After using my Handheld UBC 120 XLT scanner for a bit, it was obvious that I needed a better antenna to get more range. Some research on the net indicated the Diamond D130J was a good multipurpose antenna to purchase. It set me back around $160 to get one from the Eastern States as nowhere in Perth sold one that I could find. I also mounted the antenna on a three metre pole to the roof, with some quad shield cable running inside. Now I can hear everything I couldn't before :)
