Antennas

Perfecting Signal Capture

Antennas play a critical role in ensuring that your spectrum analyzer accurately captures both high and low-power signals. Our selection includes highly directional antennas for pinpointing sources with precision, as well as omnidirectional options for capturing a broader range of frequencies. With the right antenna, your spectrum analyzer becomes an even more powerful tool for detecting, measuring and analysing RF emissions across a wide spectrum.

Core Antenna Features

Wide frequency coverage — antennas designed to cover 30 MHz to 18 GHz for maximum versatility.
Directional models — highly focused beams for pinpointing sources with high accuracy.
Omnidirectional models — ideal for broad coverage, ideal for signal surveys in varied environments.
Rugged construction — built to withstand tough field conditions, providing reliability in challenging environments.
Compatible with multiple spectrum analyzers — designed for use with a wide range of spectrum analyzers for flexibility in operations.

Choosing the Right Antenna for Your Application

Your choice of antenna should depend on the task at hand. If you need to locate a source precisely, a directional antenna is ideal for narrowing down the location of signals. For general surveys or when you need to monitor a broad area, an omnidirectional antenna will capture signals from all directions. Frequency range and signal strength are also key factors—ensure you select an antenna that matches the bandwidth your spectrum analyzer can measure.

Representative Use Cases

TSCM operations — pinpoint and locate hidden bugs by using high-gain directional antennas.
Radio interference detection — use omnidirectional antennas to monitor broad-spectrum interference across communication channels.
Broadcast analysis — evaluate signal strength and coverage for TV, FM, or wireless broadcast frequencies.
Drone detection — use high-precision directional antennas to track and disable drone communications.
Telecom network testing — verify signal strength and quality across network cells with omnidirectional antennas.

Frequently Asked Questions

How do I know which antenna is best for my needs?
The best antenna depends on the specific task—whether you need to cover a wide area or pinpoint a specific source. Directional antennas offer precision, while omnidirectional models provide broader coverage.

Can I use any antenna with my spectrum analyzer?
Antennas are designed for specific frequencies and spectrum analyzer models. Always ensure that the antenna's frequency range matches the capabilities of your analyzer for optimal performance.

What is the typical range for these antennas?
Range depends on the antenna type, the signal power, and environmental conditions. Directional antennas provide precise coverage with higher gain, while omnidirectional antennas capture signals from all directions within a given range.

Are these antennas portable?
Yes. Many of the antennas are designed to be lightweight and easy to carry, suitable for fieldwork and portable spectrum analysis setups.
