bargain second hand big dishes for sale

[RimaNTSS]

There is 147cm antenna for sale not far from me. I personally not interested in getting it, but strange design this dish has. Looks like PFA, but, I think it is offset one.

Are you joking? That's the SMW OA-1400 again...

 

[RimaNTSS]

I know, just do not like those ties
There is ad itself http://www.2dehands.be/audio-video-...lliet-schotel/sattelietschotel-230556897.html
And, yes, offset angle 13*

Hmm, looks more like 120cm diameter dish... 8)

very good fiber glass quality .

Is that dish really made of plastic?! From specs I can not make this conclusion. If it is plastic and such a good antenna, I maybe contact chap who sells it and maybe visit him, just to take a look.
@skomedal thanks for providing links to specification list, seriously .

EMC Shielding + Acrylic top coat

Does that mean - plastic? Something like CM dish has?

...and how my SMW OA-1080 was made. Would be similar to the OA-1400 no doubt.

No idea what a CM is made of, but here's what Acrilic is -

Acrylic fibers are synthetic fibers made from a polymer (polyacrylonitrile) with an average molecular weight of ~100,000, about 1900 monomer units. To be called acrylic in the U.S, the polymer must contain at least 85% acrylonitrile monomer. Typical comonomers are vinyl acetate or methyl acrylate

Don't have a degree in Physics, so make of it what you will.

Thanks @Llew . Interesting dish. It has no mesh inside but reflective coating! Would also be interesting to see dish from its back, there is no strength ribs as far I understood. And 1,4m dish weights 16 kg, means that plastic is quiet thick. I am getting interested.... vill try to look at that dish,, maybe even tomorrow.
Can you post another page of that May 1993 magazine where is continuation of the article. .

Really fibreglass-reinforced PVC (SMC),
Yes, plastic again.
The SMC (Sheet Moulded Compound) material is very strong, yet easy to mold to the exact shape needed.
It also retains that shape.
See http://en.wikipedia.org/wiki/Sheet_moulding_compound

You can see the back of my OA-1050 here: https://www.satellites.co.uk/forums/threads/identification-of-old-1m-fibreglass-dish.161029/

Ahem... I thought it was no more dishes??

 

[RimaNTSS]

Yes, you are right..... I still hope that dish is in very bad shape and seller will ask too much and we will not find any logical compromise. But I wish just to see this dish, and maybe slightly touch it.

What I see clearly from picture of this SMW OA-1400 "Jumbo" dish as that, even though it is offset one but feedarms and LNB are shadowing signal - strange.

[skomedal]

Manufactures specs state " 5.5mm abs dish material "

And 1,4m dish weights 16 kg, means that plastic is quiet thick. I am getting interested

[RimaNTSS]

Yes, 16,2kg to be precise.
And, yes, 5,5mm x on big surface makes that weight.

 

[RimaNTSS]

I still hope that dish is in very bad shape and seller will ask too much and we will not find any logical compromise.

And one more obstacle- in my car I can fit maximum 1,2m dish Unless I borrow bigger car
