120cm fibre dish, anyone knows this brand?

**kamaleon** · 28-01-2009

Hi folks I've found someone that's selling this dish not far away from me, anyone knows what make is it? it says SEMAC but I've never heard of it. TIA!

Could be ex Turkish naval encrypted coms gear... looks very well made.... check the frequency on the lnb etc..

**kamaleon** · 28-01-2009

Coincidentally, scrolling down this forum section I found a link to this Ebay

seller, he seems to be selling a dish slightly similar:

otherwise, the lnb on the unknown brand fibre dish is a pretty old one, and the fitting for it seems to have been DIYed. What should I check for? Why?

pedro2000uk · 28-01-2009

if it's been modified it won't be the original - the original would have given clues to it's use but also to the spec it's been made for... f/d ratio focal length etc.. and possibly the optimum frequency of the reflector material in the fibreglass.

**kamaleon** · 28-01-2009

rightey, I (sorta) get it. You mean the actual lnb should specify the reflector material frequency? didn't realise that. I'm not particularly interested in this dish, but the seller also has a nice fibostöp and he only wants to sell the two of them unfortunatly

pedro2000uk · 28-01-2009

the size of the dish & the fact he's used it for dth probably means it's OK* ... the build quality looks very good indeed - depends on the price too...

*ask him what sort of results he got on given known weak sats etc..

**kamaleon** · 28-01-2009

He's not very friendly, unfortunatly I can't ask him anything else. I'd be keen on getting the fibostop but I have to get this one as well, problem is I have nowhere to put it, and I don't know how to sell it to anyone...

since we speak about the lnb and the holder, here's some more pictures of it

***CROSSBONES*** · 28-01-2009

What size Fibo has he got? The other dish looks good, the polar mount looks nice and strong

**kamaleon** · 28-01-2009

90cm one, I'm still yet to find a second hand 120cm one

Do you think it's a good dish Crossbones?

***CROSSBONES*** · 28-01-2009

It does look good, but you may have a problem fitting an lnb to the feed.

I think they are manufactured in Poland

Thanks for the info mate, I'm not sure they're the same though. They don't look like it.

Crossbones, you're probably right

**pipino** · 29-01-2009

the LNB on it is from a very good LNB maker "California Amplifier" ,i never seen a wideband version on those LNBs,i bet it works very good too for DX stuff

**kamaleon** · 29-01-2009

you mean for feedhunting?

yes..if you want to call it

You'd soon mod an LNB holder ... the .8db/.9db wideband KU LNB's worth a play but you'd probably beat it with a £5 LNBf.

not always m8 ,specialy if you are playing with 4.2.2 or very low Symbol rate tansmission ,i find those OLD generation wide band LNBs more effective

its build very well and with care ..most of them are individualy hand ajusted in the labs..nothing compare to uncle chinachun

**kamaleon** · 30-01-2009

So you think this oldish looking lnb might perform better than the newer C120s like inverto, etc? Does it have a polariser (is that what one can see on the last couple pics)? I notice the neck of it looks square. Will it mount on a C120 round feedhorn? Sorry for the dumb questions

**pipino** · 30-01-2009

those LNBs have WR75 connection and not C120 you would need a polariser (mecanic better) in the same time it will do a convertion from WR75 to C120 (feedhorn or depolarizer)

**kamaleon** · 30-01-2009

oh dear sounds a bit too full on for me...

**pipino** · 30-01-2009

we are talking hard core DX-SAT stuff here my friend ..

**kamaleon** · 31-01-2009

I don't necessarily understand all the bits and pieces but I can at least tell that you're talking about hardcore DX stuff, yes
