CONNECTIONS
2.1 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 and/or use an ATU.
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 using a receiving antenna may damage it.
Warning!
i Always use E-type ferrite beads on antenna and other cables, connected to the
transceiver!
2.2 Grounding
To eliminate the risk of electric shock it is essential to use a reliable grounding connection for
the transceiver.
Warning!
i Never use water or gas pipes for grounding!
i Never use the MB1 transceiver without reliable grounding!
2.3 AC power
Connect the transceiver to the AC mains network with the power cable supplied with the
transceiver. Make sure, that the power outlet has the grounding/earth terminal and that it
matches the type of the power cable in use.
Warning!
i It is recommended to set the E-type Line Filter on the Power Supply cable near the rear
panel of the transceiver.
