Was interesting to see the mentioned duplexer. Notice the non ajustable loop/probe assembly (for insertion loss). Quite the hardware intensive layout...
You probably don't see this type of duplexer construction anymore because the loop/probes are now done the same way using a regular loop on a disc mounting method. The current way is cheaper (of course), easier and more flexible. cheers, skipp www.radiowrench.com/sonic > Neal Newman <[EMAIL PROTECTED]> wrote: > I could not find the old catalog Tom with the Number But said they > were Db products Yes I agree on the 4062's > Neal-ka2caf > > Tom Parker wrote: > > > Mike, > > > > Looks like to me you have a DB 4062.
