The Radio Shack 800mhz antenna is awesome antenna for 800 band with little loss in the other bands, for general scanning the Diamond RH77CA also called the Watson 881 Super Gainer on scannermaster is a great antenna, although its really long, its worth it if a long antenna isn't a problem. I went from about a 20mile radius to close to 50miles... While I know that may not be typical results, I can attest that both are really good antenna's...I have them both, and swap them out quite often depending on what I am doing...
