An lnbf or should I stick with corotor?

[lonewolf454]

I am in process of reinstalling my c/ku band equipment and wonder if any of the lnbf available are as good as the old chapparel or calamp co rotor lnb's? I need it to be c and ku band dual feed. Not sure if there is such a beast but would save some cabling. I would rather run the belden cable for the rotor though than have more attenuation. Your thoughts?

Inverto c band or DMS internacional 13k lnb

I've had my issues over the years with corotor and that is why I am using lnbfs. Dual c/ku band lnbf always suffer on the ku side. I would suggest seperate lnbf with one of your feeds being placed on the side, there will be a seperation of about 7-8 degrees but no big deal. I also assume that your dish, if mesh, has the small holes or else ku band will be useless. My recommendation would be a 10'(3m) mesh dish dedicated to c band and a 4'(1.2m) CM dish for ku band.

The 10.5 footer is a RayDX, holes are small enough for reliable ku reception, Thanks for the rec's.

I would go co rotor but I agree with Costactc with another dish for Ku. I run a 10ft for c and a 5ft for ku

Instead of setting up additional antenna, it is possible to change LNBs. This VIDEO shows how it can be done on the offset dish, but, if needed, same mechanism can be made for prime-focus dish.
