There has been a severe Signal drop since Saturday.
The Possibility of this was suggested by the behaviour of 2 F last year when the Summer was very poor for reception in our area.
It is for this reaon i have been advocating the LARGE Dish sizes.

As most will have noticed, signal strength has been reduced for quite some time.

Many of the success stories above are no longer working.

Talking to a local installer, the following are working OK :

30250 Combas 90cm with some pixelation in bad weather
30250 Salinelles 1m no problems
34160 St Bauzille de Montmel 1m no problems

It is likely that the 'Summer Low Signal' will be a regular feature, with reception picking up in September running through to March April. It is therefore imperative when choosing a Dish to follow the advice from those who have been monitoring the situation since Dec 2012.

Ie where possible install a Dish a size bigger than the minimum. ie.

Montpellier to Beziers a Triax 110 with Opticum 2x or 4x
Beziers to Limoux a Gibertini 125 with Feedhorn
Limoux to Perpignan a Gibertini 150. with Feedhorn
South of perps. a 180.......with Feedhorn.

I have been advocating this for Months, and have in fact decided not top install Dishers until September when we will have a definitive List of sizes for any given location

Yes, that was why I thought it was worth checking out progress as many of the early happy people are no longer happy !

No sure I follow this. Doesn't lack of cloud = good reception?

Reception has been excellent (88cm Triax) for the past week but agree a bigger dish is more robust when a cumulonimbus gets in the way.

I am not talking about the day to day variations in reception due to the actual weather.

We have been monitoring the Signal of Astra 2f since Dec 2012 and both Astra 2f and Astra 2e since Feb 2014.

During the period May -September 2013 the signal from 2f was seen to suffer a severe reduction.

Bearing this in mind, my advice was that both 2 e and 2f could suffer the same fate in the same period (May - Sept) 2014, with a recovery expected in September which should last until April 2015.

It was for that reason that i offered advice on Dish Sizes and actually decided myself not to install any new Dishes until i had monitored the Signal through this Summer.

I tried to warn anyone about relying on the 'signal' of the day during Feb/March/April as a guide to what size dish to install.
Unfortunately there have been many people caught out who have had the wrong size dish put up, installed by people who did not have any idea that this might happen.

In my area the local French installers soon started installing the wrong Sized Dishes, the wrong makes of Dishes and the wrong Types of LNB's....... With the result of course, most are now not working satisfactorily.!!!

I have also been warning people about makes of dishes not performing the same and the same possible 'Pitfall' of using the wrong LNB.

montgolfiere - is there more information than just observation data here? From what you write I'm not sure how one year (2013) of a lower signal strength May-Sep means it will be repeated in 2014 or any other year. We're already well into June 2014. Why should it be an annual cycle for example.

Fully sympathise with the dilemma professionals and their customers face at this time. Our friends with the "Parabole 83cm Composite marque TONNA Dimension réflecteur : 79 x 88 cm Gain à 12,75Ghz : 38,7dB" in the village have been experiencing a somewhat flaky reception for some time.

I am afraid there are no 'Official data feeds of information', because none from SES/SKY/BBC are interested in anything other than reception within the British Isles....so we have only our own @expertise' and 18 months of observations to go on.

2013 2f May -Sept signal drops.
2014 May into June (and by my estimation into September) 2e and 2f Signal drops......

Put up any dish you want.... but my advise would be that it is likely to 'assume' it may happen again next year.
IF i am wrong, so be it: but at least you will have a 'too large' Dish rather than a too small Dish that doesn't work.

'so you pays your money' and maybe 'you takes your chance' if you want to ignore any or all of this......

All I can say is that the signal here has been as good if not better the past 10 days than it was in April. Perhaps the shape of the footprint changes from May to September?

Current info about dish sizes ...

Above the purple line works with a 1m dish

Between the purple and green look at 120cm dish

More : http://goo.gl/maps/2KUSY

Problem is we don't know future beam pattern or signal strength. Buy a bigger dish or wait ?

I am afraid that map is not accurate enough.

Montpellier 100cm. Gibertini
Beziers 110/120cm. Triax /Metronic
Narbonne / Carcassonne 125 Gibertini with Feedhorn
South of Limoux 150 Gibertini with Feedhorn

Make and Model of Dish and LNB are CRITICAL. Cheap Dishes = Crap Signal!!!

The map looks as accurate as the data points to me. 110 cm dish near Narbonne with good reception for example.

How would you draw the line?

I am just reporting our experience as the signal has varied over the past 4 months. A 110 is not big enough at Narbonne to cope with the 'Lows'.

Not much map action below the green line, presumably there are no reception problems down there ........

People tell me today that the signal is better and they are getting BBC channels back.

Does that make sense ?

Unfortunately this is to be expected. The signal is behaving as 2f did last year. periods up, periods down. Our Dish size recommendations are designed to cope with these 'Lows'. This 'variation' is likely to continue in September when hopefully the signal should improve for the Winter.....

it has been possible to watch the Football on Filmon. Probably not wise to openly publish this, so PM me if you want the 'work round'.

My old installation has started working again this weekend.

Stronger signal or the rain has washed off some bird droppings ?

The signal is, and has been for a few weeks, 'Up'.... how long this will last for, is of course the 'Billion Dollar Question'. However some 'improvement' after the Summer is expected so hopefully this increase last until then .

But... Please note:

we would expect the signal of 2e and 2f to drop in April/May/June 2015 as 2f did in 2013 /2014 and 2e did in 2014.
