Halo Friends,

So Saturday my Sat buddy and me didn’t have much to do, so I had this crazy idea.
Why not take a C-band lnb. Cut out the back of it, and ad on a KU band one?
So that what we did. This is my first project with butchering a LNB. Must say it felt a bit awkward bringing a drill and porting bits to a LNB.EEEEEEK!!!
The result? Well, we got quite a few extra channels on Pas7/10!!Not spectacular ,as the KU band LNB is not a very good one, but it works none the less!

Here are some pics of the conversion

I remember seeing something similar to this somewhere before, I think they just used a regular 40mm clamp LNB on the back... :)

Great idea though, and cheaper than buying a combined Ku & C band LNBf unit... :D

Halo Friens,

Thanks for the nice comments.Yip,i will definately be putting on a better Quality Ku LNB later on.I didnt want to take the nice Ku one off the 1m dish.It would mean no european channels.hehe

hi there,good idea this:)
you,can also use simultaly,make a hole 3-4 cm,near,the cband lnb,in the feedhorn plate,and put,the kubnad lnb there,or buy,one of the c/kuband combifeeds ,have one here,but kuband performance,is not good,also,for kuband,signal is better,when you go more,inside the antenna , 1-2 cm,put Alu behind your dish,must be made very exactly,in cband no difrents,but,you can optimeized,the kuband signal then!
