Radio assembly types
The radio assembly is not part of the antenna kit; however, radio 
assembly installation is included in this manual because the 
antenna and radio assembly are usually installed at the same time. 
There are two possible radio assemblies available for the   .98 m 
antenna, the J-type radio assembly or cradle-type radio assembly. 
J-type radio assembly Figure 10 shows the J-type radio assembly, referred to as J-type 
because its waveguide is shaped something like the letter J.   
J-type refers to the overall design of the radio; therefore, two 
radios with different model numbers may both be J-type radios.
Vertical shim kit (if required)
A vertical transmit shim kit may be required for the J-type radio 
assembly only. If the installation specification states that vertical 
transmit polarization is required, you will need to obtain and 
install a vertical shim kit (Figure 11) in the radio assembly. 
Otherwise, a vertical shim is not required. For more information,
