Antennas
As with any RF device, antenna-related decisions are critical and must be made early. The RF range
of the final product will depend greatly on the choice of antenna and its placement. This module is
available in two versions, selected at the time of order. The On-Board Antenna version is built and
tuned to utilize an on-board F-antenna. The External Antenna version includes a 50-ohm MCX
connector for RF co-ax connection to an external antenna.
External Antenna
An external antenna is connected to the board via an MCX Female coaxial RF connector.
The External Antenna used to qualify the board is a 5 dB whip (shown in Figure 1 - 9.), made by
MMG. The MMG antenna part number is 16-1000-0. MMG contact information is on page 35.

On-Board Antenna
The On-Board antenna design is an F-antenna. This design was chosen because its performance is
more broad-band relative to a slot antenna, and its pattern is somewhat Omni-directional. This
version of the product does not allow an external antenna in conjunction to the on-board antenna.
