Antenna
To prepare the site for the NTP80 installation a suitable antenna location has to be found.
The antenna is a sealed unit. It should be located outside where there is good sky-coverage (e.g.
on a roof) and away from high frequency electrical interference sources. It is highly
recommended to use the fixings supplied and not to make any additional holes for fixing since
this compromises the IP65 rating of the antenna.
The antenna is supplied with 30m of RG58 cable. If longer cable runs are required, it is possible
to use a higher quality cable such as RG213 or RG218.
