Care must be taken with the antenna so as not to damage any of the flanges or contacts nor to
chip or scratch the painted surfaces of the antenna.  No special handling procedures are
necessary.

2.3

Power Requirements

The As-1735/SRC antenna has an RF power handling capability of 2 kW Peak Envelope Power
in the 225 MHz to 400 MHz range.  This is inputted through an LC type, UG-352/U RF
connector which is located at the centre of the Lower Feed Section.  No other power sources are
required.

2.4

Cabling

The AS-1735/SRC antenna is designed to mate with the UG-154A/U connector of the
transmission line via a UG-352/U connector.  The transmission line should be tied down to the
mast to prevent excessive stress on the connector assemblies of both the transmission line itself
and the antenna.

2.5

Site Preparations

The AS-1735/SRC antenna has been designed for shipboard use and is intended to be installed
around a self-supporting mast of diameters between 4 and 12 inches (up to 15 inch masts can be
supported by special order).  The Antenna can also be used in shore applications so long as the
installation requirements laid out in this manual are maintained.

2.6

Installation Requirements

Note :

The optimum installation layout for the AS-1735/SRC antenna is determined on a

ship-by-ship basis.  The particular installation plans for the ship should be consulted.

The AS-1735/SRC antenna is designed to be installed around a 12 inch vertical mast.  Four
radiating elements encompass the mast, each 90 degrees from each other and joined by a
common feed point.  Refer to Figure 2.2 for a visual illustration.
