CX4-3

Marine and Land Based VHF Antenna


CX4-3 is an omnidirectional dipole antenna. The CX4-3 is manufactured in
premium quality materials in order to prevent galvanic corrosion. Radiating
elements are made of brass.

CX4-3 has been sold worldwide for more than four decades. The antenna is
subject for improvement at all times. The antenna has the same rugged design
as all other AC Antennas products thus it withstands harsh environmental
conditions, both on sea and land.

VSWR

VSWR
Voltage standing wave ratio is a measure of the energy
lost in the coax cable/antenna connection. The figure
to the right shows VSWR measurement based on the
average of a significant numbers of antennas. All
antennas delivered by AC Antennas are tested and a
VSWR less than 1.5 is guaranteed in the specified
frequency range.

Vertical radiation pattern


Vertical radiation pattern for the omnidirectional
antenna at the center frequency. The figure shows that
the antenna has 0 dB gain near the horizontal plane.
