Sidelobe signals on 10'

[truckracer]

I added ku to my third big i used a dmx741. I know these combo lnbf's are not the best. C band is booming but I have sidelobe ku reception . I can bump the dish a few clicks and lose ku then pick it back up again. What is causing this? F/d? Or bad lnbf design?

Lobes will always be present in every antenna assembly. Dish design or assembly can increase the strength of side lobes.

Thanks. I never noticed it on my other dishes. This is a different dish.
