IS the antenna amplified? If so is probably a 10db amplifier gain. That means anything the antenna hears, no matter how poorly, will be amplified 10db above what it was before it got to the antenna including noise. You may want to be careful if it is amplified especially if you are able to hear signals clearly without it. Where I live I cant use any amplifiers because I am within 200 yards of the county sherrifs office and they have both a repeater channel and a simplex channel they use and the station has such a high ERP that it blanks out adjacent frequencies and using an amplifier causes the scanner to be unusable when they are transmitting. For all intents and purposes the rabbit ears are only going to be unity gain at best unless it is a directional antenna and then it will exibit foward gain in the direction you ahve it pointed, usually at best only a few db
