Antenele de banda larga, in comparatie cu cele half wave dipoles, reduc timpul de testare deoarece tehnicianul nu trebuie sa se opreasca din testare pentru a regla antena dipol pentru fiecare frecventa. Cele mai multe standarde de conformitate solicita acum folosirea unor astfel de antene. Cea mai noua versiune a standardului Mil-Std 461E specifica folosirea antenelor horn de banda larga double ridge guide ca si alegere pentru antenele folosite la frecvente peste 200MHz.Antenele Horn Double Ridge Guide sunt antene A.H.Systems de banda larga, care ofera performante excelente in gama de frecvente 170 MHz - 40 GHz. Aceste antene sunt o alegere excelenta pentru testarea imunitatii si emisiilor de radiatii. In continuare prezentam cateva modele de antene horn double ridge guide, ideale pentru majoritatea testelor de conformitate si/sau masuratori generale de camp:

Standard Gain Horns
The Standard Gain Horn Antennas are designed specifically for utilization in emissions and immunity testing over the frequency range of 1 to 40 GHz. Each antenna is linearly polarized and has medium gain, low VSWR, and constant antenna factor. The Standard Gain Horn performance is very precise and predictable through design parameters. Comparisons of measured versus computed antenna factors and gain have been shown to be +/- .5 dB. Therefore, the antenna is considered to be a standard reference, similar to that of a resonant dipole below 1 GHz. The coax-to-waveguide adapter is the only power-limiting component on the antenna and can be removed if high fields are desired. Each Standard Gain Horn comes with a tripod mount that adapts to any tripod with ¼-20 male threads. Horizontal and vertical polarization is obtained by rotating the antenna on the tripod.
Gain: 15 dB, also available in 10 dB or 20 dB gain.

Octive Horn Antennas
The Octive Horn Antennas are linear polarized, medium gain and low VSWR that cover the 1 to 8 GHz Frequency range. These antennas are designed to match the operating frequency of most octave bandwidth amplifiers that are typically used for compliance testing. Having an equal half power beamwidth in both polarization is ideal for compliance tesing, this allows the user to accurately illuminate the equipment under test in both horizontal and vertical polarizations. Each antenna is supplied with a tripod mount and waveguide to coax adapter. These adapters limit the maximum power handling capability. Without the adapter, these antennas are capable of handling continuous power well above 10,0000 Watts.
Model Frequency Range Description Gain
