5 RF Interface
This section describes the physical characteristics of the RF connectors and specifications of
the RF Interface.
5.1 RF Connectors
The Tile RF and GPS connectors are male U.FL connectors [TE Connectivity Part Number
1909763-1]. This is a surface mount connector that is directly attached to the Tile.. A Swarm
VHF antenna must be used, as third party antennas will not be tuned well enough to provide
enough gain and resonance in the specified frequency range of 138 to 150 MHz. Swarm
antennas are tuned for a VSWR of 1.8 or better at both 137 MHz and 150 MHz.
5.2 Antenna Implementation
For illustrative purposes, a picture of two example Swarm antennas is shown in Figure 7
