8.0 INSTALLAING VERTICAL SHIM KIT FOR THE RA6-074 RADIO
Out of the box the radio assembly is configured to transmit with horizontal polarization. However, the
radio assembly can be reconfigured in the field to transmit with vertical polarization. A Vertical TX Shim
Kit, HNS model # VTX-SHIM-KIT, is necessary to make this transformation and is typically packaged
separately from the radio assembly. Figure 22 illustrates the vertical shim kit. If your specifications
require a vertical transmit polarization, follow the instructions below.

If the radio assembly is already attached to the feed arm you must remove it by removing the
screws and bolts shown in Figure 23.
