I have a Uniden BC125at and was looking into getting an antenna for my car. I already found a good mount, but what about an antenna? I need frequency's from 155-460mhz..at minimum. I found this antenna, but its only 152-162mhz. I then found this antenna which is perfect, but have a few questions. The antenna says it has a maximum power of 200watts while the other antenna isn't powered. Note that I will NOT be transmitting anything, just receiving. Will this antenna work for my scanner even though it requires power..or is the maximum power just for transmitting. Also is the powered antenna better than the other non powered one? Thanks!
