Full wave antennae on 137kHz?
 

Drove onto the field on Tuesday and was dismayed to
see a big banner marked Tomlinson, which portended
a bum job, but it turned out to be a scorcher being
a fence judge at the Dauntsey horse trials.

Taking my cue from the coupling loop that feeds a
mag loop antenna, and sitting pretty much under
the 400kV pylon line, I wondered about the possibility
of using a loop to couple into the electricity grid and
so giving the equivalent of a Beverage at 137kHz?

If it does work, reciprocity is right out of the window.

COnsidering that in the US the LF bands aren't yet available because they
need to deal with the power company using low frequencies over the power
line, you might end up causing interference.

But also, there was all that power line communication in the past
(university radio stations, intercomes, remote speakers and I forget what
else) but it stayed mostly on the power line. You needed to be relatively
close to the AC wiring to get the signal. Though maybe long distance
power lines are different.

Aren't you more likely to have success using a fence around a farm?
Though you need the right location, and maybe the right neighbors.


But what did they do in the old days? Everyone was down below the current
AM broadcast band in the early days, which is why hams were banished to
the "useless" shortwave frequencies. Did they have full length antennas
back then, or make do? They did try for long antennas but surely many
couldn't fit a full length antenna. But I'm sure lots of magazines from
the early days would turn up useful things, if you've got the space.

There is a lot yet to be fully understood about access to the LF bands
in the US. But if you are under a HV line, they might well be using the
line for carrying control signals for the power grid. The technology,
PLC, doesn't play nicely with ham usage.

How do you find whether a power line is using PLC? For some reason you
can't find anywhere a list of places that are OK, or that are not OK.
Instead you have go to a website and ask, and wait to be told yes or no.
So we (the hams) are in second place when it comes to sending
information over these lines.

(There is a fairly new line at something like 250KV close to my back
yard. I don't yet know whether it is carrying PLC.)

If I remember correctly from my time working on the design of
grid control systems (40 years and counting), it's known as
Pilot Protection and its loss may be the first indication of
a line going down.

How do you prevent your transmissions from passing through the

As far as I know, in the USA we only have to inquire before operating
if we're located within 1 km of a power line.

The only hams that can use those LF bands in the US have special
permission, like the exemption given to early SSTV experimenters.

The ARRL had a notice just a few weeks ago about how the LF bands are
otherwise off limits until some issues have been worked out. It's related
to informing the power company or something like that. But it's not in
place, so the bands can't yet be used without that special authorization.
I'm not even sure if the FCC is issuing more of them.

We have the bands here in Canada though.

Well, we've both made our positions clear and there is no common
ground between us. Let's leave it there.

Yeah, right, using my own antennas on my own land is just the same as
going onto the utility easment and setting up equipment to use the utilities
equipment.

ITYM, "antennae"

It is "antennas" for the things connected to radios and "antennae" for
things connected to insects and arthopods even in the UK, not just in the
US, according to Collins English Dictionary.

Arthur Collins was in the dictionary business besides making radios?

Taking my cue from the coupling loop that feeds a

There is a lot yet to be fully understood about access to the LF bands
in the US. But if you are under a HV line, they might well be using the
line for carrying control signals for the power grid. The technology,
PLC, doesn't play nicely with ham usage.

How do you find whether a power line is using PLC? For some reason you
can't find anywhere a list of places that are OK, or that are not OK.
Instead you have go to a website and ask, and wait to be told yes or no.
So we (the hams) are in second place when it comes to sending
information over these lines.

(There is a fairly new line at something like 250KV close to my back
yard. I don't yet know whether it is carrying PLC.)
Bob Wilson, WA9D
As far as I know, in the USA we only have to inquire before operating
if we're located within 1 km of a power line.


Whereas here in Brit we have restrictions within 1/2 mile of any aerodrome.

But that's a restriction on antenna height (40 feet, I believe - but as I
don't live within 1/2 mile of an airfield, I haven't checked lately).

And it has nothing to do with technical matters, it has everything to do
with not getting in the way of the airplanes.

There was a similar law in Canada when I was licensed decades ago. I
assume it hasn't changed much, but I've never lived near an airport
either, so it never applied to me.

Interpreting that, it does bear out Gareth's theory that antennae is the

that antennas is growing in popularity.

Do they restrict the height of trees as well?

Near my house the city wanted to extend the runway. The main road in and
out of town passes within some hundred(s) of feet of the end of the run way
with power lines. Someone paid to bury the power lines and they cut the
lighting poles down to about 7 feet as well as clearing a vacant lot across
the street. They even bought out a Waffle house a couple doors down the
street because it would have been too many people in the area around the
flight path. Some other businesses were allowed to remain because they
didn't have as many people in them typically.

The part I don't get is how they can ignore the traffic on that road.
School buses run by there every day full of kids and standing taller than
the lighting poles. I don't get how all this was reasoned out, why one
thing would be mitigated and other things not.

I'm an optimist living in a constant state of disappointment. But,
seriously, while Gareth is 70 years (and a major war with technical
cooperation on the allied side) too late to get rid of 'antennas', there
is also a respectable history of use of 'antennae' in a radio context,
albeit a dying usage.

Oh dear, turning to fowl language hardly shows your command of English,
nor that you can conduct yourself in a civil manner.

Don't take your frustration out on others when you've been proved wrong,
that is exactly what your chum did and look where that ended up- him in
court being dressed down by a judge. He isn't the only one who can't
handle being shown to be in the wrong and has taken it too far.

an idiot.
