Amplified antenna for RDV4?
According to the lab401 description for the PROXMARK 3 RDV4 - LONG RANGE HF ANTENNA, it provides the <i>highest read/write/sniff performance possible on an un-amplified external antenna</i>.
I cannot find anything when I search for this, so naturally my next question is: where is this "amplified" antenna that I can buy to extend the range of the RDV4 beyond that of this antenna?
Do these exist?
Thanks!

Re: Amplified antenna for RDV4?
Dunno if someone has an active lf antenna available for sale, dunno if someone is building a active lf antenna, I do know that many want to hook up active long range antennas. The weaponized antennas like boscloner, rfidtastic et al gives 60-100cm lf reading range. Which is quite impressive.

Thats exactly what I'm looking for, except those appear to be for LF only. Does something similar exist for HF?

Somebody has already done it back in 2006.

I guess more people have invented improved versions based on that.
