Broadband Omni disc antenna 300 MHz – 8 GHz, Linear, N-type

A broadband omnidirectional disc antenna covering 300 MHz to 8 GHz in a single unit — from VHF and UHF up to microwave. One antenna replaces a set of narrowband ones and the swapping between them mid-task.

The circular pattern gives even 360° coverage in the horizontal plane, so the antenna receives from any direction without being aimed. Linear polarisation is compatible with most standard transmitters and receivers.

Where it is used

• Spectrum monitoring and signal intelligence
• Laboratory measurement and equipment testing
• Wideband work with SDR receivers
• Integration into wireless and measurement systems

Construction and connection

The disc construction keeps the radiation characteristics stable across the whole band, without dips in particular segments. At 330 × 330 × 350 mm and 1 kg it can be installed permanently or used as part of a measurement setup.

It connects through an N-type Female connector at 50 Ω — the standard for measurement equipment and high-power paths. The 500 W input rating means it can be used for transmission as well as reception.
