Whats the difference.

between the what I call the feed horn and the antenna? It seems antennas are always being repaired. What goes wrong with them anyway?

The portion of the detector that people on here always call the "horn" is really the whole RF receiver portion of the detector, generally containg the oscillators, mixers, and IF stages. The actual "horn" consists only of the flared portion, which is the antenna. Nothing ever really goes wrong with the actual horn, it is the rest of the RF components where failures occur.

Generally a "feed horn" is a horn antenna used to "feed" something else, in many cases a satellite dish...
