JVD-HR4
VERTICAL DUAL DIPOLE FLAT PANEL
ANTENNA
The JAMPRO JVD-HR4 antenna is a half wave spaced dual
dipole vertically polarized flat panel antenna system. Galva-
nized steel panel construction & stainless steel dipole insures
many years of dependable performance. The JHD antenna
has been proven to have excellent bandwidth, with typical
VSWR of <1.05:1 on carrier, and <1.1:1 across the channel.
Many standard and custom directional patterns are available
to fit any of your coverage requirements.
