The line: "For computers, it's used the de facto standard Mcx cable." is not just bad english, but also probably very POV as there are lots of different cables used for antennas (The link points to a company called MCX Inc!).

## Direct link for Schmitt reference

The reference "Understanding electromagnetic fields and antenna radiation takes (almost) no math", by Ron Schmitt, EDN Magazine, March 2 2000 is linked to a host that is not related to the publisher (very useful article, by the way). Since the article is freely available on the EDN website, shouldn't the link be made to that page? Here is a direct link: http://www.edn.com/article/CA82250.html That page contains a link to the PDF version, which is the same as the one currently linked.

## bandwidth limit

The June 2009 Antennas and Propagation article addresses only magnetic dipole antennas, but the conclusions apply to electric dipoles by the symmetry between electric and magnetic fields. It gives a tighter upper bound for loop antenna band widths. Magnetic materials help by lowering H for a given B.

## Voltage and Current of dipole in quadrature?

What's with the animated gif showing voltage and current out of phase?

In what sense? It's just the normal behaviour of V/I for any sort of transmission line - they're out of phase. Consider the basic derivation from ${\displaystyle Q=CV}$ and ${\displaystyle I=dQ/dt}$, thus: ${\displaystyle I(t)=C{\frac {\mathrm {d} V(t)}{\mathrm {d} t}}}$ When it's a sine wave, then the derivative can be seen as either a cosine, or else the same sine, with a phase shift.

Assuming a proper resistive load at the end, the normal phase difference of V/I in a transmission line is near zero. Where did you read otherwise? As for the antenna, if the amplitudes shown represent the voltage (wrt midpoint I presume) and current along the wire of a resonant dipole, the implication is the feed point is reactive which isn't the case. OTOH if we are being shown field strengths or electric charge, that changes things. The animation is likely a bit too simplistic for encyclopedic use and is likely misleading. It has become wildly popular on the internet because it is a cool graphic, but conveying incorrect information. crcwiki (talk) 21:13, 5 September 2017 (UTC)

## Bloviation

It sure seems the Wikipedia edicts contained in here...

 https://en.wikipedia.org/wiki/Wikipedia:Article_size


...have been utterly ignored for this important article in part due to the copy and paste of other articles within this one. Has anyone even bothered to make this article encyclopedic and not a college text? crcwiki (talk) 14:30, 6 September 2017 (UTC)

This is not a useful observation. Every Wikipedia article contains at least one extra word and one error. Therefore the ultimate Wikipedia article is one word that is spelled wrong. This is the encyclopedia anyone can edit, have at it! -Wtshymanski (talk) 16:46, 6 September 2017 (UTC)
