UNIDEN SPM200 - AM/FM Band Splitter for VHF or 27MHz Antennas

Professional AM/FM band splitter enabling single antenna shared use between car stereo and UHF/VHF/CB radio, eliminates need for multiple antennas cluttering vehicle roof, splits antenna signal to both AM/FM receiver and communication radio simultaneously, compatible with VHF marine radios and 27MHz CB radios, reduces installation complexity and vehicle aesthetics impact, professional-grade signal isolation prevents interference between devices, compact inline design installs between antenna and equipment, maintains optimal signal quality for both AM/FM broadcast reception and two-way radio communication.

Product Overview

The UNIDEN SPM200 AM/FM Band Splitter provides elegant solution for vehicles requiring both entertainment and communication capabilities without multiple roof-mounted antennas. This professional-grade splitter enables single VHF or 27MHz antenna to serve both car stereo AM/FM reception and UHF/VHF/CB radio communication simultaneously, reducing installation complexity and improving vehicle aesthetics. The splitter uses frequency-selective filtering to direct AM/FM broadcast signals (540-1600kHz AM, 88-108MHz FM) to car stereo while passing communication frequencies (27MHz CB or VHF marine bands) to two-way radio without interference between systems. Ideal for 4WD vehicles, work trucks, marine vessels, caravans, or any application where roof space is limited or clean appearance is desired, the SPM200 delivers professional installation results with maintained signal quality for both entertainment and safety communication.

Important Notes:

Antenna Compatibility: Splitter works with VHF marine antennas or 27MHz CB antennas only. Not compatible with UHF CB antennas (476-477MHz) as these frequencies cannot be split for AM/FM use.

Single Antenna Required: This device enables one antenna to serve two purposes (AM/FM + communication radio). You must have appropriate VHF or 27MHz antenna installed - splitter does not work without compatible antenna.

Professional Installation Recommended: While DIY installation is possible, professional installation ensures optimal performance, correct connections, proper grounding, and interference-free operation between stereo and radio systems.

Key Features

Single Antenna Dual Function - Enables one VHF or 27MHz antenna to serve both car stereo AM/FM reception and two-way radio communication simultaneously, eliminating need for multiple antennas cluttering vehicle roof.

AM/FM Band Splitting - Frequency-selective filtering directs AM broadcast (540-1600kHz) and FM broadcast (88-108MHz) signals to car stereo while passing communication frequencies to radio without interference.

Compatible with VHF Marine Radios - Works with VHF marine radios (156-163MHz) commonly used in boats, allowing single antenna for both entertainment and marine communication when space is limited.

Compatible with 27MHz CB Radios - Functions with 27MHz CB radios (26.965-27.405MHz) popular in older communication systems, enabling shared antenna use with car stereo in vehicles or caravans.

Professional Signal Isolation - Engineered filtering prevents interference between AM/FM receiver and communication radio, maintaining clean audio and clear communication without crosstalk or noise.

Reduces Roof Clutter - Eliminates need for separate AM/FM and communication antennas, improving vehicle aesthetics and reducing wind noise, especially important for modern vehicles or professional fleet appearance.

Maintains Signal Quality - Properly designed impedance matching and low-loss construction preserve signal strength for both AM/FM reception and two-way radio performance without degradation.

Compact Inline Design - Small weatherproof housing installs inline between antenna and equipment, typically mounted under dashboard or in concealed location without requiring dashboard modifications.

Simplified Installation - Reduces installation complexity compared to dual-antenna systems, requiring only one roof penetration and one antenna mounting point with simplified cable routing.

Cost-Effective Solution - Eliminates expense of second antenna, mounting hardware, and additional roof penetration labor, while achieving professional dual-function results.

Ideal for Space-Limited Applications - Perfect for vehicles, caravans, or boats where roof space is limited, multiple antennas are impractical, or clean appearance is priority.

Professional Fleet Applications - Suitable for commercial fleets, emergency services, or government vehicles requiring communication capability with minimal visual impact for professional appearance.

Technical Specifications

Frequently Asked Questions

Q: Can I use this splitter with my UHF CB radio (476-477MHz)?

A: No, the SPM200 is NOT compatible with UHF CB radios operating on 476-477MHz frequencies. This splitter is designed specifically for 27MHz CB radios (older CB band) and VHF marine radios (156-163MHz) only. UHF CB frequencies cannot be split for AM/FM use with this device. If you need to share an antenna between AM/FM and UHF CB, you require a different specialized splitter designed for UHF frequencies.

Q: Will using a splitter reduce my radio performance or AM/FM reception quality?

A: A properly installed SPM200 maintains signal quality for both AM/FM and communication radio with minimal insertion loss. However, performance depends on quality antenna installation, correct connections, and proper grounding. You may experience slight signal reduction compared to dedicated separate antennas, but for most users the difference is negligible and the benefits of single-antenna installation outweigh minor performance trade-offs. Professional installation ensures optimal results.

Q: Do I need any additional cables or equipment to install this splitter?

A: You may need additional coaxial cables depending on your specific installation, as the splitter requires connections from antenna to splitter, splitter to stereo, and splitter to radio. Cables are not included with the SPM200. You'll also need appropriate antenna (VHF or 27MHz CB) if not already installed. We recommend consulting with professional installer to determine exact cable requirements for your vehicle configuration and ensure correct connectors and lengths.

Q: Can I install this myself or do I need a professional?

A: While experienced DIY installers can install the SPM200, professional installation is strongly recommended to ensure optimal performance, correct connections, proper grounding, and interference-free operation. Incorrect installation can result in poor AM/FM reception, reduced radio performance, electrical interference, or damage to equipment. Professional installers have experience with antenna systems, signal routing, and troubleshooting issues that may arise during installation.

Q: Will this work with my marine VHF radio on my boat?

A: Yes! The SPM200 is compatible with VHF marine radios (156-163MHz) and is commonly used in boats where space is limited and multiple antennas are impractical. The splitter allows single VHF antenna to serve both marine stereo AM/FM reception and VHF marine radio communication. This is particularly valuable on smaller vessels where mounting multiple antennas creates wind resistance, cluttered appearance, or installation difficulties. Ensure proper marine-grade installation with weather-resistant connections.
