Is the ARDCKM-E-13X a broadband antenna?

No. The ARDCKM-E-13X is a narrowband UHF dipole antenna with a typical 20 MHz bandwidth, optimized for stable, repeatable performance around the selected operating range.

Which professional uses is this antenna suitable for?

It is suitable for professional UHF sites such as base stations and repeaters, public safety and utility radio networks, paging, telemetry/SCADA links, and radiomonitoring or RF survey activities where omnidirectional coverage is required.

What polarization does the ARDCKM-E-13X support?

The antenna supports linear polarization and can be used in vertical or horizontal orientation depending on the installation requirement.

Does the antenna include lightning and ESD protection features?

Yes. All metal parts are D.C. grounded, helping to reduce electrostatic charge build-up and improve robustness in outdoor installations.

UHF ANTENNA
MOD. ARDCKM-E-13X

The ARDCKM-E-13X is a narrowband omnidirectional UHF dipole antenna engineered for professional deployments where stable 360-degree coverage and repeatable performance are required across a tuned operating range within 300–600 MHz. With a typical 20 MHz bandwidth, it is an effective choice for fixed sites and field installations that must maintain consistent results.

Typical applications include UHF base stations, repeaters, public safety / PMR, utilities and industrial radio links, as well as radiomonitoring, RF surveys and interference investigations where an omnidirectional receive pattern is preferred.

Designed for severe climatic conditions, the antenna uses a stainless-steel support and a radiant dipole element available in aluminium or stainless steel, combining mechanical robustness with reliable long-term RF behaviour. An optional radome can be adopted to protect the adapter area in demanding outdoor installations.

The structure is built for professional mounting and includes a clamp system suitable for typical mast diameters used in UHF sites. The antenna is D.C. grounded (all metal parts), supporting improved robustness against electrostatic charge build-up and helping protect connected radio equipment.

Antenna designed and manufactured in Italy.

Frequently asked questions about ARDCKM-E-13X

Quick answers for planning and selecting the ARDCKM-E-13X narrowband UHF dipole antenna in professional installations.

What does “narrowband 20 MHz” mean for this antenna?

It indicates a tuned operating behaviour with a typical 20 MHz bandwidth, ideal when you need optimized performance around the selected UHF range rather than wideband operation.

Which systems typically use the ARDCKM-E-13X?

Common uses include UHF base stations, repeaters, public safety/PMR, utilities and industrial radio links, plus radiomonitoring and RF survey setups.

Can it be installed in vertical or horizontal polarization?

Yes. The antenna supports linear polarization and can be installed as V or H depending on the site requirement.

Does it help reduce electrostatic charge build-up?

Yes. The antenna is D.C. grounded (all metal parts), supporting improved robustness in outdoor environments and helping protect connected equipment.

Is a protective radome available?

Yes. A radome option is available to protect the adapter area, recommended for long-term operation in harsh weather and severe climatic conditions.

Which connector and power handling are provided?

The antenna is supplied with an N-f connector and supports up to 500 W maximum input power (typical).
