LNB Skew settings

[ozumo]

Peak the skew using 11265 V & H, as the frequency appears on both polarisations it will make it easier to tell when it is correct - perfecting the skew will minimise interference from the opposite transponder.

A round dish will suit the Inverto LNB better than the Sky dish, but the the zone 2 will have more surface area. If you plan to motorise the dish then a non-Sky dish would be better, if staying fixed then a zone 2 + Sky LNB would be my choice.

...Which will be better?

You would better buy one dish Triax TD 88.
When in winter the snow covers half of the area of the dish, then you will still be able to watch TV.
It is better for the dish to be accessible for removing snow from it.
So, install it in the garden.

So have it on 11264 frequency when i positioning the skew to get highest reading.
The box snr 75% agc 86%
11.9db
11264 H 27500 2/3

11264 V 27500 2/3
Same results

Isnt sky zone 2 dish also 60cm so how is more surface area? A lot if people on ebay say its 80cm but is that right?
Some people say solid dishes give better signal but dont know how true that is either?

I know what ill do, get a sky zone 2 and use my inverto lnb. Then get professional to fit it. I did ask if there any fitter in this forum in the correct section but had no1 bite as yet. Strange, would have though there be many fitters in ere.

Ive been looking at the triax 80cm solid dish but im thinking is that too big. Dont want it looking too ugly. About a zone 2 sky dish size is alright. Any1 got a picture of zone 2 sky dish and a triax 80cm dish next to each other to compare size.

 

[LeBelge]

The dish is never too big. The mine is Triax TD 110. Here it is:



45°E - 39°E - 33°E - 28°E
Yes, the dish itself is skewed.

60cm dish is likely to be about 55cm x 60cm, a zone 2 is around 75cm x 56cm. Solid or perforated (mesh) makes no difference.

No need for professional installer.

Why is the dish skewed? does this bring any gain in reception?
Should all 28°E viewers skew their dishes?

I know what ill do, get a sky zone 2 and use my inverto lnb.

The inverto LNB has a normal feedhorn? If the feedhorn does not match the wider than tall shape of the zone2 dish, the effective receptive diameter of the dish is even smaller than the height of the zone2 dish (namely about height * cos(offset); but also depending on the 'opening angle' of the height of the dish towards the focal point).
I would choose a higher than wide (offset) dish..

Why is the dish skewed?

Because otherwise the multifeed will be tilted like this.



The satellites (45°E - 39°E - 33°E - 28°E) are to the left side of the north-south line.

No need for professional installer.

You are right.

Here is my way of finding an appropriate position in the garden. I can move the dish everywhere until the signal is strong enough.
I had to search a place for the dish (30°W) because of the big trees of my neighbor.



p.s.
the metal pipe is in poured concrete in the bucket

 

[rodscha]

and this is my elbow grease based motorised dish
with marks to position it into receiving various satellites..
80-ish cms..I would need 90-ish to get Albania,the rest comes in nicely including 7W!
1 shows lines for each satellite
2 the standing... & I should renew the wood palisade,too!
and some wood blocks help me adjust elevation too

Bonus point for the tube telly

Haven't seen anything like that before!

Nice, but the elevation is not the same for all the satellites.

Its screen is easier to see during a sunny day than the one of a tablet is.

 

[rodscha]

a series of wood bits allow me to vary elevation:
nothing for 13 & 19;
a thin one at the front for 10E a thicker one for 9&7E,nothing again for 7W./8W
and a thicker one even for 28E (which I did before the signal became weaker,which is when I chose to install a wall-fixed 120cms dish on the house
I can still get 25E with the help of the wood block,3cms thick,at the back of the antenna's podium
Basic...but it works!

Originally I thought of a motor,but was warned local winds easily make it lose its accuracy.
