Re: DB4060 Series Dfor a 4-cuplexer Cans
¿ªÔÆÌåÓýTim,
From the information here on the group and referencing , a factory B range 4060 or 4062 requires "004" in the Low Pass and "005" in the High Pass.? So - you should be good to go... The screws are SAE - but I don't remember the size. Kevin On 4/19/2025 12:46 PM, TIM HARDY via groups.io wrote: Hello, I checked the loops on my 4062 cavities to verify the range of the duplexer. The HIGH pass cavities used loop "005", LOW pass used loop "004" Am I correct to assume this duplexer is a "B" range? (Factory set to 149.825) Sure hope the duplexer will be usable at 146.xxxx mHz! One more question. I lost one of the Phillip's head stainless screws that hold the loop box to the can. What size are they? Are they metric?

There is no difference between the 2 sides except how you have it tuned.Wrong. The loops are different between high-pass and low-pass. And, the loops are different depending on bandsplit. If you don't have the right loops, or are using the loops for the wrong response (high-pass versus low-pass) you probably won't even make rated space for notch depth. If they are correct for the bandsplit and pass response you'll get 85 dB for a 4-cavity DB4060. --- Jeff WN3A |
