Hey everyone, I'm new to scanning. Most of the listening I do is to police and ems radio. I recently bought an external antenna (a UHF Directional and VHF Omni) which will go up on a mast connected to my chimney. I'm all set up to install it, but I don't know which way to point it. It's a silly question. I live close to downtown Houston (about 10 miles away); should I start by aiming it at downtown, or vice versa? Thanks for any feedback.
