1,8m pööratav offsett tõesti ei ole mõtekas maja/hoone seinal, kuna tuleb teha päris olulise suurusega ja tugevusega kinnituskonstruktsioon.
1,8m mittepööratv offsett (ka multifeed`ga) võib küll olla kinnitatud maja/hoone seinale, kui tema keskne LNB on suunatud 28,2E-le, sest siis antenn jääb tõelise lõunasuunaga ristiolevale seinale väga lähedale ja on lihtsamini kinnitatav (kuna ta jääb peaaegu paralleelseks seinaga), sest 28,2E on väga lähedal tõelisele lõunasuunale. Antenn oleks ka tublisti vähem mõjutatav tuulte/tormide poolt kui katusel asuv antenn.
1,8m otsefookusantenni ei raatsiks multifeed`ga lörtsida.
Vastuseks kraps`le teemas Ajutised vabad kanalid:
0,8m antenn jääb 28E jaoks ikka väikseks juhul kui vastuvõtukoht ei ole soodsas kohas Saaremaal.
Paremaid tulemusi annaks 1,1m antenn korraliku LNB-ga ja täpse häälestusega.
Siis oleks mingisugunegi ilmastikukindlus.
0,8m antenni jaoks soovitaksin kas 19E või 13E. Nendel sattidel on vaatamist küll.
Mina eelistan enamvaadatavate teenuste (nö. kanalite) nägemist 24/7 ja seetõttu ei soovita kunagi minimaalselt võimalike mõõtudega antenne.

ASTRA 2G LAUNCH POSTPONED TO 28 DECEMBER
Russian space news agency federalspace.ru reports that faults were found in Astra 2G's launch vehicle, leading to Thursday's launch to be postponed. TASS now reports that the Yamal 401 mission scheduled for 12th. December will be the next launch from Baikonur. 2G will follow on 28th. December.

eelnev uudis:
2G-The hugely expensive satellite, designed to broadcast to the UK, Europe, the Middle East and Africa, sits atop a Proton rocket, of a type that has suffered two disatrous failures in as many years. For the following 6-8 weeks, If things go according to plan, Astra 2G will be tested in an orbit some distance from its final destination at 28.2º east, from where it will carry BBC, ITV and Sky services, beginning in early 2015.
However, if there is a repeat of the previous failures, expect a fireworks show of a type you can't buy at the corner shop. An earlier disaster was caused by incorrectly-installed guidance components, which led the Proton to plunge to the ground shortly after blast-off (below). The parts had been installed upside down. Human error was blamed.
------
No-one knows what SES has planned for the channels it carries for UK broadcasters. We know that the BBC intends to add HD to all BBC One regions, so this may happen next year. Less certain is whether Sky will move more services to the UK-only beam, resulting in the kind of loss which so upset many in mainland Europe last February. Sky turns a "blind eye" to the widespread use of BBC One HD logo Sky cards and boxes outside the UK. (Breaking its terms and conditions). So much money is made in mainland Europe from the grey market that Sky would find it very hard to cut off the estimated one million subscribers in mainland Europe, and then only if its hand is forced by rights owners. Premium services such as Sky Sports, Movies and first-run drama from the US are sold on a geographical basis. Sky maintains a charade that their channels can only be received in the UK, and pays a little less as a result. American studios know what's going on, but don't kick up a fuss, so long as the deal is lucrative. The pretence has grown thinner in recent years, and may one day be unsustainable.
As for the second rumour, Sky has always been available all over Europe. It's just the BBC and ITV which left.

Ja annab ka eestlastele natuke lootust, kuigi Sky 28,2 E ikka eriti Eestimaa antennini ei jõua

Põhja-Soomes ,Kuusamos, Astra 2E 12480 V on vastuvõetav 85cm antenniga (Triax TD88).
I can't quite believe it but I'm near Kuusamo, Finland by the north eastern border with Russia and with an 85cm dish (TD88), Black Ultra single LNB and a Pace 2600C1 I'm picking up 12480V (2E Europe) clearly tonight, no breakup.
