• Telescopic aerial repair

    From Liz Tuddenham@21:1/5 to All on Wed Dec 28 15:56:10 2022
    I was given a portable receiver with a damaged telescopic aerial, the
    set had been dropped and one section of the aerial had become slightly
    buckled. and wouldn't telescope inwards. I first thought it would have
    to be either left protruding or written off and replaced with the
    nearest substitute I could find, but later examinatuion suggested it
    might be repairable.

    The first step was to remove the finial; this had been screwed on
    tightly and locked with some sort of compound. By gripping the finial
    in a collet chuck on a lathe and the top section of the rod with a
    strong pair of water pump pliers, I was able to revolve the chuck by
    hand and unscrew the finial.

    The next step was to find a collet that was a reasonable fit over the
    damaged section. By screwing up and unscrewing the chuck ring I was
    able to make the collet gently pinch the damaged area down onto the next
    rod inside it - gradually working my way along and back until all the
    creases had been removed.

    Although the result didn't look perfect, it slid in and out easily
    enough. It just remained to screw the finial back on, with a dab of
    varnish in its threads.

    Job done - cost nil.

    Neat! Congratulations on the "impossible" repair.
    I suppose many of us have kinked telescoping antennas.
    I never heard of one being repaired before - replaced yes,
    un-kinked no. Thanks for posting that. :-)
