Factors to Consider When Choosing an Antenna

Before jumping into the list of the best antennas, let’s take a quick look at the key factors to consider when selecting the right antenna for your scanner:

  1. Frequency Coverage: Ensure that the antenna is optimized for the VHF (136-174 MHz) and UHF (400-512 MHz) bands, as well as any other specific bands you are interested in, such as airband (118-136 MHz) or public safety frequencies.
  2. Portability: If you plan to use the BC125AT on the go, a compact or flexible antenna will be more convenient than a large whip antenna.
  3. Connector Type: The BC125AT uses a BNC connector, so you’ll want to select an antenna that fits directly or with an appropriate adapter.
  4. Signal Gain: Antennas with higher gain will offer better performance over longer distances but may be more directional.
  5. Indoor vs. Outdoor Use: Depending on where you plan to use your scanner, you might opt for a portable antenna or a base station antenna for home use.

Conclusion: Which Antenna Should You Choose?

The best antenna for your Uniden BC125AT depends on your specific needs and how you plan to use the scanner:

  • Best for Aviation Enthusiasts: Diamond RH77CA for superior airband reception.
  • Best for VHF/UHF Scanning: Nagoya NA-771 for improved public service and emergency band performance.

  • Best for Portability: SRH805S for compact, everyday use.
  • Best All-Around Performance: Comet SMA-24 for broad frequency coverage and flexible use.

If you’re primarily using the scanner outdoors or in different environments, the Nagoya NA-771 or Diamond RH77CA will give you the best performance. However, if you need a compact, easy-to-carry solution, the SRH805S is ideal. For in-car use, the Tram 1185 provides excellent reception without compromising convenience.

Upgrading your antenna can make a significant difference in the performance of the BC125AT, allowing you to pick up more signals with better clarity.
