Requirements for Installing a TCA8000 or TCA8500 Timing Server

This section describes the requirements to correctly install and use the TCA8000 or TCA8500 Timing Server. Table 2 lists the items needed to install the Timing Server.

You must use an appropriate GPS L1 antenna (1575.42MHz) to receive a minimum GPS signal from the Timing Server. The antenna must allow a minimum signal input level of 20 dB with respect to the antenna output for the Timing Server.

Note: To calculate whether the external antenna, cable type, and length meets the minimum TCA GPS antenna input, use the following formula:

TCA GPS signal input = antenna gain – [(cable length) * (cable loss / Meter or Feet)]
