Is the ARYCKM-E-37X a broadband or a narrowband UHF antenna?

The ARYCKM-E-37X is a narrowband UHF directional Yagi antenna. It is tuned within the 300-600 MHz range with a typical 25 MHz operating window.

Which polarization does the ARYCKM-E-37X support?

The antenna supports vertical and horizontal polarization (V/H), enabling flexible installation according to network design.

Is a protective radome available for this antenna?

Yes. A protective radome can be added on request to shield the adapter area in harsh outdoor installations.

What are typical professional uses for a narrowband UHF Yagi antenna?

Narrowband UHF Yagi antennas are commonly used for professional radio links and infrastructures such as PMR/LMR networks, public safety systems, utilities, SCADA/telemetry and RF survey activities where controlled directional coverage is required.

Does the ARYCKM-E-37X include lightning or DC grounding features?

All metal parts are D.C. grounded, providing an effective grounding path and helping protect connected equipment in outdoor sites.
