Thinking of cordcutting? Even if you can't build a speaker, you can build an antenna.

If you are thinking about cord cutting but want to get local channels (in HD), try making your own antenna.  You can get an idea which channels you could see with sites like http://www.tvfool.com/ or https://www.antennaweb.org/

 

The only part I didnt have readily laying around was the Balun transformer.  There are ways to make your own Balun too, but I just bought mine from Ebay (slow boat from china method).

Here's a link to the site I used to build mine, it's a wayback machine link as the site is no longer live:

Single Bay Gray-Hoverman Antenna (SBGH)

Parts List:
2 - 4 foot 1x4 pine boards
6 - 3/4" Screws
6 - Finish Washers
10 - 2" Wood Screws
2 - 5' lengths of 14 gauge wire
1 - Balun - This transformer is needed to adapt the antenna's signal to your T.V.'s coax input. It is available from many sources. 

Here's what mine looks like (no reflector - easier and I had channels on both sides of antenna), let me know if you have any questions or if you plan to build one.

I've gotten more channels with this than with an amplified rabbit ears style antenna you get at the store.  I then hook this up to a Silcondust tuner and Plex for my DVR, I can share more on that too.

Enjoy!

@imcokeman I wish I didn't just go buy an external antenna.  I would have definitely tried this out.  I needed one for the Super Bowl 🙂  What a great idea!

If you have any channels you are missing, do it for fun, if you have everything perfect than no need to play. At least now it's low risk, you can just order the balun on the slow boat, or make a coax one if you feel like really doing it all yourself.  

This part I haven't done, but I hear it can really help if you have one fringe station to ensure maximum signal transfer. You solder the shielding together and make an extra loop of cable to balance the unbalanced antenna here's a site with a diagram:

For example if you wanted channel uhf channel 35 it is ~599mhz you can put that in the calculator and the loop is then 6.5 inches.

Antenna web should show the actual channel number (digital number may be different) and you can look the MHz up here:

Thankfully, I am getting all my channels.  Funny thing is, I live much further away from the channels here in Tennessee, yet get  all my channels.  They also are coming in much clearer.  Of course, in PA, I beleive there were some hills in the way, that severely impacted my range.

@123toid

PA is an interesting state for radio/TV signals. There are places where you can pick up for over 100 miles, and then only a short trip away reception is crap. Also might have something to do with the underlying geology. Lots of iron below. 

One thing I miss from the old analog days was the thrill of adjusting the set "just so" to pick up that distant station and be able to see and hear it, even through the snow. TV DXing really was a thing back then. I even know how to use tin foil. 😁
