i just recently purchased a uniden bc246t scanner and will use it for both in my house and in my truck. now the question(s) i have is 1.) do i need a mobile antenna to use for in use in my truck and if so what antenna should i get. 2.) is the rubber antenna that it comes with good for mobile situations? i am new to the whole scanner business being in a vehicle. my dad has had a radio shack scanner for a few years that is awesome but only uses it for in the house.
