REAR PANEL DESCRIPTION
Use it to set the transceiver in the boot mode.
LAN connector for connection of the transceiver to the local
network via the LAN cable.
Not used in series devices
3.1 Antenna
Before connecting the antenna, check the integrity of the antenna-feeder path.
For best results, the antenna should have an impedance of 50 Ohm to match the 50 Ohm
impedance of the HF nodes of the transceiver.
The antenna should have SWR level not worse than 1.5:1. If the SWR is worse than 1.5:1,
match the cable and the antenna to the desired level.
Note:
·
Using a mismatched antenna-feeder path might cause non-linear distortion of the transmitted
signal, HF interference on the transceiver's cables and/or interference of TV's or other
devices.
·
Transmitting with a receiving antenna may damage it.
Warning!
i
Always use E-type ferrite beads on antenna and other cables, connected to the
transceiver!
3.2 Grounding
To eliminate the risk of electric shock it is essential to use a reliable grounding connection for
the transceiver, the best grounding point is the antenna connector.
Warning!
i
Never use water or gas pipes for grounding!
i
Never use the SunSDR2 DX transceiver without a reliable grounding!
