7.3w Eutelsat 7 West A[formerly AB7 & the leased TPs of Nilesat 104] These dish sizes are minimum & should give reception most of the time but make no concession for bad weather or local interference margins & one should calculate a lager size if a higher margin is required. Dish sizes are based on surface area so width + height / 2 & not the offset measure or based on any manufacturer's or reseller's sizes or model numbers. These figures are also based quality BCS or Purplesat installations or equally quality installations. Any poor products &/or poor installation practices will alter these figures. Figures do not include all beams/ channels. Channels vary in power- these figures are based on the weaker but popular channels [movies & sport].. DVB-S2 & OSN channels require c. 20%-30% larger for the same lock level.
7w Nilesat 102 sizes for the reception of the strongest verticals start at c. 10-20% larger on area for areas A B C & much further north of zone C & the signal drops off quite sharply. Reception of more channels from Nilesat 102 in A B C (mid to low power verticals then the first horizontals to mid & then the lowest power horizontals) in zones A B C require increasingly larger dishes to all channels of estimates of 1.8m 2.4m 3m 3.2m 3.4m 3.6m [A B C] & larger for reception between 11am & 2:30pm- the high solar noise period on the reflector at the satellite.
NB: Reception figures for Nilesat 102 have worsened due to interference from the more powerful & more populated Eutelsat 7 West A raising the noise floor on near noise floor reception situations - this is not as noticeable in stronger situations as the change to the noise floor is further beneath reception breakup.

26e/ Badr4 dish sizes are generally a % smaller on area than Eutelsat 7 West A @ 7.3w - however- on smaller dish size areas it then requires the narrower beam width of the larger dish due to the close by powerful 28.2e UK Sky/Freesat services, therefore the smallest size** may need to be adjusted up to 7.3w figures below 80cm for this reason. 7w does have 2 satellites either side [5w & 8w] that are strong in the UK but far less channels so their noise image on 7w & 7.3w is different & more selected.

IMPORTANT NOTES About DIFFERING BREAK UP LEVELS ON DVB-S -QPSK DVB-S2-8PSK/- most HD etc.. 2/3 3/4 & 5/6 FECs etc.. & daily sun effect signal cycles.
These figures are for good installations in average interference areas & average fringe EIRP for SD/ DVB-S QPSK reception with SR of 27500 & 3/4 FEC- areas can differ on interference either with interference quiet rural, coastal locations or interference noisy large area [city &/or industrial influence] locations & signal cold spots & hot spots of fringe reception.
In general figures are for DVB-S/ QPSK- FEC 3/4 & Symbol rate of 27500 .... allow 10% larger surface area for FEC 5/6 & 10% smaller for 2/3 FEC & 30% larger for 8PSK on DVB-S2. Some HD on DVB-S can be received with 20% smaller/ some 8PSK require even larger even though the signal looks similar - very high or very low symbol rates can also add another variable... in the above case it's higher (& lower) break up levels we are describing & not signal or quality levels so if a dvb-s channels @ 3/4 fec 27500 st qpsk breaks up at 50% on your receiver - an 8psk of the same strength may actually break up at 60%.

