I don't know if it was published.. Set your cans for 0.9dB IL each and your end result will be 3.2dB. The notch cavity should be set to maximum depth unless you have a very close frequency down the chain (<0.5MHz away).The notch is tuned to the pass frequency.
The 3 pass cans will produce 3 return loss dips - remember to use a load on the unterminated ports of the filter when using the RTB. I can't locate the length of the cable between the pass cans but I think my memory is saying 23 inches tip to tip. --- In Repeater-Builder@yahoogroups.com, Larry Horlick <llhorl...@...> wrote: > > Harold, > > I used 2 cans in my initial post for simplicity.
