RF Explorer Near Field RFEAH-25 Antenna Datasheet Description 1 RF Explorer RFEAH-25 is a 25mm diameter, high performance near field H-Loop antenna. RFEAH-25 is a very sensitive, compact and easy to use H-loop near field antenna. The low-loss design exhibits at least 10dB more sensitivity in the range 20-6000MHz than other H-loop options in the market, at a much lower cost. Compared with other near field antennas, RFEAH- 25 is smaller and lighter, exactly what fits best when space is constrained in a PCB. Included with the antenna is high quality semi- flexible 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. 1 Note: First production batch defined the antenna reference name as RFEAN25, whereas second and newer nd batches renamed as RFEAH-25. Except from CNC cut details on PCB edge (smoother in 2 and newer batch), both antennas are identical. They both have same electrical performance.
