Radio Shack Pro 63 Sensitivity.

[Pioneerman]

Hi there.. I've been doing some experimenting with my scanner last couple of nights and I have a question regarding sensitivity.

Happened to find a relatively small antenna for the scanner.. I'm pretty sure it's a CB antenna with a loading coil. Bought a BNC adapter. hooked it up and it seemed to have pulled in a couple of extra frequencies the OEM stubby wouldn't.

There are hot box detectors ( Railroad) not far from the train station, I know this because I heard them on somebody's ham radio transciever.

When I am looking at new scanners, how do I know if the scanner in question has decent sensitivity to pick up signals compared to a scanner that has crappy sensitivity?

Thanks!

They are usually very low power & short range, like fast food drive up windows., most scanners have about the same sensitiviy. as far as antennnas look for one in VHF range with a bit higher gain
