Buying Guide for the Best External Antenna For Police Scanner
Choosing the right external antenna for your police scanner can significantly enhance your listening experience by improving signal reception and clarity. The right antenna will depend on several factors, including your location, the frequencies you want to monitor, and your specific needs. Understanding the key specifications will help you make an informed decision and ensure you get the best performance from your police scanner.Frequency RangeThe frequency range of an antenna indicates the range of frequencies it can effectively receive. This is important because police scanners operate on specific frequency bands, and you need an antenna that can cover those bands. Frequency ranges are usually given in MHz (megahertz). If you are monitoring a wide range of frequencies, look for a wideband antenna. If you are focused on a specific band, a narrowband antenna might offer better performance. Determine the frequencies used by your local police and emergency services and choose an antenna that covers those frequencies.
GainGain measures the antenna's ability to amplify signals and is usually expressed in dB (decibels). Higher gain antennas can pick up weaker signals from further away, which is useful if you are in a rural area or far from the source of the transmissions. However, high gain antennas can also pick up more noise and interference in urban areas. If you are in a city with strong signals, a lower gain antenna might be sufficient. Consider your location and the strength of the signals you want to receive when choosing the gain.
Antenna TypeThere are several types of antennas, including whip, dipole, and directional antennas. Whip antennas are simple and versatile, suitable for general use. Dipole antennas are good for fixed locations and can offer better performance for specific frequencies. Directional antennas focus on signals from a specific direction, which can be useful if you know where the transmissions are coming from. Think about where you will be using the antenna and whether you need a portable or fixed solution when choosing the type.
Mounting OptionsMounting options refer to how and where you can install the antenna. Common options include magnetic mounts, window mounts, and roof mounts. Magnetic mounts are easy to install and remove, making them ideal for temporary setups or vehicles. Window mounts are convenient for indoor use. Roof mounts provide the best performance by placing the antenna higher and away from obstructions. Consider where you will be using the antenna and choose a mounting option that suits your needs and installation preferences.
Cable Length and TypeThe cable length and type can affect signal quality and ease of installation. Longer cables allow more flexibility in antenna placement but can result in signal loss. Coaxial cables are commonly used for their good balance of flexibility and signal quality. Make sure the cable is long enough to reach from the antenna to your scanner without excessive slack. Also, check the connectors to ensure they are compatible with your scanner. Choose a cable that provides a good balance between length and signal quality for your setup.
