NOTICE:
Proper surge protection should be installed on RF inputs to prevent potential damage to the
MTS. See Surge Arrestors and Suppliers on page 488 in
Field Replaceable Units (FRUs) on
page 478 for more information.
The antenna connectors are DIN 7–16. The center connector is usually silver coated, the outer
body is usually aluminum or silver. It is recommended that mating antenna feed connectors
match metal plating correspondingly.
The screens of the antenna cables have to be grounded near to the MTS in accordance with
the R56 guidelines and national standards.
