Antennas

domo transmitters are supplied as standard without antennas. An

antenna must be connected for normal operation. The transmitter unit is

supplied with a panel mounted SMA connector which carries the RF

output. The antenna should be connected by screwing it onto the SMA,

but care should be taken to not over tighten the connector.

The transmitter has the following RF output characteristics.

Note. It is recommended that the antennas be connected directly to the transmitter unit.

The use of RF cables at this point will degrade the performance of the system.

The optimum choice of antenna will vary according to application. The

following table gives some suggestions for suitable transmit antennas

with the associated domo part number.
