High Gain Heavy Duty Omni Antenna Lineup

 

High-Gain Heavy-Duty Omni Antennas

You want antennas you can trust in harsh conditions.
You want consistent performance when your network has no room for error.
That’s what this lineup delivers.

These antennas are built for teams who manage public safety systems, utility networks, and large-scale industrial deployments. You get hardware designed to stay stable under stress, hold pattern integrity at higher gains, and keep connectivity alive when the environment works against you.

You also get complete transparency. Each model comes with documented test data, giving you full confidence in the numbers behind the performance.

What Makes These Antennas Stand Out

Strong RF performance

You gain stable radiation patterns even at higher dBd levels.
This matters when your network depends on predictable coverage and reliable reach.

Low PIM

You reduce distortion and improve throughput.
This helps you avoid dropped signals during peak activity.

High PIP

You protect your system from damage during high-power events.
Your signal stays clean, and your hardware stays safe.

Tough construction

You can run these antennas in wind speeds up to 240 km/h.
You can add top-mounted lightning protection when your site calls for it.

Broad compatibility

You cover LTE700, LTE800, LTE900, public safety bands, GSM900, and smart-metering networks.
You keep your deployment flexible without switching platforms.

Product Lineup

You’ll see that each model serves a slightly different purpose.
As you compare them, think about what your site needs most:
More gain?
A specific radiation pattern?
Null fill?
Directional control?

Use these questions to guide your choice.
