I have tried several different antennas with the iscan with a variety of results. The stock antenna works but does not show what this little scanner can do. I have used the Diamond RH77CA and the Austin Condor, finding a nice boost in the overall performance of the scanner. The scanner liked my old RS rubber duckie that they used to sell that is larger than the normal stock GRE and RS scanners. The best match seems to be the 800 MHz BNC antenna. With it I get excellent reception in the 800MHz range, but also excellent reception in the air band frequencies. I live near our airport and get a wide range of ground and air communications. This little antenna does every bit as well as the Diamond and Austin antennas in receiving these signals. I plan to try my old RS center-loaded telescoping whip antenna to see if there are any improvements to be found in signal strength.
In the meantime, I will use the 800 MHz antenna for general reception. I have also found that Rayovac Hybrid batteries work well in this scanner. I get ten to eleven hours of use with the advantage of their ability to hold charge much longer than most other batteries. Right now they are on sale for $7.99 at Target for a package of four AA's or for two AA's in a charger.
