RF-1938
PORTABLE CROSSED
DIPOLE ANTENNA
for NVIS (near vertical
incidence skywave)
communications
The RF-1936/38 Series of antennas are man-portable
and rapid-deployable for NVIS communications.
The NVIS communication mode is for paths from 10 to
400 km. This communication mode is particularly
useful in mountainous, heavily wooded terrain, or dry
sandy soil where groundwave is limited. The RF-1936 is
used for general purpose NVIS communication links out
to 400 km; while the RF-1938 is designed for the hard
to close 10 to 200 km links.
These lightweight antenna systems are easily carried
and installed by two people in five minutes (RF-1936)
or 15 minutes (RF-1938). The sectional mast is a low
loss coaxial feed line to feed unequal length crossed
dipole radiating elements. The radiating elements are
attached to guy ropes that provide mast support. The
entire antenna stows within a small canvas bag. The
RF-1938 has a second set of coaxial masts and guy
lines which stow within a second canvas bag.
