Antenna Cable Length Delay
The RG 213 propagation delay is 1.54 nanoseconds per foot (5.05
ns/meter). The LMR 400 propagation delay is 1.2 nanoseconds per foot
(3.93 µs/meter). Given these delay values per foot you can calculate the
delay for your cable length.
Tables 2-1 and 2-2 list the delay values that you need to use with the
:GPS:REFERENCE:ADELAY <seconds> command for the available
cable assemblies.
