The bar is not actually to scale, sorry about that &#8211; it should be thicker, because it contains a <em>lot<\/em> of rebar. The gradients of colour are wifi strength, from a nearby hotspot which is <em>not<\/em> ours. I picked this one because it shows the effect best, but it shows up in imagery of other transmitters as well.<\/p>\n<p><center><img decoding=\"async\" src=\"http:\/\/solarbird.net\/Livejournal\/2015-10\/parabolic-reflector.jpg\"><\/center><\/p>\n<p>Do you see what&#8217;s going on here? The rebar in the retaining wall appears to be acting as a crude <em>parabolic reflector<\/em>. This relatively-hot-spot is showing up in all of the maps, pretty clearly, except for the ones where that area shows up as a shadow of <eM>reduced<\/em> strength. I think those are signals from transmitters from the other side of the wall.<\/p>\n<p>I mean honestly, look at this. Am I wrong? This is <em>so neat<\/em>. And I&#8217;m wondering if this is the cause of some of our other interference problems as well, like possibly even the BBC-World-Service-on-the-house-mains issues.<\/p>\n<p>All sorts of wireless things act <em>very<\/em> strangely here. Even AM\/FM radio. And I&#8217;m starting to wonder if there&#8217;s a way to improve the grounding on the rebar.
