Police Scanner Accessories Guide

The right accessories can dramatically improve your scanner experience. From programming cables that save hours of setup time to antennas that extend your range, here's what you need to get the most from your scanner.

Essential Accessories by Category

Programming Cables

Programming your scanner manually via the keypad is tedious—especially with modern scanners that can store thousands of frequencies. A USB programming cable lets you use software to configure your scanner in minutes instead of hours.

EZSync USB Programming Cable

$15–$20

Third-party USB-1 compatible cable. Works with all Windows versions including Windows 10/11. Genuine serial chipset for reliable connection.

Compatible with: Same as USB-1—BC246T, BC346XT, BCD396T, BCD996T, and more

Washinglee USB-1 Cable

$12–$18

Budget option with built-in FTDI chip. Supports Windows, Mac, and Linux. Good reviews for reliability.

Note: SDS100/SDS200 Owners

The Uniden SDS100 and SDS200 use a standard Micro-USB cable for programming. You likely already have one from a phone or tablet. No special cable needed—just use Uniden's free Sentinel software.

Antennas

Your antenna is the most important factor in reception quality after the scanner itself. Upgrading from the stock "rubber duck" antenna can dramatically improve what you hear.

Nagoya NA-771 Antenna

$15–$25

Popular upgrade for handheld scanners. At 15.6 inches, it provides significantly better reception than stock antennas. Available in SMA-Male and SMA-Female versions.

Best for: Handheld scanner upgrade, portable use

Power & Batteries

Power Options for Scanners

Home Use

  • Use the included AC adapter
  • Consider a surge protector
  • UPS for continuous monitoring

Portable Use

  • Rechargeable NiMH AAs (Eneloop)
  • OEM battery packs when available
  • Carry spare batteries

Vehicle Use

  • 12V DC adapter cable
  • Cigarette lighter adapter
  • Hardwire kit for permanent install

Battery Warning

Never use non-rechargeable batteries in charger-equipped scanners. Some scanners have built-in charging circuits that expect rechargeable batteries. Using alkaline batteries in these chargers can cause leakage, overheating, or damage.

Cases & Mounting

Mounting Options

  • Belt clips: Most handhelds include one—check for aftermarket options if yours breaks
  • Carrying cases: Protect your scanner and allow use while holstered
  • Vehicle mounts: Dashboard or console mounts for mobile scanning
  • Desk stands: Angle your scanner for better visibility at home

DIY Tip

Many scanner owners use generic phone mounts or tablet stands for their scanners. As long as the size is right, you don't need expensive scanner-specific accessories.

Software (Free)

Don't forget about software—most is free:

  • Uniden Sentinel — Free programming software for SDS100/SDS200. Download from Uniden's website.
  • FreeSCAN — Free software for BCD396XT, BCD996XT, and similar models.
  • RadioReference Database — Import frequency data directly to your scanner (membership required for some features).
  • Proscan — Popular third-party software for advanced programming.

The Encryption Reality

No Accessory Beats Encryption

While accessories can improve your scanning experience, remember: no antenna, cable, or accessory can decode encrypted police communications.

Before investing in accessories, verify that your area isn't encrypted. If it is, consider advocating for police radio transparency instead.

Frequently Asked Questions

Do I need a programming cable for my scanner?

Not required, but highly recommended. Programming cables let you use software to configure your scanner much faster than manual keypad entry. For scanners with hundreds of frequencies, it saves hours of work.

What programming software works with Uniden scanners?

Uniden's Sentinel software (free) works with SDS100/SDS200. For older models like the BCD436HP, use FreeSCAN (free) or ARC software (paid). RadioReference also offers frequency import tools.

Is an external antenna worth it for a handheld scanner?

Yes, if you're using it at home. Connecting to an outdoor discone antenna dramatically improves reception. Most handhelds have SMA or BNC connectors for external antennas.

What batteries work best for portable scanners?

Rechargeable NiMH AA batteries (like Eneloop) are most economical for scanners that use AAs. For scanners with proprietary battery packs, stick with OEM replacements to avoid damage.

Can I use car power for my handheld scanner?

Yes, with a 12V DC adapter cable. Many handhelds accept 12V input. Check your scanner's voltage requirements before connecting—some need specific adapters.
