Choosing the correct Car Scanner Aerial, also known as an antenna, significantly impacts your scanner’s performance. The ideal aerial depends on your listening preferences, budget, and required frequency coverage. This guide helps you understand the importance of a quality car scanner aerial and provides recommendations for selecting the right one.
Factors Influencing Car Scanner Aerial Choice
A single antenna rarely covers all frequencies. Understanding your specific needs is crucial for optimal performance. Consider these factors when choosing a car scanner aerial:
- Frequency Range: Determine the frequencies you want to monitor (VHF, UHF, 700/800MHz, VHF Low Band). Different antennas specialize in specific bands.
- Mounting Location: The mounting location on your vehicle (roof, trunk, etc.) affects antenna performance and choice.
- Budget: Quality antennas often come at a higher price, but their durability and performance outweigh the initial cost.
- Vehicle Type: The height and type of your vehicle can influence antenna selection. A taller vehicle might benefit from a different antenna than a smaller car.
NMO Mount Antennas: A Versatile Solution
For many users, multi-band NMO (New Motorola Mount) antennas provide a good balance of performance and versatility, especially if VHF Low Band coverage isn’t required. The NMO standard offers a wide array of antenna options, making it a popular choice for two-way radio and scanner users.
The Larsen NMO-150/450/758 is a reliable choice for mounting on taller vehicles. This antenna features a spring base and flexible whip, making it durable and suitable for environments with low-hanging obstacles. It effectively covers VHF, UHF, and the 700/800MHz bands. (Product Link)
For a budget-friendly option without the high flexibility, consider the Larsen NMO-150/450/800. This antenna offers similar frequency coverage to the NMO-150/450/758 but lacks the spring base. (Product Link)
Addressing VHF Low Band Requirements
If VHF Low Band reception is necessary, consider using a dedicated low-band whip antenna in conjunction with one of the aforementioned NMO antennas. A diplexer is required to combine the signals from both antennas into a single coaxial cable for your scanner.
Prioritizing Antenna Quality
The antenna is the most critical component of your radio setup. A high-quality antenna paired with a less expensive scanner will generally outperform an expensive scanner with a poor antenna. Invest in a durable, well-built antenna from reputable brands like Larsen, PCTel, Laird, or EM Wave. Avoid inexpensive, low-quality antennas, as they often result in poor reception and reliability.
Conclusion
Choosing the right car scanner aerial is paramount for optimal performance. Carefully consider your specific needs and invest in a quality antenna from a reputable manufacturer. Remember, a good antenna significantly enhances your scanner’s ability to receive signals clearly and reliably.
