Parabol or offset dish?

[skype]

I will setup two dishes for hotbird 13e and W3 7e.Which type of dish do you suggest for Turkey/Istanbul?

Re: Parabol or offset dish?

For 13 east the minum size for your country is 85 cm. offset it can be not enough when will rain hard I suggest if you can to mount 100 cm dish ever offset.
For 7 east, if you wanna receive just turkish beam 85 cm offset is also ok, but if you're intrested also to receive Europe A beam too, you'll need min 110 cm. minimum to get an acceptable signal.
Here you can watch beam coverages of 7 east:

And here is the list of 7 east satellites for various beams so you can decide if are intrested or not to receive Europe A beam (the most wake spot in your country):

I would recommend a 120 cm offset dish.

with a disc of 120 cm and above will be attached you can get coverage of several satellites with this dimension

Of course is always better to set up a big dish, but it is not possible ever, also he needs to set up 2 dishes so he can save some money using 1 mt. dishes. Signal he wanna receive are not weak signals.

What do you suggest for Astra? As I know, for Turkey, we need very big dishes to get proper Astra channels.Please comment.

For Astra most depends from where you live, in north west Turkey the signal is good, but going to Ankara it decrease much. Watch this footprint attached, if you live into zone covered by blue pic, you'll need just 120 cm dish, if you're outside this zone you'll need 180 cm or more, it can't be estimated, you just need to test because you're out of footprint there.

I think you could get 13e even with 100cm if it is setup good.

I live in the second yellow gradient layer.But once here in local, people had too much difficulty with Astra about 3-4 years ago.I just wanted to know if thgere had been any improvement in the coverages, but it seems 180 or more is a must to receive the most used beams on this sat.

For hotbird, most channels can be received from this reagon with even 80 cm dishes.But it must be setup well though.

most of astra satellites changed in recent years. you needed a very big dish 5 years ago. but astra 1k, 1m and 1L are new satellites and you can receive their signal using 90cm antenna. only old satellite there is astra 1H. and you will need around 2 meters dish to receive astra 1h.

Re: Parabol or offset dish?

its depend on your location instance i live in iran and just get astra1m but i heard if i want to get 1h i need 2 meter diameter dish with strong lnb but i think you can get astra 1m and 1h easily

Re: Parabol or offset dish?

Your location will decide the footprint.
Your footprint will decide the size.

With most footprints of today and Ku band transmission, up to 1.2 meters offset dishes will do.
With very weak footprints, a lager dish is required and in that case, you go for a prime focus.
Above 1.2 meters, an aluminium or netted dish is advisable because of weight.
