    Roof mount. Flat concrete roof with rebar embedded. About 35 radials of various lengths lying on the surface.

    In that case, put the choke anywhere between the 75 Ohm to 50 Ohm junction and where the 50 Ohm enters the building.

    What issue are you trying to address by adding these parts, and what are you expecting them to do?

    I have chokes at my transceiver feed point, at the feed point just before my coax switch box out in the field, and at every antenna feed point. I have seen at least 2 s unit decrease in the noise floor after adding the chokes.
    KU3X and WA7ARK like this.
