Selecting the antenna type
When no antenna is connected to [ANT2], [ANT3],
and/or [ANT4], these antenna connectors can be de-
activated— by deleting the antenna number from se-
lection. This prevent the transceiver from accidentally
transmitting into an empty antenna connector.
In addition, a receive-only antenna can be specified
for [ANT4].
