radio aerial (antenna) won't stay in position

You might as well replace the aerial with a new one. They are so cheap
and the time taken to fit a new one would be exactly the same as it
would be to make a lash up repair.
That would be a practical response *IF* one could find an exact
replacement. Alas, there are thousands of different varieties of these
things, and they tend to be custom-designed for each model. Even
if there were exact replacements in a warehouse somewhere in
central Asia, finding one and getting it shipped to you would be
far less pratical than just tossing the radio and buying a new one.
The OP said it was a Sony. Parts should be readily available for such a
major brand. That said, most of these aerials are pretty much the same
shape and size on even the cheapest brand.

How many of these have you repaired yourself?
Or are you guessing? I'm speaking from first-hand experience.

It now refuses to maintain its position at an *angle*. Slowly but

it drops down until it reaches the horizontal position.

The small screw has been tightened up, but even as tight as we think we
can
do it without stripping the slots in the screw head, it is not enough to
*clamp* the aerial to stop it dropping down.

Basically the aerial at its base is a square shape with one small bronze
coloured washer each side of it and that all sits in a ' U ' shaped base
with it all being clamped with a small screw.

Are there any tricks you know of, to get it to behave? Thanks.

Geez. It`s just gone a bit floppy, the spring washers have lost their
tension, it shouldn`t be beyond the wit of man to either retension them,
find an old aerial from which the springs can be salvaged or if it comes
to it, purchase a replacement aerial from which the springs can either be
used or if he`s lucky enough to find a good match, the whole twig can be
used.

Here in the UK several companies spring immediately to mind who stock
quite a good range of generic replacement aerials, a bit of fiddling will
probably result in a workable solution.

I agree Ron. I've never seen so much nonsense spouted about what is
fundamentally a simple problem, which those of us in the trade see all the
time, and have posted back here how to fix with a minimum of fuss and
tools - certainly not including drills ... !

Take the two washers out and restore the 'curl' in them by pressing them
over the shaft of a screwdriver.
This is the 'correct' fix for the problem - I have had to do it many times
to radios which have crossed my bench, and are similarly afflicted. If you
want to 'belt and braces' it, you can remove the antenna and the curl
washers from the yoke part that stays in the radio, and then treat the yoke
to a *gentle* squeeze with a pair of Mole grips. FWIW, the screw can go up
quite tight without breaking or stripping threads. Also, if you prefer to
work on it not attached to the radio, the connection inside is usually made
by a fixed strap, so you can simply undo the screw just below the antenna
base, remove it completely, and then lift the complete antenna out of its
mounting hole.

Don't forget, with all this mention of glues and paper washers, that
you still want a decent electrical connection between the two bits :)

Nah a condom wouldn't help, even full of helium. Just needs a bit of
fettling, or a new aerial.

I've never seen such a set of ludicrous and impractical suggestions. The
solution is simple. Go to a birthday party and obtain one or more gas-filled

The offshore radio station laser tried that in the 80's and gave up
after the exposure to the winds over the North Sea quickly removed
them . An apocryphal story tells that one ballon ended up around a
traffic bollard in Colchester.

In either case, you seem to be in a better position to match replacemnt
antennas with consumer equipment. I'm happy for your success.

If a quarter is 25 cents, how does that work Michael ? Presumably not
possible to have one bit ? Nothing cheaper available than a two-bit whore ?
