Com-Power AH-8055 Horn Antenna Product Description

The AH-8055 is a broadband, linearly polarised High-Gain Horn Antenna, operating with very high efficiency over the frequency range of 800 MHz to 5 GHz. The frequency range can be extended up to 6.5 GHz with some sacrifice in efficiency.


The AH-8055 is designed to be extremely durable, making it an ideal choice for daily use in laboratory environments, both indoors and outdoors, and even under continuous exposure to extreme weather conditions. The antenna is constructed using high grade aluminium with a corrosion resistant conductive coating.


The AH-8055 is intended primarily for use as a transmitting antenna for establishing radiated RF fields for product immunity tests. Its high isotropic gain produces high field strengths with relatively low input power. It is capable of handling continuous power levels up to 450 Watts, yielding field strengths as high as 1,670 V/m @ 1 meter. A graph showing typical field strength values vs frequency, based on the isotropic gain and 450 Watts input power is given on the following page.

The antenna can also be use as a receiving antenna for electromagnetic interference (EMI) testing; however, its focused beamwidth at higher frequencies makes it less than ideal when the antenna height is scanned up to 4 or 6 meters, without changing the angle of the antenna.

Notwithstanding the above applications, the AH8055 can also be used for chamber characterisations or comparisons, shielding effectiveness tests of large enclosures or chambers, field monitoring, site surveys, or other general purposes.
