RF Explorer has recently announced a new addition to their accessories for the RF Explorer spectrum analyzer.
The new model, RFEAN25, is a very sensitive H-loop near field antenna. Lab testing shows the RFEAN25 is at least 10dB more sensitive in the range 20-6000MHz than other H-loop options in the market, at a much lower cost.
A high quality semi-flexible RF cable is supplied and works as the handle of the antenna. The advantage of this approach is you can shape the cable the way you want for the antenna to be located exactly where you need.
