Two helical antennas were designed, fabricated and
tested to permit tanks or tracked vehicles to function
with a high gain, low profile antenna field pattern
for a telemetry system operating at 518 MHz. The
electrical properties of the helical antennas were
compared to the system's dipoie antennas in an attempt
to enhance the operating performance of the RMS
II/SCORE system. Field measurements were made under
the controlled conditions of an antenna field pattern
range and while the RMS II system was operational.
Antenna properties of gain, beamwidth and efficiency
as well as physical size and installation locations
were considered for possible inclusion of helical
antennas in the telemetry system.
