Stanner It seems to depend on whether you mean an LNB with twin outputs or twin LNBs on the same dish.
So far as I understand it (and having a dish with a two LNB set up sat in my garden) a two/twin LNB (correctly set up) allows you to tune one dish to two different, but closely aligned, satellites.


However a single LNB that has 2 or even 4 outlets is suitable for use with "twin tuner" decoder boxes and does as said allow one channel to be viewed whilst a second channel is recorded as with my Humax box and the use of two boxes in different rooms.

The two/twin LNB/2 satellites set up requires some special changeover device/software to make it work and allow you to choose which satellite is used.
That I know nothing about - the dish was owned by my late Bro-in-Law who was really into that sort of thing and at one time could tune into 5 or 6 different satellites from his home in Essex.

Mrplodd If your Avtex has a digital FreeSAT receiver built in then that's (other than a dish and a signal meter) is all you will need! The Avtex receiver will pick up everything a Humax or similar FreeSAT box will.

You will NOT be able to pick up any FreeVIEW stuff once you are out of the UK (other than a bit whilst you are near Calais as it will still pick up a signal from Kent.)

The only reason you may want more than a single LNB is if you have a recorder, two LNB's enable you to watch one channel whilst you record another. (Same as a Sky box)

I am curently near Avignon and I won't bother to try and get any Freesat stuff on my 60cm (standard Sky size) sat dish, so I will just have to "Catch a few Ray's, eat some cheese, drink some wine, and just chill,man"

Doh!,

Didn't see there was a second page,!!!

aldershot1 Before anyone bothers to respond to my latest questions please dis-regard as I found a very lengthy string in the "Freeview & freesat" section of the forum that tells me all.
Thanks anyway

Penquin John,

may I suggest that you pay up the £12.50 and subscribe as if you could use the search facility you may well find many other answers to many questions.

Being a full subscriber also means that you can use the Personal Messages and seek responses direct from those who offer advice, there are other advantages but for less than 3.4 pence per day it will probably represent the best expenditure you will ever make for your MH. I joined when I had a problem years ago and got helpful advice within 20 minutes that allowed me to solve the problem - and avoid a 100 mile return trip to the dealer as well as workshop charges.......

Free to air will ONLY work in the UK or perhaps a few km into the rest of Europe, but certainly not very far. So your inbuilt decoder will be unable to detect any UK free to air channels.

So if you ever intend to visit France, more than perhaps 20 km from Calais, then FreeSat will be the only system that will pick up any BBC signals.

Single or twin LNB - not really a major decision IMO as you can only watch one channel at a time, a twin LNB allows you to watch one and record another if you have a suitable decoder and recording system - switchable means that you could switch between 2 satellite inputs, my simple question would be WHY? unless you are determined to follow specific channels at the same time it would be of no value IMO. So I would stick with a single LNB which makes the srt up easier and quicker.

If your Avtex TV can decode satellite signals then free to air is a waste of time - the satellite is available throughout the UK and Northern parts of Europe without much playing around, the only problem will come if the satellite dish cannot "see" the satellite e.g. if you are surrounded by high trees or buildings, in which case the free to air signal may be much stronger - bt it would need adjusting every few miles as the aerials it is transmitted on will differ.

I hope that helps, watching TV can never be guaranteed in Europe, but you stand a good chance with FreeSat and no chance at all with free to air if more than about 20 km inland..... (obviously some may say further but that is a ballpark figure).

aldershot1 The last questions on this subject (i promise.). I have an Avtex L187DRS TV that I am able to directly link to satellite.This removes the need for a separate receiver box. I have looked everywhere and have not been able to pin down the actual channels this will provide and whether these channels will diminish as I go into Europe.

I assume that when TV is connected to terrestrial ariel I will receive Freeview but what do I get when connected to the satellite? Also what added value will a Freesat box give me over the Avtex inbuilt receiver??

Lastly I have been offered both a twin LNB and single LNB with switching device if I decide on the extra box. What do you consider the more effective option?.

aldershot1 Thanks Davy & Dave it is much clearer to me now.

Penquin Both are digital broadcasts transmitted via different routes as said, the aerial route has a range of perhaps 40 miles maximum from the aerial, but there are "repeaters" all over the place to ensure a good signal in most areas.

The satellite route goes via ONE part of ONE satellite which has been "tuned" and constructed to give a "footprint" that fits over the UK and not much further (or so the broadcasters would wish - however that is impossible to achieve so they have gone for the minimal possible.

Reception depends upon the size of the dish reflecting the signal onto the receiver (the LNB actually picks it up after it has been bounced off the dish onto the LNB) - so it's a bot like a torch in reverse - in this case the signal is being gathered in and concentrated, whereas in a torch it starts as a "concentrated source" (the bulb filament) and is then spread out to give the beam.......

The actual footprint looks a bit like;



On that picture the figures express the diameter of the satellite dish that theoretically MIGHT work there.... but there are other factors involved as well..... so it is not as easy as that......

If you want to find out what channels are broadcast on which part of which beam, this page will guide you....

Which beam for which channel

In order to watch the BBC, ITV, C4 etc. you will need to be receiving the UK Spot Beam.

TeamRienza Freesat is received via satellite and freeview is received through a standard tv Ariel in your house.

Have a look at the freeview and Freesat sites for more info.

aldershot1 Thanks everyone tour thoughts have been most useful. One last question ' what is the difference between Freest and Freeview?'

peribro I can't see it's worthwhile buying the Sky Freesat offering as it would be cheaper to but a Humax Freesat box - or other make. Sky's £175 charge includes installation which you won't want. Alternatively if you have an old Sky box that you don't use then connect that up instead - that's what I use.
