In the 11m band the antenna can be extended simply by touching the antenna.
This is because the human body is basically a saline conductive material and
the size of the human body approaches 1/4 wave for these frequencies (that
is why RF safety only allows 200 watts max at these frequencies). It might
be worth a try to extend the antenna by using conductive material onto the
surface of the mouse so it is possible for the user to touch the antenna
input connection. This could improve the gain of both transmission and
reception, that is, if it is actually in the HF 27MHz range



If loading of the "final" doesn't cause significant detuning and results
in worse performance ...
