Re: Elecraft Digest, Vol 103, Issue 26

I have only seen pictures of a Hex Beam so really have no 'feel' for it. In all the oics it is mounted 'bowl' fashion with the curvature up. What would be the effect of mounting it 'down' umbrella style?

If you mount it with the arms curved downward, the problem is
mechanical.  The weight of the arms no longer hold the wires taut, and
the wires no longer limit the amount of curve in the supporting arms.

Consider what happens if the wires and arms are ice coated thereby
increasing their weight - the arms will curve more downward and the
wires will go slack.  With it mounted properly with the curvature up.
that cannot happen unless the weight of ice gets so great that the wires
break.

I'm not sure that's true.  The outward force of the bowed arms would be greater the weight of the wires.  I think they are built that way to get all the height.  And it looks better. IMHO.
