DIY HDTV Antenna Sticks To Your Window without Blocking the View

This DIY fractal-based HDTV antenna is cheap, easy to craft, and can be stuck unobtrusively on your window for better signal gains.

Courtesy of HTPC-DIY, this simple build uses aluminum foil, a printed fractal pattern, clear plastic, and some basic hardware to create a lightweight and transparent antenna you can affix to a window without significantly blocking light from entering the window. Hit up the link below for the full build details as well as designs for other DIY antennas.

    “to create a lightweight and transparent antenna”

    Apparently you guys have a different definition of “transparent” than …. well…. everyone else.

    I’m pretty sure that would not meet the WAF.

    Nice idea but most HOAs, apartment managements, etc. would raise a ruction over something like that.

    These articles are always about multi or omni directional antennas. These don’t work for me, whether home made or commercial. Why are there no instructions for directional antennas?

    I live in the downtown core on the second floor, right at the height of all the wiring of both electric supply and the streetcars (Toronto). So even though I can practically spit on the CN Tower (most channels broadcast off this), I can’t get even the strongest local signal with omnidirectional.

    One other thing you probably need know (if you don’t already) is that in America (USA), all ATSC terrestrial over the air (OTA) broadcasts are now in the UHF spectrum. You do not need a VHF antenna to receive any of the newer “digital” OTA channels. In fact, the VHF spectrum for OTA television is no longer used and no longer allowed by the F.C.C. That’s not due to the very poor NTSC standards but because the VHF bandwidth needed to be freed up for other things (or so “they” claim).

    Point is, if you already have a UHF antenna it will probably work just fine. But you will almost certainly need to put it in a good location (and maybe even have to amplify the signal).

    BTW, Cable service in USA doesn’t even use ATSC (despite some people claiming otherwise). Cable uses the QAM standards which requires yet another tuner. Most channels over cable are also encrypted so that a cable provider can charge extra for additional channels. They might also charge extra for additional equipment in order to receive these “digital” channels in all their “HD” glory too.

    The thing that irks me is that some people actually pay for this “HD” service from their cable provider but then get a cable box or something that just mashes it all down to a crumby NTSC signal that is only receivable over VHF channel 3 or 4 on the actual television. Talk about being fleeced! Even worse is that most cable companies won’t even tell you that local programming is being transmitted over cable in full digital HD (thanks to a F.C.C. mandate) that is receivable without anything other than a a”clear” QAM tuner (IE, no encryption).

    It appears the Trolls have arrived to nag this post to death. I personally think it looks cool and would hope that it works!

    Thanks for the post :)

    “I’m pretty sure that would not meet the WAF.”

    I don’t know. Many of the pins I got on pinterest were from women.

    The design is small and thin so if you mount it on a window it will be hidden by window treatments. If you take more care gluing it together than I did you won’t have the smudges. If you mount it on a wall you can hide it behind a picture or mirror. Also no pointy wires for kids to poke themselves with.

    I’ve tried everything this side of a tower, but every vehicle still blocks the signals.
