Decibel DB4060 Series Duplexers

Jeff Acree All Messages By This Member #214485 What would be required to change a DB4060 series can that is currently set up for pass low / block high to pass high / block low?? If loop replacement is required, where can they be procured? ? Thanks! Jeff KC8VFN
Harold Farrenkopf All Messages By This Member #214492 I haven’t seen the loop but the can uses a T connector and capacitor so if it’s like the Sinclair style Q loop, it’s the same and just needs to be tuned - there is a notch on both sides of the pass frequency.?

Depending on the bandsplit (there are three) and whether the loop is used for high-pass/low-reject versus low-pass/high-reject determines which of the five loop assemblies is needed.? Or to say it another way, for any given bandsplit, two of the five loop assemblies are needed, one type for the high-pass leg and one type for the low-pass leg. ? If the OP will email me what model or frequency range the duplexer is as it stands, I can tell them what to do to convert it to ham band.? I can also provide loops to replace the ones that need to be changed; the trimmer caps are the same regardless so you just need to replace the loop itself.? I can provide cable lengths and other details as well. ? ??????????????????????????????????????????????????????????????????????????????????????????????? --- Jeff WN3A ?
