Replacing the Antenna

The antenna that comes with the USB dongle is small. You can easily get much better signal reception by replacing it with a better antenna, or one better matched to the frequency range you want to listen to. Many of the USB dongles use a PAL connector. You can purchase IEC PAL male to BNC or SMA adapters for less than $4 on eBay. Once you have an adapter, you can easily connect another antenna.

You can purchase telescopic CB or scanner radios with BNC connectors for under $10 online.

Making your own antenna is fairly easy, too. See the projects page for instructions on making some antennas.
