ARBF.XZ Handheld Directional Measurement Antenna for Radiomonitoring (2.4 / 3.6 / 5.8 GHz) - Protel Antennas - Professional Antennas for Telecomunications

ARBF.XZ Handheld Directional Measurement Antenna for radiomonitoring and interference hunting, available in 2400–2700 MHz, 3600–3800 MHz and 5100–5850 MHz versions (up to 20 dBi) with narrow beamwidth for fast RF direction finding.

The ARBF.XZ series is a handheld directional measurement antenna engineered for radiomonitoring, RF direction finding and interference hunting. Its compact architecture with single-element design and HAND HELD mounting is optimized for mobile field surveys and rapid checks around fixed monitoring stations, when a clean and selective reception angle is required.

The product family is offered in three band-specific versions to match the most common monitoring targets in different countries and frequency plans: ARBFAXZ (2400–2700 MHz), ARBFBXZ (3600–3800 MHz) and ARBFCXZ (5100–5850 MHz). These ranges are widely used for broadband wireless ecosystems and WLAN/Wi-Fi related checks (where applicable), as well as professional investigations in crowded RF environments.

Thanks to its high gain and narrow irradiation pattern, the ARBF.XZ improves selectivity and speeds up source localization: up to 16 dBi (2400–2700 MHz), 18 dBi (3600–3800 MHz) and 20 dBi (5100–5850 MHz), with beamwidth values down to 15°/14° at 5500 MHz. The antenna provides 50 Ω nominal impedance, N female connector and D.C. grounding of all metal parts for effective lightning protection practices during field operation.

For practical deployment, the dedicated accessories listed in the datasheet complete the kit: ARBFHH hand held clamp for stable pointing and BAGARBF transport bag for safe and quick transport, supporting repeatable measurements and professional documentation workflows.

Antenna designed and manufactured in Italy.

Frequently asked questions about ARBF.XZ handheld directional measurement antennas

Practical answers for radiomonitoring, RF direction finding and interference hunting applications.

Which ARBF.XZ version should I choose?

Select the band matching your monitoring target: ARBFAXZ (2400-2700 MHz), ARBFBXZ (3600-3800 MHz) or ARBFCXZ (5100-5850 MHz). Choosing the correct band improves selectivity and reduces unwanted pickup outside your investigation range.

Why is a narrow beamwidth important for interference hunting?

A narrow pattern helps isolate the direction of arrival and limits reception from off-axis sources, making it easier to locate emitters in dense RF environments.

Can I use the ARBF.XZ for both mobile missions and fixed monitoring checks?

Yes. The HAND HELD mounting concept supports mobile surveys, while the directional performance is also useful for controlled checks around fixed monitoring sites.

What polarization is supported?

The ARBF.XZ supports V/H polarization, allowing flexible use depending on the monitored system and the measurement setup.

Which accessories are available for field use?

The datasheet lists a dedicated transport bag (BAGARBF) and a hand held clamp (ARBFHH) to speed up deployment and ensure stable pointing.
