as accessories.
왘 Connect the remote antennas to the BNC sockets O and R using a low-
attenuation 50-Ω coaxial cable.
왘 If you connect active antennas (e.g. A 3700, AD 3700) or antenna
boosters (e.g. AB 3700), switch on the DC supply voltage for external
active antennas and antenna boosters (see page 31) so that the
LEDs N and/or S light up;
if you do not connect active antennas or antenna boosters, switch off
the booster supply voltage so that the LEDs N and/or S do not light
up.
