The Aaronia PowerLOG 70180 is a double-ridged horn antenna covering 700 MHz to 18 GHz, with 2 to 17 dBi gain and a maximum input power of 500 W (peak), 300 W (CW). It has an N (female) connector, measures 235 x 252 x 175 mm and weighs 1400 g, and is suitable for both transmitting and receiving in EMC immunity and emissions work.
High Input Power for Immunity Testing
Aaronia rates the PowerLOG 70180 at 500 W (peak), 300 W (CW), which is why it suits radiated immunity testing where an amplifier drives the antenna to produce high field strengths, as well as receive work. Gain rises across the band to 17 dBi, typical VSWR is below 3:1.
Broadband Coverage From One Horn
One dual-ridged horn covers 700 MHz to 18 GHz, so a sweep across the band needs no antenna change. The N (female) connector suits high-power cabling. The housing measures 235 x 252 x 175 mm, the antenna weighs 1400 g, and Aaronia gives an operating range of -40 °C to +85 °C and 0 to 95% relative humidity.
Calibration Data Included
Specific calibration data and a mounting plate are included. With the antenna factor applied, the spectrum analyser reading converts to field strength, and in transmit use the gain figures let you work out the field strength produced at the test distance.

Limitations
- A horn is directional: it must be aimed at the device under test, and its coverage at short distances is limited by the beamwidth.
- Transmit use is subject to local radio regulations.
- At 1400 g and 235 x 252 x 175 mm it needs a solid tripod or mast; Aaronia recommends its heavy tripod.
- Typical VSWR is below 3:1, against below 2.5:1 for the 10800.
