Can I put my KU band LNB on my 10ft dish?

[rjc3895]

I currently have an 80cm dish with a universal KU band lnb. I'm just about ready to install my 10 foot dish for C-band. I have an extra universal KU band lnb. Can I attach this to the C-band feed horn and pick up KU band signals from my BUD? My dish meets the requirements for KU band (a pencil cannot pass through the holes).

Several people here have done it.

This looks interesting for a C/Ku solution.

A regular KU dish KU LNBF will not work on a large dish like a ten footer, do not mislead a C/KU LNBF to a KU dish LNBF. On the mesh dish, focal point play a major part of satellite reception. A KU dish focal point is under 22 inches and this is far less distant then the mesh dish can accepted.

SKS,

I didn't mean to confuse the two. Many people here have done just that (added offset Ku LNBF) and I agree with you that it isn't the best solution.

Here are a couple threads where people discussed cutting the scaler ring to add an offset LNBF:

Of course the better way to do C/Ku is to go with a C/KU feedhorn, or a C/Ku combined LNBF. I went for the C/Ku feedhorn.

ku lnbf on prime focus

I put an offset ku lnbf on my 7.5' foot prime focus dish. I know it is not really designed for a prime focus dish but it does work great. I drilled a hole in the back of my c-band lnbf and used liquid steel putty to adhere the ku lnbf's feedhorn into place. I made sure the horizontal and vertical probes were aligned between the lnbfs so i would have accurate skew adjustments for both c and ku band.

It works well, i am sure its a compromise since i am not an engineer but it works well for me, strong signal quality percentages on all sats c and ku bands.
