Article below is a part of the assembly process of the UHF duplexer – main article is HERE.
Drawing below shows a [AL100] – Coupling Loop Bar RX.
Main purpose of the part is to make a copper loop which engages the signal inside of the cavity. Loop is made of 1mm thick and 4mm wide copper.
DO NOT BEND the last 11mm length – you will do it after assembling the [AL100] – 8mm Aluminium End Cap Top – otherwise you won’t be able to put it through the teflon grommets!!
Please note the TX coupling loops are slightly different, as they work as the notch capacitor!
