DB8062F8-B Expandable Combiner
The new Decibel Products DB8062F combines 2-20 transmitters as
close as 150 KHz with minimum insertion loss. They are redesigned
and re c o n f i g u red to provide greater system flexibility, closer spacing
of frequencies and easier field tuning for conventional and 800 MHz
t runking operations.
•M o re 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
a rrangement, and channels can be retuned in 10 minutes instead
of an hour.
•S t a n d a rd i z a t i o n – The combiner uses standard cavity selectivity
settings and standard phasing cables for all models, allowing
f requencies to be added or exchanged easily.
•B roadband Perf o rm a n c e – This means more available channels!
• Compact Packaging – Each channel utilizes a 5x7x12 inch
(127x179x305 mm) thre e - q u a rter wave, high Q copper cavity with
single isolator.
• Field Tu n a b l e – Combiners are shipped factory tuned, but can be
retuned easily in the field with suitable equipment.
