REMOTING CAPABILITIES

TM 11-5820-890-10-8

14.10c. OE-254

SOURCE

The OE-254 antenna is not a part of the SINCGARS radio system and

must be requisitioned separately. Refer to your MTO&E or TDA for the

number authorized.

EMPLOYMENT

This extended range antenna may be used with any configuration of

ground SINCGARS radios, including the manpack version. By both its

height and design, the OE-254 helps to increase the operating range

of any SINCGARS radio.

DUAL USE

When two or more OE-254 antennas are employed in the same

location, a command post for example, they should be separated by

the maximum distance permitted by cabling. When two OE-254

antennas are used with the same vehicle, as during RXMT operations

for example, it is essential that they be separated as far possible.

4.1la. Use of RCU

GENERAL

The Control, Receiver-Transmitter (C-11561), or remote control unit

(RCU) as it is commonly called, provides for remote control of

SINCGARS radios for ranges up to 4 KM. The RCU is connected with

the radio by two-way field wire, and its controls, features and

operation are quite similar to those of the SINCGARS radio. SlP/ASlP

RT can be used as a RCU (LS-685 cannot be used with SIP/ASIP RT

The RCU is a separate issue item, similar to a SINCGARS radio

configuration. RCU details and components (battery box, handset,

and LS-685 loudspeaker) may be found in Appendix B to this manual.

COMSEC

Both the RCU and RT use a COMSEC key (TEK) to provide cipher text

capability. TEK can be loaded into the RCU from an ANCD using the

standard ICOM fill procedure by selecting "RCU" rather than ICOM

from the appropriate ANCD menu.

FH DATA

The RCU does not require FH data. When the net is operating in the FH

mode, FH data in the RT enables frequency hopping capabilities.
