Com-Power AH-826 Horn Antenna

Frequency Range: 18 - 26.5 GHz

The Com-Power AH-826 is a broadband horn antenna that offers excellent performance over the frequency range of 18 to 26.5 GHz. Most EMI test standards require the use of horn antennas for testing above 1 GHz. Because the AH-826 is linearly polarised, and can be use for transmitting and receiving, it is an excellent choice for both EMC radiated immunity and emissions testing.

Com-Power AH-826 Horn Antenna Product Description

The AH-826 is a broadband, linearly polarised Standard Gain Horn Antenna, operating over the frequency range of 18 GHz to 26.5 GHz. It can be used as a receiving or transmitting antenna.


The AH-826 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, corrosion resistant aluminium. The outer surface is also painted to provide additional protection. The antenna is fitted with a high quality SMA-type coaxial connector.


The AH-826 Standard Gain Horn Antenna is suitable for use as an EMI test antenna for qualification level regulatory compliance measurements (FCC, CE, MIL-STD-461, RTCA DO-160, FDA, SAE, etc.).

The AH-826 is equally suitable for use as a transmitting antenna for establishing radiated RF fields for product immunity tests. It is capable of handling power levels up to 10 Watts with the wave guide to coaxial adaptor in place. By removing the adapter and connecting directly, or with a length of wave guide to your amplifier’s wave guide output, field strengths of over 1,450 V/m @ 1 meter can be achieved with only 200 Watts input power.

Another common application for the AH-826 is to use it as a “substitution antenna” for determining the Effective Radiated Power (ERP) and/or Effective Isotropic Radiated Power (EIRP) of intentional radiators (RF transmitters). These tests are typically applicable for products operating within licensed frequency bands, and also for European acceptance tests per ETSI standards for radio equipment.

Notwithstanding the above, the AH-826 can also be used for site comparisons, shielding effectiveness tests of large enclosures, field monitoring, site surveys and other general purposes.
