Antenna cable
If you are using the TT-3020C Transceiver with a TT-3001B opt.
001 antenna with N connector, use cable with N and TNC con-
nectors. The specification of this antenna requires that the total
maximum attenuation at 1.65 GHz must be less than 16 dB, and
the maximal total (short-circuited in one end) DC resistance must
not exceed 0.7 Ohms.
In case the antenna cable is to be produced on site, the cable
type should match the below listed guide-lines:

All antenna cables types are double shielded.
The antenna cable may run together with radar or navigator ca-
bles. Separate cable ditch is not required.
