Re: DB4032 duplexor

Tedd,
I use on of these on my repeater. I got some conversion info from an
Engineer at Decibel
back in 95. The drawing is not an offical engineering drawing and has a
number mkt019/a
on it you might see if you can get it.
Cable measurements are cut lengths, connectors not included
Open the cans and trim the helix to 7 1/4 turns.
Pop rivet the cans back together
on the low freq side...
Can to Tee length 14 3/4
Shorted stub length 19 1/2
Interconnect (Qty 2)
29 1/2
On the high freq side...
Can to Tee length 29 1/2
Open stub length 21 1/2
Interconnect (Qty 2) 41 3/4

For the arms of the Y cable at the antenna port
41 3/4 Qty 2

I used the long stub to make the short ones.
I made new long stubs
I did not change anything alse in the harness as it was darn close and
it works for me.

If you cant get the document from decibel I will send you a copy.

Hi Guys:

Anyone know where to find out cable lengths (open stubs,
shorted stubs) within the DB4032 duplexor? I have parts
of the owners manual, but what I need is missing.

The repeater is going on 53.37 tx, 52.37 rx.
