Astra 2F+2E+2G (28.2E/28.5E) levi.
Re: Astra 2F (28.2E)
Sellega saab kindlasti 4,5 meetrised offsetid,pildid lihtsalt "kõvatamiseks" 

Sul ei ole õigusi, et siin postituses manuseid näha.

Re: Astra 2F (28.2E)
et tegelikult polegi mingit parabooli või offseti vaja.
laome aga piklikud paneelid üksteise otsa .... jne ,umbes selline nagu seal pildil.
selle antenni tutvustus:
This novel concept in antenna design developed
by CSIRO offers a unique solution to the future
needs of satellite communications. The CSIRO
MultiBeam antenna can access up to 19 geostationary
satellites simultaneously, in fixed or inclined
orbits (option), over multiple frequency
bands. It can replace a farm of conventional
antennas, each communicating with a nominated
satellite.
How Does It Work?
The CSIRO MultiBeam Antenna consists of two
reflectors in an offset Cassegrain configuration
and an array of feeds, each viewing a designated
satellite. Unlike the conventional antenna, which
has a single focal point where the feed must be
positioned, the CSIRO MultiBeam Antenna has a
focal surface on which up to 19 feeds can be
placed.
In this antenna, the reflectors are specially shaped
and strategically positioned to broaden the
scan region along the geostationary arc. Within
the scan region, an almost constant antenna gain
is achieved. All the beams have a cross-polar
performance better than –30 dB and sidelobes
within the ITU recommendations. The CSIRO
MultiBeam Antenna design offers a very compact
structure compared to other multibeam configurations
currently available.
The MultiBeam Antenna can communicate simultaneously
with a number of satellites within two
degrees of each other, a separation small enough
to operate with geostationary communications
satellites well into the future.

Mulle mahuksid Hiiumaale, endisele kartulimaale, smile196 kõik need 5-6 antenni ära (mis pildil olid) ja maa oleks jälle kasutatud!
Re: Astra 2F (28.2E)
Mu ühel tuttaval oleks kolm kärbest korraga: ettejääv mets maha müüa, seega kohe ka maa ülespanekuks olemas ja pakk raha ka seadmete ostmiseks.
Re: Astra 2F (28.2E)
Esiteks selliseid antenne vaevalt keegi eraisikutele (siin) müüb kui just mitte ise teha teiseks kui olekski mingigi võimalus midagi sellist siia aretada ma kardan et sellest rahapakist jääb ka talle väheseks smile174 Ma pole küll kuulnud et Eestis eraisiku käes midagi sellist oleks,Pärnusse vist sai mingi larakas kunagi püsti aetud kui ma hästi mäletan oli vist 4 meetrine või isegi üle selle.dreamants kirjutas:Mu ühel tuttaval oleks kolm kärbest korraga: ettejääv mets maha müüa, seega kohe ka maa ülespanekuks olemas ja pakk raha ka seadmete ostmiseks.

Pärnus Pardi tänaval oli küll miski jurakas üleval, oli vist R.K. omanikuks . Pole teda aga juba neli-viis aastat kuskil kohanud, ei tea kas on alles.
