10 Channel dbSpectra DECIBEL UHF 450-470 Mhz Combiner Model DB4368-10-B

DB4368 combines 2-10 transmitters as close as 100 KHz with minimum insertion loss.
They are redesigned and reconfigured to provide greater system flexibility, closer spacing of frequencies and easier field tuning for UHF MHz trunking operations

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 returned in 10 minutes instead of an hour.

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

Broadband Performance - This means more available channels!

Compact Packaging - Model construction two channel in all rack space.

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