[Elecraft] Experiences using a portable HF loop

[Ron D'Eau Claire]

The very BEST magnetic loops are incredibly inefficient, yet like any
"incredibly inefficient" antenna one can make amazing contacts on them when
conditions are right. 

The problem is with resistive losses. The day we have room-temperature
superconductors, we will have efficient small transmitting loops. Until
then, only a few percent of the power applied is radiated. 

For now, they are great when simplicity of setup allows operation where
otherwise nothing could be done.

The May 2017 QST not only does a review of the Elecraft KX2 but it reviews
the Alpha Antenna, 10-40 meter support.  This is a magnetic loop antenna and
I think it retails (basic model) for $299.

opinion about them? How efficient these antennas are, especially running
qRP.
