Description

The Telex APS-1 is a compact, high-performance broadband antenna combiner-splitter engineered to optimize RF signal paths across the 100 MHz to 900 MHz range. Designed for field technicians, installers, and operations teams, this small device delivers robust signal sharing and splitting without sacrificing quality. With its approximately 2x2 inch footprint, the APS-1 fits neatly into crowded rack spaces, tight vehicle installations, or portable setups where every inch counts. Its passive design means no external power is required, reducing complexity and heat generation while maintaining reliable performance in demanding environments. Whether you’re coordinating multiple antennas for a two-way radio network, aggregating signals for a scanner system, or enabling flexible antenna configurations in multi-band deployments, the APS-1 provides a dependable, low-loss solution that minimizes interference and protects signal integrity across the entire operating bandwidth.

  • Broad frequency coverage for multi-band setups: The APS-1 handles signals across 100 MHz to 900 MHz, making it ideal for shared-antenna configurations in two-way radio, mobile communications, VHF/UHF scanning, and other broadband applications. This wide band ensures compatibility with a variety of antennas and transceivers, reducing the need for multiple adapters or devices and simplifying your RF topology while preserving strong signal fidelity across the spectrum.
  • Ultra-compact, space-saving design: With a small footprint of approximately 2x2 inches, the APS-1 is perfect for tight installations, portable field kits, and compact enclosures. The compact size does not compromise performance, enabling you to deploy reliable antenna sharing in environments where space is at a premium, such as vehicle dashboards, equipment racks, or portable emergency response kits.
  • Low insertion loss for strong signal, every channel: The APS-1 delivers a typical insertion loss of about -3.5 dB, balancing compact form factor with high efficiency. This low loss helps preserve signal strength when combining or splitting RF paths, supporting clear reception and reliable transmission across the entire frequency band without introducing unnecessary degradation.
  • High isolation to reduce cross-talk and interference: Typical isolation of 26 dB helps prevent unwanted leakage between the combined or split channels. This is critical in multi-antenna configurations where adjacent signals can otherwise interfere with one another, ensuring cleaner reception, better differentiation between channels, and more stable system performance in complex RF environments.
  • Rugged TNC connectors for secure, quick connections: The APS-1 uses convenient TNC connectors that are widely compatible with common RF cabling and equipment. The connectors provide reliable, vibration-resistant mating and straightforward installation, enabling faster setup, easy maintenance, and durable operation in both laboratory and field conditions.

How to Install Telex APS-1 Broadband Antenna Combiner-Splitter

  • Power down all connected equipment before making any connections to avoid RF shock or damage. Ensure all devices share a common ground to minimize potential ground loops.
  • Inspect the APS-1 and mating cables for any damage or worn connectors. Replace any compromised cables to maintain optimal performance and prevent signal loss.
  • Identify your input and output pathways. If using as a combiner, connect multiple antenna feeds to the designated inputs; if used as a splitter, connect a single feed to the input path and route outputs to the respective receivers or antennas as designed.
  • Attach the TNC cables firmly to the APS-1’s connectors. Hand-tighten securely, then give a gentle turn with a wrench if required by your connector hardware, taking care not to overtighten and damage the connector threads.
  • Mount the device on a stable surface or in an appropriate enclosure. For outdoor installations, use weatherproof housing or sealing procedures recommended for your environment to protect the unit from moisture and dust.
  • Connect the remaining RF paths to your radios, scanners, or other equipment. Ensure correct labeling of inputs and outputs if your system includes multiple channels to avoid misrouting signals.
  • Power up the system and perform a basic RF check. Confirm that signals are present on the intended channels and verify that cross-talk remains within acceptable levels. If interference is detected, re-check cable routing and grounding, and consider adding shielding or reconfiguring the antenna plan.
  • Document the installation with a simple schematic or notes. Include antenna types, cable lengths, and connector types to simplify future maintenance or upgrades.
