ZCG CM1600-4GX Mast Mount Mobile Phone Collinear 1.85m
ANTENNA DESCRIPTION
With 8.1 dBi gain, model CM1600-4GX offers the maximum gain and reception
range practical in a broadband omnidirectional 4G LTE mobile phone fixed
position collinear.
The white fibreglass radome and 304 stainless steel mount tube stands 1.85
metres tall.
The N-type female connector located at the base of the mount tube is rated for
up to 20 Watts input power.
All components used are of the highest quality to ensure long term survival in
the harshest weather conditions and environments. The antenna will deliver
reliable performance for many years.
Mounting clamps, feeder cable, connectors, cable ties and tape are available
separately to complete the installation.

TUNING
The antenna has been tuned in the factory for all available 4G LTE mobile
phone networks.
VSWR has been optimised to better than 1.8:1 across the full frequency range
700-788 MHz.
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:
- Mount the antenna in as high a place as possible.
- Mount the antenna as far away from other antennas and metallic objects as possible to avoid interference and distortion of the 360O omnidirectional pattern. At least 350 mm side clearance is desireable, preferably more.
- Mount the antenna vertical, not at an angle.
MAST CLAMPS
2 x EB1-SS stainless steel parallel clamps are recommended for mounting to a round mast between 20 mm and 50 mm in diameter. Take care not to over-tighten the clamps beyond reason.
NYLON SIDE MOUNTS
NSM-B20M Nylon Side Mounts are specifically designed to mount this
antenna to the side of a marine vessel’s wheelhouse or any other flat vertical
structure.
Drill a 12.7 mm (½”) diameter hole through the vertical surface for the
stainless steel bolt. Then tighten the bolt to firmly secure the side mount in
position.
Using two (2) of these nylon side mounts, the antenna mount tube is held tight
by the 8 mm stainless steel clamp bolt.

GENERAL PRECAUTIONS
At all times standard OH&S working conditions must be maintained. Use common
sense during all installation work.
Never install an antenna where contact with electrical power lines is
possible. Serious injury or death may occur. Power lines, telephone lines and
guy wires can look the same. Assume any wire or line can electrocute you.
Always wear an approved safety harness when climbing an antenna mast or
working on a raised platform where a fall could occur.
FEEDER CABLE and CONNECTORS
Signal loss can be high at cellular mobile phone frequencies. It is essential
to select a good quality low loss feeder cable according to the length of run
required. Always keep the cable run to the shortest length necessary to reduce
signal loss. RG58 low loss solid core will be the minimum standard of feeder
cable necessary. Where the run length must exceed 5 metres, then RU400 low
loss is recommneded to reduce signal loss and maintain optimum antenna
performance.
Cable preparation trim dimensions for numerous connectors can be found in our
product catalogue. This information is also available to download from the
“Connectors” page of our website.
The antenna feeder cable should be secured so as no stress is placed upon any
connections.
If using cable ties, then we highly recommend the stainless steel type for the harsh marine environment.
****Ensure that connector mating surfaces are not damaged and are clean and
dry. The male connector pin should be set so as to not damage the female
connector pin. Tighten the connectors firmly and make sure they are seated
correctly. The connection should be sealed with two layers of self-
amalgamating tape to prevent ingress of moisture.
****The feeder cable should be earthed to avoid a destructive power surge in the event of a lightning strike.
RETURN LOSS TEST
Following installation of feeder cable, measure the return loss at the feeder cable input and check that there is no major departure from the factory specification using a SWR meter or network analyser.
INPUT POWER
Only operate the antenna at the specified power levels. Exceeding the stated power levels will invalidate the warranty.
MAINTENANCE
The antenna and it’s components have been designed for high reliability and
low maintenance. A routine annual mechanical inspection of the antenna,
connections and feeder cable together with a check of the return loss is all
that is required.
