ANTENNA DESCRIPTION
The B19-SAR-164-INV VHF high band broadband inverted
mount collinear is constructed from a 304 stainless steel mount
section and a white parallel fibreglass radome with high quality
aluminium and coaxial cable internals to ensure long term survival
in the harsh environment and will deliver reliable performance for
many years.
Standing approximately 1.8 metres tall, the broadband collinear
delivers a 360
O
omni-directional radiation pattern with unity 0dBd
gain.
The N-type female connector jack located at the top of the mount
section is rated for up to 100 Watts input power.
A detailed specification sheet is available to download from
www.zcg.com.au
TUNING
The collinear has been tuned in the factory for the full VHF high
band frequency range 148-174 MHz.
VSWR has been optimised to better than 1.5:1 at the centre and
better than 1.8:1 at the edges
This tuning cannot be altered.
SELECTING THE MOUNTING POSITION
To achieve best performance from your antenna, these are the
important principles you should consider when selecting the
mounting point:
1. Mount the antenna in as high a place as possible.
2. Mount the antenna as far away from other antennas and
metallic objects as possible to avoid interference and
distortion of the radiation pattern. At least 350mm side
clearance is desireable, preferably more.
3. For optimum performance the antenna must be in a
inverted vertical position, not at an angle.
For inverted mounting to a mast, utilise 2 x UAM180L or
UAM180UNI for parallel mounting or 2 x UAM90L or UAM90UNI
for right-angle mounting - order separately.

PREPARE THE FEEDER CABLE
RG213 is recommended for use as a feeder cable. To reduce
signal loss, the cable should be kept to the shortest length
necessary.
The “
7937
” N-type male crimp connector is available to fit RG213
cable. The stip dimensions can be found on our website www.
zcg.com.au
Attach the N-type male connector to the antenna’s N-type female
connector located at the base of the mount section.
Route the feeder cable to your multicoupler or device. Ensure
that the cable is not stretched excessively and there are no sharp
kinks.
If using cable ties, ZCG highly recommend the use of 316
stainless steel cable ties for the harsh marine environment.
Do not pull the cable ties so tight as to crush the cable. A
damaged feeder cable is a cause of high VSWR and reduced
performance.
CONNECT YOUR EQUIPMENT
Cut the cable to the shortest length necessary, prior to fitting the
appropriate connector to suit your devices termination. Once the
cable has been constructed, ensure all termination points are
clean from debris or possible interference.
Connect your cable to your equipment and power on. Note the
performance of your system. If any issues occur power down
immediately and check entire system for faults.
SEALING CONNECTIONS
It is vital that all connections be well sealed with at least two
layers of self-amalgamating tape followeed by a layer of PVC
to prevent ingress of moisture. PVC or electrical tape alone
will not be adequate.
Installation is now complete.
MAINTENANCE
This antenna has been designed for high reliability and low
maintenance. We recommend that you conduct a routine
annual mechanical inspection of the antenna, feeder cable
and connections for bird damage, lightning damage or possible
broken components.
