C-band lnb on Ku-band dish mods

Post by T95KPRO »

Someone try this? I order this kit to make a upgrade to get C-band channels on my Ku Dish. Any Sugestion?

C band Ku band combo LNB's are very fussy about alignment. They must point at the center of the dish.
You can loose some Ku signal with them.

So how did this experiment work for you? What was the size of the dish? It's been awhile since you posted this, and I was curious if it was good or bad.

Take care,

C band needs a lot more signal area, so you would need a 1.8m or bigger.
Some signal that are very strong will come through.
The issue is that with an off set dish the signal that reflects off the top of the dish arrives much latter than the signal from the shorter line off the bottom of the dish.
This degrades the signal and is why C band dishes are mostly prime focus.

No funciona la señal que te da es demasiado baja,para banda C lo mejor es usar un plato circular prime focus con su lnb al centro

With the new repositioning to come in the next years to alleviate 5G bullsh1t/mess, it could be easier to use this mod. As for now, its useless IMHO for north-America. A waste of time.

See hxxps://vvvvvv.tvrosat.com for more info, they're great on C-band news.

It{s not reliable, I tried to do this with an 1M x1.1M dish with my GTMedia V7S pointing to 117w and I just see 1 channel, so I will try to get a bigger dish (1.8m offset). Sometimes you can find free C band Dish antenas on Craiglist for free o close to nothing, sadly I'm in Mexico and here most people uses big C band Dishes to make garden kiosks :(

Por experiencia te dire que las antenas offset no sirven para banda c,tambien estoy en mexico y si se consiguen bastantes antenas de banda c (primefocus)de 3 metros y aun mas grandes muy baratas y en ocasiones hasta te las regalan si haces el trabajo de bajarlas,hay bastantes en las azoteas y ya no las usan solo es cuestion de tocar puertas y preguntar,saludos

El problema que yo tengo es que en la azotea del departamento no me dejan poner algo grande :( por eso busco algo chico como una offsett para aprovechar un espacio que hay. Si hay muchas antenas grandes sin uso, pero algunas gentes se pasan con el precio, una vez uno queria 5mil pesops por una de 2m XD .. y en muchos casos salian con que las van a usar algun dia o que van a usarlas para ponerlas de palapa en los ranchos :( .. asi es la gente aqui en jalisco.

I had bad experienced with this before on a 60cm offset dish. C+ku band with scalar works better on 120cm dish but tracking is another story.
