My mother-in-law would like to share her neighbor's satellite dish antenna, but doesn't want to be restricted to watching the same program as her neighbor. Is it necessary to purchase another receiver (both of which would then be hooked up to the same LNA), or do these receivers tune a whole "bank" of channels, which are then selected using something low-cost, like a cable TV channel selector? Assuming a cooperative neighbor, how inexpensively can I accomplish what she wants? (She already knows that she's going to be limited to channels carried on the same satellite her neighbor is tuning, of course.) -- Jan Wolitzky, AT&T Bell Labs, Murray Hill, NJ; 201 582-2998; mhuxd!wolit (Affiliation given for identification purposes only)

Since most cheap satellite TV setups use a downconverter which is "tuned" by the receiver, you would probably end up needing two receiver/downconverter sets. You would also have to make sure you got enough power out of the LNA to feed both units, and you would be restricted to simultaneously watching channels not only on the same satellite, but on the same POLARIZATION as well (half the transponders are vertical, half are horizontal). To get around this, you'd need a dual-polarity feedhorn and another LNA as well. --Lauren--

What you can get is a block down converter/LNA which will enable more than one receiver to be hooked up. -- Anthony Albert ..!ucbvax!albert albert@ucbvax.ARPA
