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 satellite and GPS connectors are male U.FL connectors
[
. This is a surface mount connector that is directly attached to the Tile. A Swarm
VHF antenna must be used to ensure that the RF output is within certification limits. Swarm
antennas are tuned for a VSWR of 1.8 or better at both 137 MHz and 150 MHz.
5.2 RF Connectors
For illustrative purposes, a picture of two example Swarm antennas is shown in
