Features |

Frequency 1 - 8 GHz
|
Wideband Horn Antennas
These multi-Octave range wideband horns offer an unrivalled facility for
measurements, evaluation and electronic surveillance.
The band of 0.5 GHz to 18 GHz
can be covered with only 2 to 4 wideband horn antennas.

 |
Wideband Horn Features
- Connector - SMA or N type (others available, please contact
us for details)
- A full wideband horn antenna test report including gain
against frequency is provided with each horn
- Ideal for spectrum monitoring and surveillance, and EMC
applications
- Wideband horns are normally fitted with an integrated
coaxial to waveguide adaptor, but can also be supplied with just
a waveguide flange - including WRD ridged waveguide.
- Broadband Ridged Horns that are compatible with WRD ridged
waveguide can also be supplied with a waveguide flange
- All wideband horns are fitted with a convenient mounting
plate and optionally with an aperture window to prevent ingress
of moisture
| |
Dimensions

All dimensions are nominal and measured in mm.
Many other standard wide band
horns are available, or we can design a horn to your specification.
Please include required gain/beamwidth,
frequency range, size etc with your enquiry.
The 3 dB beamwidths are always specified so that the
the first figure refers to the lowest frequency in the operating band.
