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.
