Page Two - ---- When When designing a system, a major requirement is to keep• the'inser- tion loss of the.duplexer and filters as small as possible.. As the system insertion loss increases, the"talk-out and talk -back of the system decreases. Using our computerized range evaluations, the 'following capabilities can be.expected: Company - - Talk=out; Miles Talk Back; Miles RCA __ 20.2 19'.8 �. General Electric 22..2* 22.2 Motorola --- - Undetermined Undetermined Therefore, from-thegiven information the GE system has a slight �..t. advantage over -RCA,' on both base talk -out and mobile talk -back. Motorola did not supply adequate information and consequently can not•_be considered. -- _ If you decide that the losses are too high in the RCA system, Motorola. should be asked to state the duplexer proposed for their system. General Electric turns out to be the high bidder when costing in their MASTR II, which meets the specification. Therefore, RCA and Motorola should be.given first and second consideration. -If selection of a compliant bidder proves to be difficult using the given specifications, you might -consider rejecting all bids, then using a set of -specifications developed by this office.
