As I'm sure I've said before in this NG, on YouTube there's a Laurel and
Hardy movie from around 1930, where they are making a complete hash of
erecting a wire radio 'aerial' (said quite distinctly). I suppose it is
just possible that that part of the dialog(ue) was dubbed-in for the
overseas market - but I doubt it. Also, in American magazines and
newspapers of the 1920s, in adverts for radio sets etc there is the very
occasional use of word 'aerial'.

Laurel was English and Hardy was American for what that's worth.

I have seen the word 'aerial' in pre-WWII US publications but only when
used tongue in cheek in modern US publications.

In modern US English, you only see the word in conjuction with something
in the air, as in aerial tram.

I have. About the time of the end of World War II I was given a
home-made crystal set by my great-aunt, which she had used back in the
early days of AM broadcast radio in Cincinnati but which she hadn't used
for quite a few years. She referred to the wire thrown down on the floor
as an aerial. She lived about 2 miles from WKRC, 550 kHz and 5 kW, and
maybe 20 miles from super-high-power WLW, 700 kHz which came in even
stronger than WKRC. So a short wire thrown down on the rug was good
enough.

About four or five years later when I got my first ham license my
grandmother also referred to the wire connected to my ARC-5 transmitter
as an aerial. But her daughter, my aunt, called it an antenna. Everyone
else, especially the other radio amateurs I met around Cincinnati,
called the things antennas.

So yes, maybe "aerial" was used by some Americans, several generations
ago.

My great-aunt's Crosley table model radio had a short wave band on it,
and my aunt's large RCA console radio had two short wave bands. The
Crosley had a short piece of wire connected to a terminal on its back,
and the RCA had a length of wire thrown on the floor underneath it.
That's how I first bumped into amateur radio, 75 m and 20 m AM phone
operators. Our grade school library had a book about radio, and I
learned enough by reading it to know that if I wanted to be able to hear
more than clicks and buzzes near the lower ends of those two bands I had
to supply another signal for the CW signals to beat against. So I used
another table model radio placed on top of the RCA, tuned so a harmonic
of its local oscillator would beat against the incoming signal. That's
the only way I was able to listen to code transmissions for a year or
two until I had saved up enough money to get a used Hallicrafters S20R
receiver. That one got an antenna wire running out my bedroom window to
a nearby tree. Six months later my code speed was good enough to get my
first license.

I've kind of liked end-fed wires as antennas ever since, though now I'm
well aware of their limitations, and, with a pacemaker inside me, I no
longer dare use one. Balanced lines and center-fed doublets are a
nuisance when you go backpacking, but I do want to be able to hike back
out to the car afterwards.

Quite. Unfortunately, I can't remember which one said the word.

What is wrong with pacemakers that they can't make one that functions

I would like to endorse that last sentence! In the UK both are
acceptable, and the time when we could dictate what is 'correct'
to the
rest of the English-speaking world is long past.

If we want a 'correct' usage then we need an English equivalent of
the
Academie Francais.

Absolutely. But what I was getting at here is that, while both are
acceptable in the UK, I believe the Americans who tell us that
"antennae" for radio aerials is plain wrong in the US.

PS someone correct me if I'm wrong, but isn't "antenna" the ordinary
peoples' word for a satellite or television aerial in America?
Whereas
everyone except radio specialists uses 'aerial' in the UK. If so it is
not surprising that there is a much more established plural usage in
the
US.

In the US satellite antennas are called a dish and everything else is
an antenna.

I have never heard an American use the word "aerial" in reference to
an antenna.

Also, the thing in the front of a car is a hood, and the thing in the
back is the trunk and the round things, whose color is black, are tires
and the steering wheel is always on the left side.


Well, ok, that's more or less what I said; the languages are
different. "Antennae" is an option in the UK, it apparently isn't in
the US. We are in violent agreement!

# When I first started watching UK TV shows on Netflix and Acorn, I spent
# a lot of time looking up the UK meaning of things to understand what
# the hell the characters were talking about.

# Things like:

# jumble - yard sale or rummage sale
# biscuit - cookie
# caravan - trailer
# porkies - lies
# nick - arrest
# and my favorite, toe-rag.

# Yes, the languages ARE different.

Agreed. Just last night had to look up "grafter".

And plurals are a bit different, depending on whether an "it" or "they" is
implied.
Example: Plessey (it) has a good aerial vs Plessey (they) have a good
aerial.
I never get used to that when in the UK.

I think aerial was used more in the US in the past than now, and I generally
see antennas more than antennae, except on insects.

Lol! Devices that have to work should be designed to work properly in
the very low level fields that occur in every day life. It's not really
hard. There are any number of engineers who can do that.

Here's the list from your reference. Notice that even MP3 players with
earbuds are a risk!



