What the picture inside the cavity does not show is the height above the cavity wall the probe assy is.
For the probe cavities, about 15mm worked for me. DO NOT get the probes too close to the plunger.
Rather than glue in a previous picture, my plastic parts were longer with a hole for the probe wire.
I made the magnetic coupled probes also about the same height and they worked.

Build
the T-1507 duplexers and you will be one happy person and the site owner will be
happy too.? Having the isolator/circulator from the transmitter going into the
bandpass filter is the ultimate Intermod protection for everyone on the
site.

The

converted to a T-1507 like they should.? [UTF-8?]It?€?s just the best / proper
way to build a system on a commercial site.

broadcast!
