120cm Gregorian

lloyd21

Hello,
Does anybody know where I can find a 120cm gregorian dish, I found a 90cm Master Focus (FIBO) but I think im going to need a touch more gain.
Thanks

Why a Gregorian?

The cost over a standard dish is unlikely to be worth the improvement

I dont know of any decent ones out there , stay clear of Spanish ones

There is a very fine line between "hobby" and "mental illness"

Likvid

A U.K dealer recently sold his 120cm Fibo dish last week for £350, it was used.

They aren't made anymore since 8 years back or so....

Thanks CH,

My understading is that a 90cm equates to a ~110 (Likvid mentioned it I think), So a 120cm would equate to roughly a ~140/145??, reasoning being is I live in a apartment and the Biggest I could get away with would be a 120 MAX.

Thanks Likvid,

I got a quote for 350E from satmuller for a 90cm with motor, I really want a 120, Do you happen to know any Backyard specials?
How would I find out cost freight from Germany to Japan?... DHL?

I bought my Fibo 90cm from Satmueller a year ago or something for that price.

Forget the Fibo H-H mount, it's useless, i hate it.

Buy it with the AZ/EL mount instead and then buy a Moteck 2100 motor or even a Jaeger 36Volt motor if you want that instead.

I don't know anyone selling their 120cm, they are very sought after in the market and Fibo never produced many.

Reason i bought the Fibo was because i couldn't have anything bigger on my balcony, otherwise i would have bought a Channel Master 1.2m dish for over half the price and get better performance.

Read my thread about the Jaeger SMR-99G mount i bought to the Fibo, it works perfect.

Thanks Likvid

He quoted my 195E for the 90cm Az/El fixed, Right now I have a Pansat PM900 for my rubbish fortecstar, Here is a quick question I live in Yokohama, Japan I am looking to get Agila2 out of the Phillippines, what would a 90 get me, I not really good judgeing these types of things

139E 38N

I can afford to get a similar set-up as yours Likvid, How far could I see do you think?

Likvid

You should receive these channels at your location and the Fibo 90cm dish.

Agila 2 says a 2 meter dish is required at your location.

Here is a picture of the 120cm also....

Yes thats the one
Thanks for the list Likvid,
I pull all that down with my fortecstar...so not much of a difference with a 90, how is the FIBO for dxing?

FYI: Here is a Japanese DX'er Spectrum Analizer screen shots for Ku

Fibo is great, high quality.

I can't get a better dish right now in my situation, i can get from NSS7 at 57 East to Intelsat 801 at 31.5W.

I receive even weak analogue signals from Arabsat 2B at 30.5 East with my low threshold extension set to max, comes in at 1-1.5dB C/N approx.

lloyd21

Thats incredible!!! In your current situation, how would a 120 prodelin or the like compair?

I can go as high as a 120 in my apartment, What would you recommend for me, my guess is I could get the most gain out of a FIBO or cassegrain, money is not necessarly an object currently, unless it just outrageous

Likvid

Andrew Type 120 is the dish of your choice if i was in your position and couldn't get a Gregorian Fibo 120cm.

My dish is comparable to a Triax 110.

lloyd21

http://www.sepatriot.com/pop_up/10_12_dual-.jpgIs this a georgian from patriot?

Likvid

Yeah it's Patriot, don't know how it performs, doesn't seem like the high build quality of Fibo.

lloyd21

Reason I asked is Patriot has various sizes for these dishes, under there tx/rx antennas...I searched the forums and patriot really have a bad rep. on her...or any forum for that matter...unlike Jonsa for Fortecstar.

They have these in 1m and 1.2 georgian "style" not sure if its a true or not. It may be an alternative for somebody that would need one.

Likvid Do you know if they make a cassegrain at 120?

Likvid

Yes they have a 1.2m Gregorian dish also.

Here you have the manual

Likvid

Goosh....it's performing worse than the Andrew Type120 or Prodelin 1130 dish.

lloyd21

Here is a spec sheet comparison- For those that care

Looks like andrew wins hands down.....Anybody have a spec sheet for a Fibo?

lloyd21

According to this guy, Fibo's are being sold as Master Focus
www.satellite-calculations.com/Fibo/fibo.htm


Fibo 90 Spec sheeet
Gain @ Mid 40.9
Efficiency 82%
Cross Pol <-30db
Beamwidth 1.57

Likvid are these accurate?

Channel Hopper

The Andrew is a Channel Master item

There is a very fine line between "hobby" and "mental illness"

Likvid

No.

40.9dBi is a bit optimistic, i would say about 40.3dBi or something.

lloyd21

Also would like to throw Katherin into the mix, Does anybody have any experience???



http://www.kathrein.de/en/sat/produc...ad/cas_018.pdf

Decent Specs also:
Gain
10.70~11.70 = 41.5
11.70~12.50 = 42.15
12.50~12.75 = 42.5

The Fibo 120 gets
Gain @ 11.7 = 42.4Dbi

Looks like the fibo is a touch better, but unavaliable.

Likvid

That's the CAS120 Offset dish, very good dish, probably the best 120cm on the market but it will cost you a arm and a leg.

The dish goes for around 400 euro and the AZ/EL mount for around 300 euro.

Just look at the build quality, it's amazing, it's commercial quality and you get what you pay for.

Likvid

Look at Stefan DX site, click on the images and you will see his CAS120 setup.

Nice eh?
