The ideal antenna for EMC emissions and immunity testing
The RF516 is a linear polarised Logarithmic Periodic Broad-band Antenna combined with a 4:1 Broad-band Dipole (Aluminium tubing) for Receive and Transmit Applications.
This provides an ideal antenna for EMC requirements, combining high power rating for immunity testing together with the sensitivity required for emissions measurements.
This antenna includes tripod stand and horizontal/vertical polarisation pivot.

Emissions – Antenna Factor
IMMUNITY Field @ 3m. CW,no modulation. Input power at N type connector
Field strength generated under free-space conditions at a separation from the antenna tip (see diagrams for several combinations of pow-er and distance). If environmental reflections are present, this may lead to frequency and height dependent field strengths. The power figures refer to a 50 Ω source and an unmodulated (cw) signal. An 80% Amplitude Modulation requires a 1.8 times higher voltage, re-sulting in 3.24 times higher power compared to cw. A fieldstrength increase of factor 10 requires 100 times amplifier-power.
