Perhaps because they are the only connector that will fit RG-6? I can't think
of another connector that would fit. RG-6 Is larger, I believe, than RG58 or
RG59.73,Gary K9GS

I am wondering why F connectors are popular in amateur radio stations? Theyare
not waterproof, maybe partially if an o-ring is added. Basically asTerry noted
they are a cheap connector that has no center pin other the coaxwire. John

with my BNC-F adapter for test equipment measurements.REAL F-connectors are an
engineering genius. Low cost, reasonablereliability.This is a result of the two
parallel spring fingers that make up the centercontactin REAL F-connectors.
This accommodates a variety of sizes of centerconductorsfrom different sizes of
coax.The online beauties appear to have a simple machines single-diameter
centercontact, which limits the size of conductor which can be used. This might
beokwith high-precision connectors like REAL SMA connectors, but is a
poormanufacturingdesign when used as an F-connector.I solved the problem with
the supplied PCB connectors by purchasing some external tooth lock washers to
bite into the PVC pipe caps used in the YCCCchoke design. I also used solder
lugs to make the connection to theF-connectors.I could not determine from the
picture in the Digikey catalog whether thepricey Amphenol connector have the
same flawed design. The manufacturer'sdrawingis mute on this important
point.Terry
