'''Function and Use of the Antenna Switch'''

The '''Antenna Switch''' uses the PTT_OUT from Penelope to switch the antenna either to the Mercury receiver in receive mode or to the transmitter Penelope in transmit mode.
The BNC connectors on Mercury and Penelope are connected with short BNC cables with the RX and TX receiptacles of the switch.

The relays used in the switch are not provided for rf power higher than 100W.
12V at about 100mA are required for supplying the switch and the 6m LNA. You can take the power supply from Atlas.

It is recommended to position the antenna switch in your cabinet so that the DSUB25 Connector is in the same orientation as on Penelope. This allows to connect the flat ribbon cable straight through without crossover. The dimensions and positions of the connectors are shown in a dimension drawing which helps to drill the holes in your cabinet in the correct places.

A straight through flat ribbon cable is connected to the DSUB25 connectors on both Penelope and the switch.

A two wire cable is plugged on a 2-pin connector on the switch for +12V supply i.e. from Atlas.
red=+12V. black=GND.

Additionally there are solderpads for connecting a 6m LNA with short wire cuts (about 10 mm stack distance) to the switch. It can be enabled by Penelope RX Pin 6 in PowerSDR and is then only in the RF-path in RX-mode.

Attention: DO NOT CONNECT THE DSUB25 CONNECTOR TO OZY WHICH HAS THE SAME TYPE OF CONNECTOR AS PENELOPE AND WHICH CAN EASILY BE MIXED UP AS THERE IS NO CODING TO AVOID IT. OTHERWISE YOU WILL SHORTEN +12V ON YOUR SWITCH AND BLOW A TRACE ON THE PCB.

When the flat ribbon cable comes not assembled with loose connectors you have the choice to press the connectors in the correct distance which matches your case configuration. Pin 1 is the couloured wire of the flat ribbon cable and should be connected to Pin 1 of both connectors which have a triangle marking on Pos. 1. Before pressing the connectors on the cable you should be aware that the flat ribbon cable assembly is leaving the strain relieve in the correct direction on both ends.

It is possible to press a third connector on the flat ribbon cable which can be connected i.e. to a power amplifier and configured by means of the TX Pins of the Penelope external control panel in PowerSDR. The control input lines of the power amplifier should then be decoupled by Schottky diodes.

Additional Features for Version V2:

Version 2 has provided the assembly of an additional relay which is grounding the RX connector while transmitting and an additional protection diode in the receive path.

The supply voltage for the 6m-LNA can be switched off by an additional transistor and two resistors when the LNA is not active. For implementing this feature a jumper trace on the pcb is to be removed.
The 6m LNA is enabled through the PenncCtrl table in PowerSDR, HPSDR section:
