This menu item displays specific options of the reference clock.

Antenna Cable Length (m):

The receiving satellite signal is delayed by the used coaxial cable.

Cable

Delay

Usage

RG58U

5ns/m

for GPS180 and GNS-UC

H155

4ns/m

for GNS180 and GNM

By entering the cable length (from antenna to receiver), the system calculates the delay time and compensates

it automatically. The default value is 20m and the maximum input value is 500m, which must not be exceeded.

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.
