ETRAB1550

Antennas RF Overview

The TE Connectivity ETRAB1550 is a low-profile VHF Phantom Elite whip antenna designed for mobile applications. It operates within the 155-160 MHz frequency band, providing unity gain (0 dB) performance. The unit features an NMO mobile mount base and measures approximately 2.38 inches in height. It utilizes a black stealth design to minimize visibility while maintaining signal integrity through patented true field diversity technology.

Antennas RF Feature Summary

• Patented true field diversity technology for improved signal reception compared to conventional whips
• Low-profile stealth design with black finish for reduced visual profile
• Unity gain radiation characteristics optimized for VHF mobile communications

Antennas RF Applications

• VHF mobile radio installations requiring low visibility
• Public safety vehicle communications systems
• Commercial fleet communication upgrades

Antennas RF Procurement Notes

Verify that the specific application requires an NMO mobile mount base configuration. Confirm that the operating frequency aligns strictly with the 155-160 MHz range. Ensure that separate mounting hardware and cabling are sourced as they are not included with the antenna unit. Check for RoHS compliance requirements if applicable to the project specifications.

Antennas RF Selection Notes

Select this model when low physical profile and stealth aesthetics are critical for vehicle integration. The NMO mount interface dictates compatibility with standard mobile vehicle roof fixtures. Consider the unity gain specification against higher gain alternatives if line-of-sight conditions are obstructed. Verify that the VHF band requirement matches the operational spectrum needs of the intended radio equipment.

Antennas RF Part Context

This component belongs to the Phantom Elite series, which emphasizes low visibility and advanced diversity performance. It is distinct from the ETRAB4503, which targets UHF frequencies with different gain and dimensional specifications. The ETRAB1550 specifically addresses VHF mobile needs where aesthetic concealment and compact form factors are prioritized over maximum range extension.

Antennas RF Replacement Considerations

Direct substitutes within the same Phantom Elite family include models with varying frequency bands but identical NMO mounting and low-profile designs. Cross-compatibility depends on matching the required VHF frequency range and mount type. Higher gain variants may offer performance differences but will alter the physical or electrical profile.
