Do you need an aftermarket antenna for your scanner? Will changing your antenna help or impair your scanner’s performance? What You Need To Know Stock antennas included with your scanner can cover large frequencies. Antennas with wide coverage will sacrifice performance. Antennas with too narrow coverage can also impair your reception. You don't want to have an 800 MHz antenna on your scanner when you're trying to also listen to VHF. However, if you have an 800MHz antenna and need to monitor 800MHz, then you may find a big improvement in reception. When we look at aftermarket antennas, we need to check what type of connector do we have on top of our scanner. Today’s scanners use BNC or some style of SMA. You need an antenna to match or buy adapters to make your new antenna match your scanner’s antenna jack. After market antennas can have gain, which can certainly help us pull in weaker signals. There may be times where you want to cause an intentional degradation of reception If you have issues with P25 simulcast, maybe you want to knock out distant transmitters and detuning your antenna might actually help you receive better. If you are receiving well enough using the stock antenna, will swapping the antenna out actually improve anything? You can’t receive 120% of a signal.   ==================================== ?
