Eric, The DB4055 is 5 cavity band reject duplexer from Decibel Products.
Its notch is 75 to 80 db at 5 MHz. Min freq separation is 5 MHz making it useless for 2 meters Ham repeater. TX noise suppression at RX freq 70 db RX isolation at TX freq 70 db. Max power is 150 W continuous and insertion loss is 0.7 db. The versions ar A=150-162 and B 160-174. Would be good for something like MARS or other commercial repeater. 73, ron, n9ee/r >From: Eric Grabowski <[EMAIL PROTECTED]> >Date: 2008/04/04 Fri AM 03:29:17 CDT >To: Repeater-Builder <[email protected]> >Subject: [Repeater-Builder] DB4055 Duplexer > >I found tuning instructions for the DB4055 duplexer on >the R-B website, but I haven't been able to find any >specs on this unit. > >Does anyone know what the insertion loss and maximum >power ratings are? > >Is the low-split version suitable for use on 2 meters? > >73 and aloha >Eric KH6CQ > >__________________________________________________________ >You rock.
