For RHCP and LHCP you would need an own LNB, possibly mounted into a single box. If the frequency difference between the lowest channel and highest channel of difference is larger than the IF passband, you will need separate front ends to cover the lower as well as higher end of the satellite band in both polarizations. If multiple satellites are needed, then more LNBs are needed. If C-band support is needed, add some more LNBs, if you want to select any channel at the receiver. > >>He'll need three circuits with power supplies at each end.

Is this building in the middle of a 100 m redwood forest or is at some high latitude e.g. in Alaska ? Installing a 30 m tower to the North of the building and installing the dishes on it, should give a clear field of view on most cases. If there is problems of snow accumulating into the dish, try an offset mount dish.

Somebody in alt.satellite.tv.europe reported that a simple plastic garbage bag over the dish works wonders to keep snow away, I think it was this thread: http://groups.google.com/group/alt.satellite.tv.europe/browse_thread/thread/2ded1da60b86c240/d39c8be4e552b8e8?lnk=gst&q=snow#d39c8be4e552b8e8

Ok, but with HDMI you'd be back to the single channel solution and the problem with the teenage daughters wanting "their" channels as well. Then the wife wants to see a dancing show while hubby absolutely has to see the ballgame. Lots of fibers. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam. Use another domain or send PM.

It is an operating system add on that takes over the gui. It is made specifically for the home theater user. |
