This Proxmark3 RDV4 LF Antenna Set includes a medium range Low Frequency antenna and long range Low Frequency antenna.
The stock Low Frequency antenna included with the Proxmark3 RDV4 has a read range of between 40mm to 80mm, but the specialized medium range antenna in this kit (which still fits within the RDV4 black plastic snap-on case) pushes that distance to 90mm reliably.
Additionally, the long range Low Frequency antenna included in this kit pushes read ranges up to 120mm.
The Proxmark3 RDV4 has a modular antenna system, allowing for antennas to be swapped depending on your engagement and distance requirements.
