(*****) ProxLF antenna for the Proxmark3 RDV4

ProxLF antenna for the Proxmark3 RDV4

Most of this info comes from the DT webpage, but some more info added for the review.

The ProxLF antenna is finally here! Designed exclusively for use with the Proxmark3 RDV4, this 125kHz “LF” antenna is so powerful, it can talk to our 125kHz implants like the xEM and NExT from 2cm away! In some cases it can even talk to the xEM while it is still inside the injection assembly needle!

CAPABILITY

125kHz xSeries implants (xEM, NExT)

Dangerous Things 125kHz x-series implants like the xEM and NExT contain the T5577 chip, which is capable of emulating many different types of 125kHz ID chips including EM41xx, EM42xx, HID ProxCard, Indala, AWID, and others. However the T5577 chip does not support tear protection, so if you attempt to change the configuration of the T5577 without a good coupling (i.e. a good matching antenna on the reader), it’s possible to “brick” the chip so it will not communicate properly.

The ProxLF is specially designed with a cylindrical inductor that shapes the lines of magnetic flux to perfectly couple with the small cylindrical antennas inside the xSeries chip implants!

ONLY COMPATIBLE WITH RDV4

*The ProxLF antenna is specifically designed for use with the Proxmark3 RDV4.

The design of the RDV4 version of Proxmark3 allows for modular antennas, which places the tuning capacitors of the antenna network on the antenna module.

It is not possible to use the ProxLF antenna with any other version of Proxmark3

The ProxLF is made specifically for the RDV4, but there is no specific case made for it, But there are some community mods worth considering

PROs

  • Tuned for xSeries

  • Modular antenna connections

  • “Cheap”

CONs

  • Limited to RDV4 only

PRICE

$35

Summary:

  • Designed and made specifically for Dangerous Things LF xSeries implants, and is a modular antenna that can be swapped in and out at will.

Reduces the chances of bricking your implant.

Tuned for xSeries but still works with cards and likely LF Flexies

Well priced and a capable add on to the RDV4
