Can an iPhone placed inside a water tank receive wireless LAN signals?

[QUOTE="Baluncore, post: 6899953, member: 447632"] The size of an efficient antenna is related to the wavelength. Raising the frequency, to shorter wavelength bands, will reduce antenna size. Most mobile phones do not need inconvenient external antennas. Likewise, the antennas used for Wi-Fi now can be entirely inside the box, but people want to buy "wireless things" with a visible antenna. What is it with tornados of SiC ? Hanging a 377 ohm "space cloth" curtain would absorb more RF energy than a rotating cloud of SiC. [URL]https://en.wikipedia.org/wiki/Space_cloth[/URL] If you want to stop Wi-Fi you will need to enclose the volume with a double-walled conductive sheet, having no hole diameter, or slot length, greater than about 1 cm.
