RF Explorer Near Field Antenna Kit is a collection of high-performance set of 4 antennas designed for the most demanding RF diagnosis tasks:

  • RFEAH-25 – 25mm H-Loop

  • RFEAH-15 – 15mm H-Loop

  • RFEAH-5 – 5mm H-Loop

  • RFEAE-10 – 10mm E-Field

The three magnetic H-Loop antennas are very sensitive, compact and easy-to-use antennas for all sorts of radiation sources. As the antenna diameter gets shorter, the antenna increases spatial resolution at the cost of some sensitivity loss; you should select RFEAH-25 for best sensitivity with connectors, large ICs and isolated signal traces, whereas RFEAH-5 works best for very narrow selective work in a populated PCB with close-by signal traces. RFEAH-15 is a good in-between compromise.

The electric field RFEAE-10 offers a remarkable spatial resolution to determine the exact component in the PCB causing a problem, no matter how small it is.

The low loss design of these antennas exhibits at least 10dB more sensitivity than other near-field antennas in the market, at a much lower cost.

Compared with other near-field antennas, RF Explorer is smaller and lighter, exactly what fits best when space is constrained in a PCB. 

Included with the antenna is a high-quality semirigid RF cable; this cable works as the handler of the antenna. The big advantage of this approach: you can shape the cable the way you want for the antenna to be located exactly where you need it, in most cases with no need to hold it in your hand.

The RF cable is coupled with a fast, easy-to-use SMA Push-On adapter so the different antenna models can be easily plugged in/out as required for the task. There is no need to deal with SMA nuts, just plug-n-play antennas.
