[Antennas] ER biomedical equipement antenna?

[Eric Lemmon]

John,

Ask the person who made that claim to explain his or her rationale.  You
might also make a table of harmonics, using 3.860 MHz as the base, to
see if any of them fall on a frequency used for medical radio, physician
paging, or wireless patient monitors.  There are dozens of medical
diagnostic tools which use RF at various frequencies, and the specific
frequencies may not be revealed in the service literature- but which may
suffer interference from an AM or SSB signal.

I infer from your question that you intend to operate on a single, fixed
frequency.  If you will operate on a number of different frequencies,
the potential for random interference with sensitive medical equipment
is high.

I suggest that you proceed very cautiously in this endeavor.  If there
is the slightest possibility that your HF emissions can endanger
patients, either directly or indirectly, I'd put the radio somewhere
else.
