[Elecraft] K3 Below 500 KHz RX Antenna

[Joe Subich, W4TV]

Actually, if you want cheap and effective look at the PA0RDT mini-whip
active antenna:

The active antenna is relatively small and easy to build with no
particularly expensive or difficult to find parts.  Some builders
have even used MPF-102 and 2N3866 or 2N3904 transistors instead of
the U310 and 2N5109.

73,
