Thing is: With your signal levels, you should be receiving all the LOS easily as long as the antenna is aimed 'their way'. If not there's something amiss. Got to be fixed before adding another antenna to aim in another direction.
Have you tried replacing the transformer on the antenna? This is 'my bet' for being bad. I've had 'NEW' ones that were bad. 2nd bet: Coax from amp to antenna transformer.
Both are cheap, just replace 'em, in one trip.
