Antenna cable
Use a 50 ohm coaxial cable with a male TNC connector in the antenna end and a male
SMA connector in the receiver end to connect the antenna to GTM. Choose cable type
and length so that the total attenuation is max. 26 dB at 1.6 GHz.
Make sure that the antenna cable is not charged when connected to the
antenna or to the receiver. Short-circuit the end of the antenna cable
with some metal device, when first connected to the antenna. When
the antenna is connected to the cable, connect the cable to the receiver.
The IED must be switched off when the antenna cable is connected.
