Hey guys. I was able to purchase a Realistic PRO-2021 on eBay at a decent price. Any suggestions as to
a good "back of the set" replacement antenna? I think this scanner might be circa 1986,but not quite sure.
Any help is appreciated!
Most any rod or whip or rubbber duck antenna with a bnc connector (Diamond brand is well regarded among posters) placed on a right angle bnc connector will work. If all monitored frequencies are within one band then a band specific antenna may get you better results especially if the transmitters are low power or some distance away.
There are numerous threads here relating to the best antenna for a specific use, area, distance, etc.
