Question: How do I find an antenna for this scanner?
Document: I really like this scanner. It certainly does the job. Radio Shack is a good name in the industry for electronics for this type of radio.
The RadioShack Pro 405 200 Channel Desktop Radio Scanner did everything I wanted it to do plus it has a radio. Can't beat the price.
Received scanner the NEXT DAY!! I will use this to assess winter road conditions before I decide to leave for work or not. Great product.
Same one we already have and couldn't find anywhere except on Amazon. He was very excited, now he stays awake at night listening. Very easy to program too.
The machine is all that I expected
this desktop scanner is the best one i ever owe  it come good where i lived  thank you
This is Radio Shacks Desktop version of the Pro -404 scanner. It sports the same features as the Pro 404 (200 Channels, Preprogrammed buttons ) but with a plus, FM radio
Love this scanner. Once programed correctly it works well. Appreciate all the help that was given by Cell Locker, owner Frank and his technician, Jeremy for all their help to get the scanner programmed correctly. They gave &#34;True customer service.&#34;  :)
Works ok. It uses a wall wart that puts out 9 volts. It would have be better if it were designed for 12 volts.FM broadcast reception is good. Police broadcast reception is good. You should check what frequencies your policedepartment uses because it does not receive 900 mhz band.
