Antenna splitter option
Several receivers can be connected to one antenna via the antenna splitter. Make sure, that the total length of
a route going from the antenna via the splitter to the receiver, does not exceed the maximum cable length. The
splitter may be installed at any position between the surge protector and the receiver.

Compensation the signal propagation time of the antenna cable
The connected receiver must compensate the signal propagation time of the antenna cable, therefore you need
to enter the length of the antenna cable in meters or the compensation time in nanoseconds into the settings
of your receiver.
Antenna Cable Length (m):
The receiving satellite signal is delayed by the used coaxial cable.
Cable
Delay
Usage
RG58U
5 ns/m
for GPS and GNS-UC receivers
H155
4 ns/m
for GNS and GNM receivers
By entering the cable length (from antenna to receiver), the system calculates the delay time and compen-
sates it automatically. The default value of 20 m is preconfigured at delivery.
For other coaxial cable types please use the option
"by delay"
. The delay must be calculated by yourself
by using the information in the data sheet of the respective coaxial cable.
