I have been using a Diamond discone for almost 2 years now. Basically satisfied. It performs VERY well on vhf and uhf, but as we all know getting up into 800mhz it doesnt perform well. Currently it is connected to my BCT15X which is scanning all conventional (with exception of 1 small LTR system) police, rescue, fire, security, casino, maintenance etc......I am thinking about replacing the discone with something better for the bands I listen to on this radio. Ideally an antenna that will go from 30mhz up to UHF (512mhz). I am using a BCD996P2 for monitoring all local P25/800mhz which is working out very good using an 800mhz mag mount antenna on small ground plane on my roof right outside my window. I am on 2nd floor. The discone is very good for what I use it for but I may be able, with a BETTER antenna to pull in those weaker signals that the discone barely hears. I live in central Rhode Island. I can hear the fire departments over in eastern (Windham county) Connecticut with discone....a little weak from here but still usable. And I can hear very well into southeastern Mass. So does anybody know of an antenna that will be more suited for 30-500 mhz??? Years ago when I was an active amateur radio guy I used a dual band vertical for my scanner which worked very well, but at the time I lived on a decent hill with good elevation. Plus ham radio antennas are optimized for just those ham bands. It's too bad the Uniden rigs dont have multiple antenna jacks! One antenna I have my eye on is the "OMNI-X" from DPD Productions. Even though its a wider band antenna than I want I am wondering if it is better than the discone?
