    "So which band is '0'?"
    "That's the 0m band."
    "What's the 0m band?"
    "This one: HAY YOU!!!! OVER THERE!!!!"
    "what?"
    "YOU'RE FIVE AND SEVEN INTO THE GAZEBO!!!"
    "okay, thanks for the contact"

    My own experiences with fishing rod verticals is simple.

    Just have a length of wire the length of the rod with an L-match antenna coupler at the bottom.

    This will allow it to operate on multiple bands.

    However the wire can't be too short for efficient operation.

    It's better if it's at least 3/16 wavelength.

    If it's 3/16 wavelength (eg 5 metres long on 30 m or 10 MHz) you don't need loading coils.

    You can just tune it up with the antenna coupler. It's near enough to a full sized quarter wave.

    But below that length (eg 1/8 wavelength) it becomes more difficult.

    But you can add a loading coil. Top loading is more efficient but may be mechanically harder.
    I've used centre loading successfully. This can give quite efficient results with it, especially if you're
    not skimping on the length too much.

    Some fishing rod vertical links:

    Interesting counterpoise setup in the last video. I might have to try one. :)
