UrsaNav® UN-007 E-Field Antenna

Vertical E-Field Antenna for eLoran and LF Signal Reception

The UN-007 Antenna is a vertical E-field antenna engineered for use with Loran-C, Enhanced Loran (eLoran), and other Low Frequency (LF) signal systems. Designed to respond to the electric field component of LF transmissions, the UN-007 is ideal for time and frequency recovery in land-mobile, maritime, and portable applications.

This antenna is optimized for integration with UrsaNav’s eLoran receiver modules, including the UN-151, and supports high signal-to-noise performance in compact or embedded systems. Its lightweight, high-impedance design makes it well-suited for field deployment where a ground plane is available.

UN-007 Key Features

  • Vertical E-field antenna optimized for Loran-C, eLoran, and other LF signals

  • Compact form factor ideal for land-mobile, maritime, and handheld systems

  • High impedance with excellent signal-to-noise ratio for timing and navigation use

UN-007 Applications

The UN-007 offers strong LF signal reception in environments where space and power constraints are critical. It is especially effective in surface-based applications where precision timing is needed, and its E-field design supports compatibility with a wide range of LF receivers.

Compared to H-field antennas, E-field antennas like the UN-007 are more sensitive to precipitation static (P-static) and require a ground plane, but they offer good SNR and compact size—making them ideal for portable and vehicle-mounted systems.

Some applications include:

  • eLoran-based maritime timing and navigation

  • Land-mobile receiver installations

  • Portable or handheld time synchronization systems

  • LF backup signal reception for GNSS-resilient platforms

  • Industrial or research applications requiring compact E-field antennas

Why Choose the UN-007?

The UN-007 provides reliable electric field reception where performance, size, and integration flexibility matter. It’s a smart choice for:

  • Systems prioritizing accurate time and frequency recovery

  • Maritime and vehicular applications with stable mounting platforms

  • Compact deployments where H-field advantages are not required

  • Seamless integration with UrsaNav’s eLoran receiver modules
