LINE-OF-SIGHT RADIO LINKS
General. LOS radio links are multichannel digital radio systems which connect all MSE nodes. The LOS radio uses a 15-meter mast antenna system; however, a 9-meter mast antenna may be used to establish an SHF downhill radio link with the switch. There is one 30-meter mast antenna per NC and can be used if the radio link is profiled for it. The AN/TRC-190 assemblages provide these radio links. The radios operate between 225 and 400 MHz and between 1350 to 1850 MHz.
Configurations. The four LOS AN/TRC-190 versions are: (V)1, (V)2, (V)3, and (V)4. (See Table 3-4.) The LOS(V)1 interfaces with a RAU, SEN, FES, and the air defense artillery (ADA) interface unit. The LOS(V)2 interfaces with the NATO analog interface (NAI) converter. The LOS(V)3 interfaces with the NC switch and can be a radio relay or provide a digital NATO interface (DNI). See Figure 3-8. The LOS(V)4 interfaces with a LEN switch as a radio relay and an ADA interface. The AN/TRC-198(V)1 and (V)2 are used in the airborne/air assault, light signal battalion which uses the more compact MSE system, the CCP.

Planning. MSE network planners select the radio band, antenna polarization, site location, and interface used between the LOS and the switch before deploying LOS shelters. The information passes from system control/ battalion control (SYSCON/BATCON) through the MSE network as open link messages for implementation.
