Loading coils for power transmission systems? Can anyone substantiate this statement? While capacitors are installed for power factor correction, I am unaware of the use of coils in power distribution. LorenzoB 04:43, 13 January 2007 (UTC)
Does anyone have any images of this because I want to know what they look like. —Preceding unsigned comment added by Komomisp ( talk • contribs) 19:19, 7 September 2008 (UTC)
This article does a good job of describing how a loading coil is used, but not what it IS, other than to say "it's a coil", which is obvious from the name. The picture makes the reader think of a transformer.
Wikipedia articles can't be written for people who already understand these things.
I barely have time to write this note, but somebody say that it's a electricity-conducting coil (as opposed to a coil of rope), what it's wrapped around (plastic), HOW it increases inductance, and why inductance is a good thing. And take a photo of one they might have seen on a cable, not just a schematic. HelviticaBold 00:18, 17 March 2012 (UTC)
This is the type of instrument you would need to recharge car batteries, along with a pulsating current to create a fluctuating current of some sort or current which goes one direct ie direct current flow. — Preceding unsigned comment added by Mvdc1980 ( talk • contribs) 16:28, 10 May 2014 (UTC)
"A loading coil is not a transformer to provide coupling to another other circuit."
If the page weren't "protected," I'd have made the simple edit, myself. Instead, I should suggest another proofreading by whomever "protected" the page. 75.110.100.120 ( talk) 17:55, 13 June 2015 (UTC)

The second sentence in this article:
A loading coil is not a transformer to provide coupling to another other circuit.
Should be changed to
A loading coil is not a transformer and it doesn't provide coupling to another circuit.
Because: 1) "another other" is grammatically incorrect 2) The current wording is ambiguous, as it isn't clear whether the loading coil is a transformer that doesn't provide coupling, or isn't a transformer but provides coupling. Rewording it in the stated way removes this ambiguity.
Note: The word "transformer" could be linked to the Wikipedia page on transformers. 167.220.196.248 ( talk) 12:20, 7 April 2016 (UTC)

I would like that you add loading coils to the category 'Serbian inventions' as they were invented by Mihajlo Pupin. Thank you. Jwred ( talk) 00:59, 9 April 2016 (UTC)

The sentence is unnecessary and I would recommend its deletion: "A loading coil is not a transformer as it does not provide coupling to another circuit."
Coils are common elements in nearly all manner of electrical and electronic circuits. Their use in transformers is a special case. — Preceding unsigned comment added by Rico402 ( talk • contribs)
@ Kbrose: I propose that this article be standardised on British English. I wrote the great majority of this article and I have been using British English (as shown by "favour" for instance). I realise that the word "center" appears in the article (in an image caption for instance) but this is a comparatively recent addition post-dating my work. The subject is by no means an exclusively American one; it is international, and the earliest proponent of loading was the British engineer Oliver Heaviside.

@ Chetvorno: pinging you because you seem to be knowledgable in this area. Do you agree with the removal of the lead picture in this edit? The reason given is that it is a phasing coil, not a loading coil. As a photograph, it is a nice image and it's a shame if we can't use it.
If you agree, why is the image in the antenna section ok and the lead one is not? As I understand it, a phasing coil joins two sections of electrically short antenna in phase, effectively forming an antenna array. Typically, the two sections are the same length. Neither of the images look like they meet this requirement so the identification as a phasing coil needs justifying. Spinning Spark 17:00, 16 October 2020 (UTC)
@ Gah4: who also might know something about antennas. Spinning Spark 17:36, 16 October 2020 (UTC)
Frequency of operation matters, typically loading coils are only necessary on mobile antennas operating on lower frequencies (< 100 MHz) where wavelength makes full size antennas like a 1/4 wave whip impractical. The cellular antenna in the removed image operates around 860 MHz and the phasing coil does not function as a loading coil despite the mechanical similarity. The second image of a citizens band (27 MHz) antenna is a good example of a loading coil used to make the physical length of the antenna shorter than the electrical length.
The coil in the cellular antenna is not a loading coil because it is not used to make the antenna physically smaller. The cellular antenna is a full size 1/4 wave antenna below the coil and a full size 5/8 wave antenna above the coil. The only function of the coil is to feed the two antenna elements in phase.
