5.7.1. ANT - TRANSCEIVER ANTENNA PORTS [1,2]
ANT1 (1) is SO-239 50 ohm connector, while ANT2 (2) is BNC 50 ohm connector.
User can connect transmitter output to ANT1 or ANT2 by properly connecting SMA cable inside the
chassis to one of ANT connectors. Software switching between ANT1 and ANT2 is not available in
HAMlab 80-10 10W version.
Danger
THIS UNIT GENERATES RADIO FREQUENCY (RF) ENERGY. USE CAUTION AND OBSERVE PROPER SAFETY
PRACTICES REGARDING YOUR SYSTEM CONFIGURATION. WHEN ATTACHED TO AN ANTENNA, THIS
RADIO IS CAPABLE OF GENERATING RF ELECTROMAGNETIC FIELDS WHICH REQUIRE EVALUATION
ACCORDING TO YOUR NATIONAL LAW TO PROVIDE ANY NECESSARY ISOLATION OR PROTECTION
REQUIRED, WITH RESPECT TO HUMAN EXPOSURE!
Danger
NEVER CONNECT OR DISCONNECT ANTENNAS WHILE IN TRANSMIT MODE. THIS MAY CAUSE ELECTRICAL
SHOCK OR RF BURNS TO YOUR SKIN AND DAMAGE TO THE UNIT.
5.7.2. AUX1
RX1 IN - direct feed to the first receiver pre-amp and attenuators.
RX1 OUT - an output from the antenna feeding
By default HAMlab 80-10 10W comes with loopback cable connected from RX1 IN to RX1 OUT. User can
also use this two connectors to insert external filters or preamplifier.
Note
This input is not protected by any ESD circuitry, therefore device connected to the RX1 OUT Output is
susceptible to possible damage by ESD from an EMP event if the connected device does not have
adequate ESD protection circuitry.
Warning
Be aware that Preamp1 and Preamp 2 are both wide band amplifiers covering the whole bandwidth of
55MHz. It is not recommended to use the Preamps on a large Antenna without a Preselector connected
(this would cause overload and intermodulation from strong broadcast signals outside the Amateur
Radio Bands)!