Sky Z1 dish (N France) Z2 / 60 to 70-80cm (mid to S France) 80cm+ (Northern Spain) & generally 1.2m to 1.8m around Spain
except 2.4m in Alicante/Mercia region & inland towards Madrid suffering from a built up corridor area noise of industrial/ commercial & urban developments & between 2 airports - 1.8m in parts of Madrid. 3m- 3.6m+ on Canaries islands.
These figures are for 24hr reception (see FRINGE RECEPTION CYCLES below) including reasonable adverse weather conditions at reception site or up-link site/s & are based on good quality offset or prime focus** satellite dishes professionally & accurately installed, good cabling, sensitive LNBs & sensitive receivers. Any deviation in quality of install - particularly the dish's integrity can have a dramatic effect on these figures and local noise exposure or sheltering issues may alter these sizes in any given area as will the patchy/ irregular nature of fringe signals that are not usually a smooth decline from the main footprint but display peaks & troughs that can mean that several miles further away from the footprint and the signal can improve. **A prime focus dish will have an effect on intra satellite separation due to it's wider beam width & deeper noise sheltering of the LNB.
FRINGE RECEPTION SIGNAL CYCLES
THEORY
Most satellites on fringe reception show a daily cycle of signal to noise increase & decrease and the main reason is the position of the sun.
On the old now removed Astra 2D** beam (mostly the UK's FREESAT channels) the signal goes up and down on a daily cycle as with most satellites in fringe areas outside their official FOOTPRINT. This is mainly due to the position of the Sun acting on the position on the Clarke belt of the satellite and the position & aim of the TX (re- transmitter) antenna on that satellite & whether the Earth & it's atmosphere & outer ionosphere are also shielding or deflecting the solar stream or not or it's position is assisting the solar stream to hit the Tx (this can be visualised with the path of a smoke trail in a wind tunnel and a spherical object representing the Earth).
The time & sun rise and sun set on the Earth on the ground is not the issue but the nearest equivalent of sun rise & sun set at 22000 miles over the equator at, in this case, 28.2e and the fact that sun set & night there is more of an eclipse or fowling of the solar stream towards the TX by the Earth & it's atmosphere / ionosphere plus shielding from the back of the satellite & the TX antenna.
ASTRA 2F @ 28.2e aims to the UK from 28e at 22000 miles above the equator (the Clarke belt or GSO) so as the sun rises the signal is better as it's behind the bulk of the satellite & the antenna so it's good early in the morning - add a couple of hours to the time for Spain that should see a good signal to about 10am until (@ 28e on the GSO) the sun passes it's noon and gets at the front - business side of the TX antenna- then it starts to go down as the sun travels more & more westward and has a more direct aim into the TX on the antenna and eventually starts to set (@28e on the GSO remember) that's about 2-3am Spain time when the Earth then starts to block some of the noise from the Sun. So smaller dishes than recommended will receive Freesat channels in Spain at the best times and the bigger dishes are needed for the worse times.
Lots of other things can effect the signal. The sun on the RX of the satellite has a smaller cyclical effect as RX's are more sheilded -ionized layer fluctuations from the moving position of the Sun's solar stream radiation direction & it's effect ionizing it, local noise from towns- industrial areas & heavy populated areas, overhead power & telephone lines, airport radars & radio communications, power supply fluctuations at the transmitter & receiver, battery power on the satellite compared to solar power and heat in the day compared to cooler nights on LNBs & receivers & transmitters & the effect of direct solar outage on the receiver's or transmitter's antennae can all have a daily cycle effect.
There are obviously other non daily cycle effects such as weather- rain, snow, cloud, fog, extremes of heat at the uplink or receiver site and fluctuations in solar radiation in general usually caused by solar flare increase.
7w NILESAT 101 102 & AB4A/ AB7/ EUTELSAT 7W A /NILESAT 104/ NILESAT 201 These rules apply to 7w reception in the UK (Nilesat 101 102 & AB4A / AB7/ EUTELSAT 7W A / NS 104/ NS 201) - but all the variables need altering to 7w to get the right result.... Firstly it's at 7w not 28e so there's a time shift (it's UK time or just after), it's a broad east aimed over the MENA region, not a tight west aim just around the UK as with 2D... so as the sun rises the signal goes down mid morning as the eastern rising sun aims into the eastern aiming MENA beam TX's @ 7w- by mid day (@ 7w & UK in this case) the sun gets behind the satellite & the TX so the signal starts to climb and gets stronger as the sun travels westward through the afternoon and evening and late at night & also goes behind the Earth so the best time for 7w in the UK is in late evening and through the night to early morning- the worst time being 11am -12noon.
26e BADR 4/5/6 26e on the other hand has very similar MENA beams to 7w yet the daily signal to noise up & down cycle is less pronounced due to 26e pointing almost directly down on the MENA region from 26e on the GSO this shielding it's TX from the sun more & more of the day but 7w's more eastern aim from over at 7w is more open to the sun's effect in the morning and is much more shielded later on by the back of the antenna, the bulk of the satellite & later on still by the Earth joining in.
Apply all these rules to any satellite & it's fringe reception cycle reports & the equation will give the cycle at fringe that is seen- examples are AMOS 4Win the UK, 4.8e Nordic beams in the UK, 1w Nordic beams in the UK, 23.5e Nordic beams in the UK, 16e in the UK etc.. all act as predicted from the above variables.
EASY SATELLITES TO RECEIVE & WHY
This is a typical EASY reception in the UK... as you can see the signal is very strong in the UK - this sample footprint also covers most of Northern &
Southern Europe- going into Russia in the East & North West Africa and the Canaries.
What to look for is satellites with good signals that goes into the UK on footprint maps for smaller dishes- (most are listed above as strong signals) and medium dish sizes (70-1.1m) will receive more that don't quite come into the UK and larger dishes (1.2- 3.6m) will receive signals from satellites with beams quite far away from the UK... but some you will not get - India beams- S & C Africa beams US beams S & C America beams - even though you can see them and they are not below the horizon... about 75e to 75w absolute maximum from where you are - more with height above see level and usually limited to 45e to 45w due to hills, trees, buildings & ground noise off the Earth.
