FEATURES AT A GLANCE
Durable
Easy to install
High performance
The Multi-wire Broadband Dipole Antenna is a 3-wire
terminated folded dipole antenna designed for broadband
operation in fi xed stations. It is available in multiple
power levels up to 1 kW. The Antenna can be mounted
horizontally between two support systems, or as an
inverted “V” using a single central support mast.
DURABILITY
The Multi-wire Broadband Dipole Antenna is made from
lightweight, weatherproof materials designed to withstand extreme
environmental conditions and wind speeds greater than 200 km/h.
The wire elements are constructed of high quality, corrosion resistant
stainless steel, with balun and load housings, and insulators made
from UV resistant, durable moulded plastic.
EASY TO INSTALL
The Antenna is supplied completely assembled and ready
for erection with an inverted “V” mounting arm and detailed
erection instructions.
HIGH PERFORMANCE
Due to the Antenna’s optimum performance over a wide HF range,
an antenna tuner is not required — minimising cost and
setup requirements.
Antenna performance is very similar in both horizontal and inverted
“V” confi gurations.
The inverted “V” confi guration provides a good overall solution
for most base station applications with the added benefi t of only
requiring a single mast for installation.
For long-range operation, the horizontal confi guration
is recommended.
