WISCO International (Decibel Products DB8062F)

DB8062F8-B 851-869 MHZ,
8-CHANNEL TRANSMITTER COMIBNER

The Decibel Products DB8062F combines 2-20 transmitters as close as 150 KHz with minimum insertion loss. They are redesigned and reconfigured to provide greater system flexibility, closer spacing of frequencies and easier field tuning for conventional and 800 MHz trunking operations.

More Output Power � Up to 500 Watts with N-Female connector, up to 1500 Watts with 7/16 DIN.

Easy Field Tuning and Expansion � Any channel can be tuned at any port! This allows channels to be added or exchanged in any arrangement, and channels can be retuned in 10 minutes instead of an hour.

Standardization � The combiner uses standard cavity selectivity settings and standard phasing cables for all models, allowing frequencies to be added or exchanged easily.

Broadband Performance � This means more available channels!

Compact Packaging � Each channel utilizes a 5 x 7 x 12 inch (127 x 179 x 305 mm) three-quarter wave, high Q copper cavity with single isolator.

Field Tunable � Combiners are shipped factory tuned, but can be retuned easily in the field with suitable equipment.
