1,2m dish Alicante 50m cable

[Captain Jack]

it would still be illuminating to know if installer optimised for 28.5 or compromised at 28.35 or went for 28.2E.

How much does it really matter on a 1m dish?

 

[superpascu2]

Dish is a Famaval LH110. Physical dimensions 120cm x 110cm. Electro-magnetic aperture is 105cm. I had one of those set up in Alicante city for keeping SNR data. Dish is too small for reliable reception.

The way I see it, if you knowingly agreed to have a dish installed that does not give reliable reception on all required transponders, 24 hours a day, 365 days of the year, you have no grounds to complain.

Thats right,

The instaler advised for 1,4 marafa, even took It home but the was no room and was my decision to install the famaval beceuse I always wanted to have a 28,2 dish.

And I am very Happy with the result. I have almost everything, BBC HD Channels, ITV,s, Channel 4, BBC radios...the only transponder fliquering is Channel 5 at some hours.

And all this keeping a 4 input diseqc which allows me having 19,2 and 13...and 70m cabling...

Think is a good performance taking into account dish size and set Up...

I Will try to improve It in near future following all your coments.

Thanks all.

Great fórum!

Pretty decent outcome for all those compromises

Well, we won't find out unless somebody tries, won't we?
isn't this a forum for enthuiasts endlessly fiddling with their installation in search of optimised reception?

 

[Captain Jack]

It was a genuine question. How much difference would one see within 0.3 degrees on a 1m dish, given its wider acceptance angle/beamwidth. I know results are visible on 1.2m...

Ah - i got you wrong then. Sorry.
My experience is that even at 105 it makes a difference if you are fringing. (Of course depending on quality of dish shape.)
When I had the CM100 up at work, I spent half an hour adjusing to optimise for 2F/G at the expense of 2E...

Strange..... now I have it, but it does not pull anything from 2e

Maybe it's because all the cleaning removes the special "fringe layer" of dust that the dish comes with after many years exposed to weak satellites?

 

[superpascu2]

Signal has increased in the last 2 o 3 days. Now channel 5 (the only one fliquering) works OK and I have better SNR in most of the frequencies.

The same for everyone?

Which is the worst mounth acording to your experience?

 

[superpascu2]

Hi all

I need urgent advice.

I have realised that I received Astra 2 E perfectly even the weekest transponder 10773H but I have problems with Astra 2 G .

That´s why channel 5 was fliquering and I dont receive ITV in HD or BBC HD in 11023H

I need your opinion. Having said that I am using a Fmaval LH110, dou you think it is worthy to adjust it just to Astra 2E and let receive all transponders in it or should I fix it to receive Astra E and G?

I am frighten to lose SRN in Astra E trying to get G...and lose for example 10773H which arrives up to a limit...

What do you think is better for a 1m dish as mine?

I ask because tomorrow the instaler is in our area so I could call him to fix it in that case...

Thanks

I am delighted to learn that you have realised the predicament.
2F and 2G are more difficult, not just because of the azimuth difference, but also because of higher FECs (5/6 etc).
With a 105 cm dish in DK, I would optimise for SD reception (Astra 2E) to provide maximum rain fade resilience.
However, if you live in a country where blue skies are the norm, I would probably adjust to 2F/G, and live with the fade on 2E.

At least you could try and see what it's like - ask the installer if he can adjust to 2F/G, and see what 2E is like...

Thanks ST1

If adjust to G means losing signal in E I could not do It because I am up to the limit in some SD transporders as 10773H or 10803H.

East Spain is Sunny but if you dont get enough signal even in Sunny days...you cant afford losing any db...

Maybe FAM LH110 dishes in my área should point only to E...Hope someone could confirm.

As the antenna is small, that difference of position is noticed, I know (Madrid with 90cm).
There is no solution on a fixed antenna, you will have to decide what you want and adjust in a compromise point.
The usual solution, bigger antenna, good LNB and do not forget to put low lost cable (very important).

In the motorized antenna compensated that difference of position, I have 3 satellites to 28'1, 28'2 and 28'3, with its relation of channels and then in Favorites, I have the channels that I see mixing the 3 satellites, it takes a second the Change of satellite.
---------
Al ser pequeña la antena, esa diferencia de posicion se nota, lo se (Madrid con 90cm).
No tiene solucion en una antena fija, tendras que decidir que quieres y ajustar en un punto de compromiso.
La solucion de siempre, antena mas grande, LNB bueno y no olvides poner cable de bajas perdidas (muy importante).

En la antena motorizada compenso esa diferencia de posicion, tengo 3 satelites a 28'1, 28'2 y 28'3, con su relacion de canales y luego en Favoritos, tengo los canales que veo mezclando los 3 satelites, tarda un segundo el cambio de satelite.

 

[superpascu2]

Now its clear, 110m fix antena must be adjust to 1 of the 3 sats. In my case I prefer E because I have everything in Sd and BBC in HD

Thanks guys

GI LNB works fine. Easily as good as black ultra. Dish is a 105cm. i.e. Famaval LH110.

Also, main problem here is noise from 26E and 30E. Small dishes just can't filter that off.

Signal data for Alicante is here. Signal report, Astra 2, 28E, Band-C and Band-D transponders

Story about July being the worst month of the year doesn't hold water according to my data.

Huevos, the link is very useful for me but could you tell me the location of the dish? You said Alicante but I think it is not exactly in the city center because yesterday the dish lost signal due to the storm before I lost mine in Alicante city center...so must be near Alicante...

Thanks

Hi huevos,

Is this dish still located in Alicante?

Last night de had really bad weather in Alicante with heavy rain and the were no signal loses in your data. I Lost some TP arround 1.30am

 

[superpascu2]

Hi all, I am experiencing a signal drop in 10758V and in 10729V. I am getting less signal in these TP than in 10773V which is supposed to be the weakest one. I started realising It one week ago. The other TP are still in normal values so realining the dish It is not the matter.

This is happening to me while in "huevos" signal data link happens the opossite (that is why I ask huevos to confirm the real location of the dish, but I got no answer) http://satellites-xml.org/signal-graphs/28E-SNR-table.php

Is this happening also to you? Any idea?

 

[Channel Hopper]

Has your installer changed the LNB ?

 

[superpascu2]

Has your installer changed the LNB ?

Yes, the set up is working propertly since last Summer.

This issue is happening since one week ago and only at certain hours as for example at 8.00am as I checked today. But I am not lossing any channel, It is just that I found strange to have less signal in the TP,s mentioned than in 10773V.

I have sometimes heard that the satellite sometimes moves from its possition and this issue cause signal drops in fringe reception areas. Dont know if this could be the case.