Devices with risk

Anti-theft systems (also called electronic article surveillance or EAS):
Interactions with EAS systems are unlikely to cause clinically
significant symptoms in most patients. However, the American Heart
Association recommends that you:

Be aware that EAS systems may be hidden or camouflaged in entrances
and exits in many businesses.
Don't stay near the EAS system longer than is necessary.
Don't lean against the system.

Metal detectors for security: Interactions with metal detectors are
unlikely to cause clinically significant symptoms in most patients.
However, the American Heart Association recommends that you:

Don't stay near the metal detector longer than is necessary.
Don't lean against the system.
If scanning with a hand-held metal detector is necessary, tell the
security personnel that you have a pacemaker. Ask them not to hold the
metal detector near the device any longer than is absolutely necessary.
Or ask for an alternative form of personal search.

Cell phones: Currently, phones available in the United States (less than
3 watts) don't appear to damage pulse generators or affect how the
pacemaker works.

Technology is rapidly changing as the Federal Communications
Commission (FCC) makes new frequencies available.
Newer cellphones using these new frequencies might make pacemakers
less reliable.
A group of cellphone companies is studying that possibility.
Bluetooth® headsets do not appear to interfere with pacemakers.

MP3 player headphones: Most contain a magnetic substance and research
has documented that placing the headphones too close to the pacemaker
caused interference.

Keep your headphones at least 1.2 inches (3 cm) away from your
pacemaker.
Never rest your head on the chest of a person with pacemaker while
you're wearing headphones.
Both the earbud and clip-on types of headphones can cause interference.
Do not place headphones in a breast pocket or drape them over your
chest.

Extracorporeal shock-wave lithotripsy (ESWL): a noninvasive treatment
that uses hydraulic shocks to dissolve kidney stones.

This procedure may be done safely in most pacemaker patients, with
some reprogramming of the pacing.
You'll need careful follow-up after the procedure and for several
months to be sure your pacemaker is working properly.
ESWL should be avoided in patients with certain kinds of pacemakers
implanted in the abdomen.
Discuss your specific case with your doctor before and after the
treatment.

Magnetic resonance imaging (MRI): a noninvasive diagnostic tool that
uses a powerful magnet to produce images of internal organs and functions.

Metal objects are attracted to the magnet and are normally not
allowed near MRI machines.
The magnet can interrupt the pacing and inhibit the output of
pacemakers.
If MRI must be done, the pacemaker output in some models can be
reprogrammed.
Discuss with your doctor the possible risks and benefits before you
undergo MRI scanning.

Power-generating equipment, arc welding equipment and powerful magnets:
Such as found in some medical devices, heavy equipment or motors can
inhibit pulse generators.

If you work closely with or near such equipment, be aware of the
risk that your pacemakers may not work properly in those conditions.
Follow your healthcare provider's instructions about being around
such equipment.

Radiofrequency ablation (RFA): A medical procedure that uses radio waves
to manage a wide variety of arrhythmias.

RFA is usually performed before the pacemaker is implanted.
Studies have shown that most permanent pacemakers aren't adversely
affected by radio frequencies during catheter ablation.
However, if RFA is performed with a pacemaker, a variety of changes
in your pacemaker are possible during and after the treatment.
Your doctor should carefully evaluate your pacing system after the
procedure.

Short-wave or microwave diathermy: A medical procedure that uses
high-frequency, high-intensity signals for physical therapy. These may
bypass your pacemaker's noise protection and interfere with or
permanently damage the pulse generator.

Therapeutic radiation (such as for cancer treatment): May damage the
pacemaker's circuits.

The degree of damage is unpredictable and may vary with different
systems.
The risk is significant and builds up as the radiation dose increases.
The American Heart Association recommends that the pacemaker be
shielded as much as possible and moved if it lies directly in the
radiation field.
If you depend on your pacemaker for normal heart pacing, your
electrocardiogram (ECG) should be monitored during the treatment, and
your pulse generator should be tested often after and between radiation
sessions.

Transcutaneous electrical nerve stimulation (TENS): A medical device
used to relieve acute or chronic pain with electrodes placed on the skin
and connected to a pulse generator.

Most studies have shown that TENS rarely inhibits bipolar pacing.
It may sometimes briefly inhibit unipolar pacing. This can be
treated by reprogramming the pulse generator

After getting a pacemaker, I chatted with the manufacturer about RF
interference, etc.
The only concern shown was for magnetic fields, and no problems were
expected if the field was removed. I was encouraged to avoid airport metal
detectors mainly because the manufacturer couldn't be sure what kind of
contraption TSA would come up with.

RF ablation didn't affect it. The circuitry seems to be solidly designed.

Your reference contradicts what you say. Are MP3 players "medical"
equipment? I think they are every day devices. If I read the reasoning
correctly, I'd bet holding an old style telephone receiver to your chest
(commonly done to mute it when you are calling for someone to get the
phone) puts a pacemaker patient at risk too. That's the sort of thing
that happens automatically without thinking.
