[QUOTE="archive10, post: 896736"] Not sure I'll be in the summer cottage then. (It is after all not summer anymore?!?) :D I am happy to say that the LNB does indeed point to the very center of the CM120. Nothing bent here. Some time ago, I had one particular Telesystem P57, IIRC, which was oval. But in contrast to similar looking Sky Minidishes, no special LNBs with oval feedhorns were required / supplied. In fact, when using the (non-adjustable) integrated plastic LNB arm+holder, the LNB was clearly pointing to somewhere two thirds up the reflector. Loosening the LNB, and pointing towards the center (downward tilt) gave another 1.5dB of signal strength, which is not insubtantial when you are looking at a dish with a gain of 34 dB! After much head-scratching, I checked the Telesystems web-page, and shure enough, the P57 has a bigger brother with a *round* reflector (well, as in circle projected onto parabolic surface), using the same LNB arm+holder. On this dish, the LNB *did* point to the center of the reflector. To create the oval version, they simply designed a smaller reflector, but kept everything else... [/QUOTE]
