30-1,,000 me Antenna Development
1. On February 1 0 a call was laced to
2. According to one antenna has been completed and -Du ing tested electrically. r testing it was found that the metal mast
supporting the antenna interfered with proper antenna operation when
in vertical polarization. The effect of the metal mast was negligible
when the antenna was operated in horizontal polarization. To remedy
this fault, a special eight foot mast has been constructed which
eliminates pattern breakup. The new mast consists of alternate sections
of metal tubing and plastic tubing, so arranged as to effectively break-
up interferring currents in the mast. The new mast is constructed so
that the socket at the bottom is an exact duplicate of the socket on
the antenna, allowing the use of a conventional mast connected either
to the antenna directly when using horizontal polarization or to the
special mast when using vertical polarization.
