MBD-12F is an intelligent controller compatible with all twelve-antenna switches manufactured by Hamplus. It has a band decoder to receive the information coming from the connected radio equipment. In addition to antenna switching, the MBD-12F also offers eight frequency-driven GPOs (General Purpouse Output), one Band Data BCD Output, one output to command Band Pass Filter, 12 GPOs to automate the operation with TopBeam' s Waller Flag receiving antenna. The MBD-12F also commands the RS-24, RS-28, RS-44, RS-48 Rotator switches.


There are four ways that antennas and enabled rotators can be selected:

1) Manually by the front panel of the MBD-12F,
2) Manually by frequency or band change on the front panel of the transceiver,
3) Automatically by frequency or band change by the remotely controlled transceiver,
4) Automatically by a remotely controlled personal computer via LAN port to the MBD-12F.

On the front panel is a set of twelve illuminated push buttons for manual selection of antennas, twelve "Busy" LEDs to indicate which antennas are in use by other MBD-12F Controllers, eight LEDs to indicate rotator selection, one LED to indicate when the radio is transmitting, one LED to indicate the controller is in Split Antenna mode and one LED to indicate when the MBD-12F is connected to +13.8 Vdc power.
The MBD-12F receives from the transceiver the power supply (13.8VDC), the Send line and the information about the band in use. The controller recognizes the following Radios:

1- CI-V (Icom)
2- BCD (Yaesu and Elecraft)
3- RS-232 (Kenwood, Icom and Elecraft)


Frequency Driven GPO:
The MBD-12F provides eight tuning points for automatically controlling shortened antennas with high Q coils. The tuning points are easily found by the operator using the radio and push buttons

Band Data Output:
The MBD-12F receives the radio information by CI-V (Icom), or by RS-232, or by BCD and provides a BCD output for use in external equipment.

Waller Flag Receiving antennas:
The MBD-12F provides automation for the TopBeam Waller Flag receiving antennas with automatic filter exchange and the addition of an auxiliary keyboard to control the internal four-input Switch.
