Getting Started On C Band

[hexah]

To be honest my dream dish is sat in the shed waiting to be installed, I have had some great fun with my 1mtr orbitals and now still having fun with my 1.2 just on ku,

I am sure I will never run out of things to chase/find etc with the 1.8 with c band ku and maybe ka, also it will be able to track inclined satellites, I will be as happy as a pig in muck. I cant see me ever wanting needing anything bigger.

Being in the same situation (except if I even mention the big dish my life will come to a violent end) I can assure you it is a massive improvement from 1m to 2m.

When you get the 1.8m up you will wonder wtf you were doing taking so long to get it up.

Although you will always daydream about bigger I think a solid 2.4m or mesh 3m are the realistic maximum.

That said there is a huge amount of stuff that will appear as marginal signals in the right weather conditions on 1.8m and if you have patience and use a thick threaded bar you can zero in on very weak signals just be careful where you put your hands.

Pretty sure he's talking about the Jonsa dish which are petalised. Would want these even for C band. Channel Master all the way

Yes, its this one http://www.jonsa.com.tw/english/products_detail.asp?pid=53

C-BAND Gain @4.0GHz 38.39dB ;)

I think you mean you would not want a toilet paper papier mache dish!

Some were virtually given away on fleabay so for experiments they are o.k. for people who could put up with them.

Don't buy unless it is at a giveaway price that's all they are worth.

Well moneys been/is an issue to start with hexah getting thing together, and I still need around £700 and that's if I am successful making my own mount, if that fails I will need about the same again for the mount,

I could go down the credit card route but I don't want to do that apart from our mortgage we are now dept free

That said there is a huge amount of stuff that will appear as marginal signals in the right weather conditions on 1.8m and if you have patience and use a thick threaded bar you can zero in on very weak signals just be careful where you put your hands.

The dish will be on a dual axis polar mount so I should have no problems zeroing in on these weak signals, this is one part of the hobby I love along with others, I guess you don't look in the fringe area, I am always reporting chasing reports from this section,

I do very well with fringe with the 1.2 and I do have the patience for chasing the signals,

So you think the 1.8 will just blow the socks of the 1.2, I was expecting a little gain but I did not realise how much, if so I am in for some good DX

Are they a one piece dish st1 please.

As CJ says these are the petalised (6) Jonsa ones.
I bought one as my first large dish.
Mechanically flimsy, underperformed, and rusted after two weeks.
Was destroyed a couple of months later by strong winds.
But was cheap at 99 quid from Maplin (of all places)...
Now I know better for Ku band...

 

[Captain Jack]

Yes, I did mean 'wouldn't'! It's not a dish that's worth my time....

And Martin, I think your efforts of making your own mount will definitely pay off. It looks sturdy and, to be honest, as long as everything is straight, there's really not much to go wrong.

I am very much looking forward to your chases next year!

If anyone has a 2.4 Jonsa/FS kicking around I'll gladly take it for experimenting on C Band. It's impossible to find a used one at a sensible price because there's always some idiot who thinks it is worth £100+ to watch some dodgy football channel on Ku. I've compared the C1w against an ESX241 and found them pretty much identical, each had parts of the band that they were superior in but there was no clear winner.

Sorry but negative post will be deleted, when I've tried and failed fire away .

So people aren't allowed to post their findings? And what I said is a fact; a 1.2m in C-band has the performance of a 40cm in Ku-band. Check the gain figures if you don't believe it.

I know what you are saying is fact and a small dish is hard to get C band on, i have been messing with satellite for long enough to know this and read it hundreds of times,

It does not give peeps any encouragement to try it by negative comments, if I was to get one lock I would be happy,

There is at least two people following this thread that will be using small dishes,

I would like to run this thread without negative comments, if you want to go around being negative about small dishes and C band I will give you a link to another forum were peeps have got good results helping each other and been positive rather than pulling each other down, you can go there and cause trouble if you so wished,

But leave this thread out of it and let it run it course please.

Anyone tried 20E recently? - I got a few C-band tp's with a 1m dish when I tried it a couple of years ago.

I was hoping to have a go today and 20E was were I was going to try A/S after reading through your thread, until a neighbour knocked on the door asking if I was any good with plumbing, the rubber seal in the toilet system had gone, took me longer to fetch the part than to fit it, spoiling a mans Sunday fun.

As I have often said, the eirp / dish gain figures are for intended service areas. If anyone took much notice of that DX as a hobby would not exist.

I reported a few years ago with my Triax TD64 on a cold clear winters day I was receiving weak channels from the old 16e that were difficult with a 1m. Careful alignment was the important bit if I breathed on it the signal would go.

I've had similar situations watching the signal and the clouds on a nice summer evening faintest bit of cloud and lost the signal and seconds after the cloud passing the signal gradually coming back, that's what I call fringe

 

[Captain Jack]

Martin, 20E is the best one to try with a 1.2m - will easily get a few (if not most) channels from there with rain margin (not forgetting that C band signal are far less affected by rain than Ku and - especially - Ka band).

You will get some channels on 5W and a decent number on 40W. This should get you started

I am still soooo jealous for you lads about that My most wanted satellite and my results after 2 years: 1 lousy horsederby channel from Argentina (4045R)

Yes but you get so much from the eastern side. My C band dish doesn't reach beyond 26E and the practical limit at my location is about 68.5E. There's so much interesting stuff from 76.5E, 78.5E and beyond that we in UK will never have any hope of getting.

 

[Kveys]

Yep CJ i know. But that´s allways most interesting what you cannot get And yes, very nice feeling now when Australia plus (68.5E) my backround tellyvoice atm. And maybe next I will turn to some Maldive channel (76.5E).





But where are my latino channels...

Question for those who have actually had and used the Jonsa dishes..
I am well aware of the problems and failings but am actually considering buying such a lump ...and not for use as is.
Im considering using just the 6 petals of a 2.4 to be mounted on top of my existing ally pF (1.8) ...and discarding the crappy mount etc.
In other words ...re skinning my dish.
So to the questions..
Does anyone know the fd of these dishes ?
what are the petals made of ...?
I know they are flimsy at best but mounted over a solid structure and securely anchored ...it may well serve purpose in Cband..
It would not be used for Ku ..so accuracy isn't such an issue.
