[QUOTE="a33, post: 959111, member: 332642"] Well, if LNB surface is about 4 cm in front of LNB bracket, then fG would be about 28 cm and horizontal distance between LNBs would be about 3,7 cm. So LNBs 3,7 cm apart would be best. I believe that with LNBs (necks) till about 4,7 cm apart (maximum!!) you could probably have reception (both LNBs then 0,5 cm off), but I'm not sure about this tolerance. And it would mean worse reception quality, then. I guess the LNBs that you have have a diameter of about 6 cm? With these it would be impossible. I don't know what is the distance in these 3degree monoblocks you mentioned. Have you checked already? Or does anybody else on this forum know? Otherwise you need slim LNBs. The ALPS Rocketfeeds LNBs would probably do (heads of 4,2 cm). Or other slim LNBs (there are a few types). But then the problem remains, how to make a bracket for this distance. And of course, with slim LNBs you would need rain-protection (as they are more sensitive to rain in regard to signal quality). greetz, A33 [/QUOTE]
