- WEFAX receiving antenna. A six foot diameter, mesh parabolic antenna (see
Figure 10-5). The antenna mounts to a “Patio Mount” and must be oriented toward
a geostationary satellite to receive WEFAX. The Integrated 1691 MHz Linear
Feed/Downconverter, manufactured by Quorum Communications, receives the
signal at 1691 MHz and converts it to 137.5 MHz.

• Software. Three applications are necessary to capture, ingest and display the satellite
data. These are WtCap, WtView, and WtAnim. The GPS0183 Utility is available but
is not necessary to receive data. Each application’s function is apparent in its name.
For example, the primary function of WtCap is to configure the SAT MOD to capture
the data. WtView allows image display and analysis. WtAnim is used to loop
WEFAX images. The GPS0183 Utility allows IMOSS to receive time and location
data from a GPS instrument (not currently an IMOSS allowance item).

METOC software used by the USMC is comparable, and in most instances identical to,
that used by the USN.
