterday from a Quicktrip. It was a dumpster save. It measures 38 3/4 and is round. Anyone wanna guess what it is? I think its a .98 Prodelin but not sure. The mount measures 2 1/2 which is bad since all I got here are all 2 3/8. Think I could make it work? Got 8 lock down bolts for the post. Anybody got any experience with these dishes for FTA? Any help would be appreciated.

Thanks

Congratulations, looks good!

Not sure what brand it is but it's a goodun, nice find.

You can definitely use a 2 1/2" mount on a 2 3/8" pipe, just shim it with a little aluminum flashing wrapped around the pipe.

Especially if it's going to be a fixed dish, it really doesn't matter if it's on a plumb pole/mount anyway...just aim it, skew it and lock it down.

judging by the thick lower feedhorn support bar with the slight bend in it I'd say Prodelin also Nice find!

Those 8 mounting screws are setup so that you can level the mount - perfect for mounting on your 2 3/8" mast!

Give her a wash, aim, and enjoy. Nice dish.

Any Idea how to get those God awful decals off from it?

 

[migold]

Can of grey primer spray paint...

Quite often the adhesive is dry and light sanding removes the decal before painting or the decal will show through.

Brake clean spray if it's an adhesive back decal. Get a corner up, spray, pull, spray and repeat.

Thanks for the advice. You all think I should try to straighten that center LNB Bracket? It originally had a transmitter on it or should fabricate a bracket to hold LNB?

Thanks

I would use the original arm and if available the original matching feedhorn/scalar. Do you have the original feedhorn/scalar? If so, it will likely provide the best performance matched up with a polarity switching LNB or two LNBs with a 13/18Vdc switch.

If you don't have the original feedhorn, one of the members may have the original feedhorn and be able to provide the height to the center of the feedhorn and the distance from the reflector. Using these measurements you could easily fabricate an appropriate height riser LNBF clamp with fore aft adjustment.

Gray1 I think you have got 1m Echostar (same as Prodelin) PFA dish. I have the same but with easier strength ribs, anyway you can see very similar mold. Let's check: Distance between mounting holes is 315mm!

 

[FaT Air]

No original feed? You could calculate, with some measurements, with parabola calculator 2.0.
Maybe do a check with polygyver's mirror method

Titanium...I don't have the original feedhorn. The installer said he had to take that back with him. I did see it. It was tall. with a large feedhorn. Had fins like a transmitter.

RimaNTSS.... Mine also is 315 mm between the 4 mounting holes to the bracket. This dish is only 38 3/4 round.. I believe a 1 meter would measure 39" wouldn't it?

 

[Gray1]

Pretty sure this is what I got.

I measured mine dish, it has 978 x 978mm working area and 65,1mm depth in the deepest point. Deepest point is located at the very center of the dish, therefore it is Prime-focus dish. It has F/D ratio 0,94. This is mine. Measure yours and find out dish characteristics.

Gray1, thanks for putting up that web site. I was able to find a dish that I got earlier this year. It turns out to be the 1134 series dish. It even included mount and all. Now I have all the specs and data for my dish and mount.

 

[Gray1]

RimaNTSS... Mine is a little different. My dish is also deepest in the center. I measure 987mm OD and 78mm deep. F/d ratio should be .79. Double check me but I think that's right.

bigg t....your welcome. Glad it helped you
