j'hesite je ne sais pas quoi prendre car j'ai un petit balcon

prendre 1 metre , 1m10 ou 1m20 ( c'est trop grand )


vous en pensez quoi ?

je suis sur marseille

tu ne peux pas mettre ton mat sur le mur de ton balcon, un peu en hauteur? si oui,n'hésite pas: la 1m20 , sinon si tu ne peux vraiment pas et que ton balcon est assez large pour accueillir une parabole de 90 cm(à marseille tu auras pas mal de fréquences ) alors fonce et prend une 90 cm(chez les sites marchands c'est noté 1m00 donc prend cette taille sur leur site car en vérité çà fait 90 cm et quelques)

Hi! 7*W is my favorite satellite, not for watching TV but to test antennas and different LNBs. There are my results from Brussels. 1,2m antenna (Fibo-120) installed on balcony. IBU LNB. Signals measured by DM8000. Automatically scanned 56 frequencies and found 915 services.

Merci RimaNTSS pour les tests depuis la Belgique avec une parabole de 120cm

Cela permettra de comparer la réception pour les personnes plus au sud qui n'arrive pas a recevoir certaine fréquence

Merci beaucoup oui ca donne de l'espoir car avec une 120 a bruxelles tu reussi a capter beaucoup de chaines !

Alors moi ici a Marseille avec une 100 ou une 110 ( voir 90 cm ) ca devrait passer largement!

J'espere !!

Attention
j'ai l'impression que cela vous a un peu échappé; c'est une 120cm Fibo avec double réflecteur, donc au moins équivalent à une 130 cm ( voir 1.40)

stephan94

C'est vrai stephan94 j'avais pas percuté sur la Fibo

Those are my results from Latvia, near Riga. 1,8m plastic Prodelin with sub-reflector from Gregory-type dish, measured by DM8000. Scanned about 200 services.

Add: LNB- Inverto Black Ultra. I've found it best performer nowadays.

Nilesat at Riga ? Nice reception !

And antenna's picture is here

that's a Fibo-Støp sub-reflector, probably not designed for that main reflector! Nice antenna!

I know it, but that was my main project of summer to attach Fibo-sub to 1.8m Prodelin and make it work better. And it worked.

how many dB have you increase your reception with the sub reflector?

mattmatt73 a écrit :how many dB have you increase your reception with the sub reflector?

I've calculated in %. Pointed antenna to Eutelsat 28A @ 28,5*E and recorded all levels on all 58 transponders with Inverto Black Ultra. Afterwards adopted same LNB to Fibo feedhorn and installed Fibo SUB to record signal levels again. In first case got average level 81,90% but with SUB average was 88,07%. So, average difference is about 6%.

What the hell did i just cought?!
Just scanned for fun full range at 8(not 7)W i got 12206 V 27499! It looks like it is from Nilesat 102 at 7.0°W.
How is that possible?
I live in Nord (see my ip if you wonder where), dish size is 1.2m and inverto black ultra lnb.




Update:
I moved my dish to 7W and got 5 tp
