It has a 2.92 mm K (f) connector, measures 74 x 55 x 38 mm and weighs 150 g, and is suitable for both transmitting and receiving in EMC immunity and emissions work.\u003c\/p\u003e\n\n\u003ch2\u003eHigh Input Power for Immunity Testing\u003c\/h2\u003e\n\u003cp\u003eAaronia rates the PowerLOG 40400 at 300 W (peak), 150 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 2:1 (18 GHz to 40 GHz), and the beamwidth is 16° vertical, 20° horizontal.\u003c\/p\u003e\n\n\u003ch2\u003eCompact Microwave Horn\u003c\/h2\u003e\n\u003cp\u003eAt 74 x 55 x 38 mm and 150 g, the PowerLOG 40400 is small enough to sit close to a device under test.
