Hi Stephanie -- I was just looking at your web site (nice job, by the way)
and had one of those "Eureka" moments.  In describing your guying
arrangements, you say that you have a set of guys at the 30-foot level that
are connected electrically to the tower and to ground, for lightning energy
absorption purposes.

This is probably the biggest reason why your half-sloper won't work.  As
N4KG said, the tower is most of the radiating structure in these antennas,
and you have a ground situated half-way up.  At a minimum, this will make
the radiating part of the tower appear much shorter electrically than it
would otherwise, and who knows what else?
