Hi guys Just updating on the 6mc450s style notch duplexer problem.We found
one of the 6 tuning insulators inside were burnt through the insulator so we
got the local engineering group to lave another insulator out of nylon rod
and have put it back together and tested it on the service monitor and i
Hi again guys .This has been brought up before I know but I thought I need
to ask this .With the length between the transmitter and diplexer should we
keep the cable as short as possible because I seem to find I have more loss
with longer rg223u cables (aprox 1 meter ) .I tried a isolator inline an

In an attempt to address a hard 3rd order issue apparently being
caused by a Motorola Radius repeater (no circulator and a cheapie
internal notch "duplexer").
Background:
Repeaters A and B share a properly engineered combiner system which is
working well at 4 other sites. At this site a repeater
I keep hearing about these "Z-Matchers". Who makes them, and are they expensive?

Ian,
The cable length is more important on the TX side than on the RX side. However, since the impedances of the power amplifier output and of the duplexer TX input are seldom known

Is it nessary to have the corr
Is it nessary to have the correct length coax from the diplexer to the rx and tx or is there a formular that can show the correct length .I am currently using RG223 coax for these links

Hello there,
I'm looking for some help with a UHF Decibel
Products DB4076W Duplexer, in specific the
coax cable lengths if one of you can measure
and provide them from your same model unit.
This duplexer is Decibel's round UHF BpBr "four
bottle" assembly, the suffix -004 (dash no) is
for
10 matches
