[Elecraft] EH Antenna Patent

[Ron D'Eau Claire]

For superb low noise on HF, don't overlook on-the-ground or even
"underground" antennas as well. While they will be pretty 'punk'
radiators (typically 16 db below a dipole at 50 feet up) they seem to
have very LOW noise pickup and much better signal-to-noise ratios than
most "in the air" antennas. 

The downside is very low signal levels from them - typically 16 dB or so
just like when transmitting - but the K2 has the 20 dB preamp built in
that should make up for that and the 160 meter module offers the
alternate antenna input for a receive-only antenna.

Whether the E-only/H-only explanation is correct or not, the receive 
enhancement is certainly possible on bands limited by external noise. I
use 
my tribander for receiving on 160 & 80 and sometimes on 40. The signal 
strength is much less but the signal-to-noise is often much better than
on 
either a resonant dipole or vertical.
