INTRODUCTION
The Proxmark 3 RDV4 has a modular antenna system, allowing for antennas to be hot-swapped depending on your assignment requirements.
The Long Range LF External Antenna Pack containts two high performance, pre-tuned for antennas the Proxmark 3 RDV4, providing the highest read/write/sniff performance possible on an un-amplified external antenna.
Meticulously engineered with 6-layer PCBs, featuring a Frequency Switch and Q Switch – enabling targeting of specific frequencies and badge types.
Q-Switch
The Q-Switch has two settings: 14 (Extended Range) and 7 (Extended Accuracy).
A Q-Switch setting of 14 will give up to 30% further read range (on lf search / lf hid read etc commands).
A Q-Switch setting of 7 will give better writing performance on T55XX and EM410XX tags.
Frequency Switch
The frequency switch allows for tuning to specific tag types: 125KHz or 134KHz.
Performance information is below:
| Antenna Type | Read Distance |
|---|---|
| LF Read Range (Built-in) | 66 – 72mm |
| LF Read Range (medium antenna) | 90mm |
