My son is a firefighter for MoCo ESD1. I live a stones throw from main station 91 or about an eighth of a mile from I45 on FM1097 west. I'm primarily interested in listening to fire/EMS in my area but I want to be able to pick up as many of the transmissions as possible. Anything out of my area would be a bonus. I know a little bit about how trunking works. I don't want to blow a lot of money on a trunked scanner if I'm not going to be able to pick up much more than an $80 Bearcat. I'm retired so I'd be using it at my desk. With that said I understand running an outdoor antenna would be ideal. I might be willing to pay more for a quality indoor antenna if it saves me the trouble of having to install an outdoor one...if that's even a thing. Long story short I'm looking for a radio that would give me the biggest return at the lowest cost. Thanks in advance.
