Equipment used
Anechoic chamber 700MHz ­ 6000MHz

All tests using this arrangement were performed in free space. The return loss at the input of the matching circuit was measured using an Agilent ENA E5071C RF Network Analyser. For all measurements, the relevant sleeve choke was used to reduce the effect of the cable radiation.
