VHF Cable
For a long run you may want to use RG213 cable (this has an outside diameter of 10.3mm).
For a short run you may want to use RG58 cable (this has an outside diameter of 4.99mm).
At the controller end you will need to terminate in a BNC plug which are available for both of the
above.
When installing cable it is not just the diameter of the trunking but two areas are critical and the
contractor should be aware:
1) All cables are specified with a Minimum Bending Radius (MBR). Check the data sheet but
this is usua
lly a minimum of 10 times the diameter so for the RG213 above is 103mm (4”)
2)
Kinking or twisting of the cable must be avoided. If a cable is ‘bent’, even when straightened
out again, the internal core will be permanently damaged and cause additional loss and
unwanted signal reflections in the cable.
Customers are advised to make sure that:
1) Their contractor is experienced in installing
and
terminating such cables
2) The cable-ways, ducts, trunking etc. allow
for
easy bends that exceed the MBR and
provide good support
3) The installation work is closely monitored
4) Their installer performs a TDR (Time
Domain Reflectometry) test and presents
this
as part of his certification of installation (the
TDR test will both demonstrate that the
cable has not been damaged and provide
you
with a reference document for future audits
or
checks).
Installation
The diagram to the right gives a suggested
general layout for an aerial installation.
Your installer will be able to advise on the details
specific to your installation.
