High Definition, Old School Methods

This is a coax cable, you split and then connect some piece of metal to, to form what's called a dipole ... basically a metal thingy that can catch waves.

I'd like to start this story by saying that my knowledge of electronics, electro-magnetism and antennas are next to nil - like most people, I have a vague notion that waves send signals through cables, through the air, satellites and so forth ... but that's about it. I recently bought an HDTV, replacing my 10-year-old analog television, which had started to produce high-pitch noises after being on for a while. This is the story of how I (and many others) have gone back to getting TV channels off the air, rather through the regular cable or satellite provider.

While this story might seem somewhat dry to some, to me, it represents a sort of ham-radio type of democracy that I didn't think could apply to the airwaves - while the Internet definitely counts as a democratic technology (in some countries), it has yet to replace the television in terms of ease and accessibility.

It's free, but not for you.

Essentially for years, if not decades, many people have preferred to slap on a pair of rabbit ears to their TV set, rather than pay for cable for various reasons - as expected, unless you have very good rabbit ears or a fancy antenna parked on your roof, reception really varies depending on where you live. Let's face the facts however, cable programming is by and large forgettable; there's always a few channels that are good but you have to pay a premium price to get them.

The same unfortunate truth exists for digital television - where the price for such channels via cable or satellite are extremely expensive (60$+ a month) - now here's the punchline or the part where digital subscribers get punched in the gut: The majority of the digital signals cable companies get are taken off air and then re-compressed to a lower quality (so they can dish out more of it). So essentially, like bottled water, you are being sold something that is already free ...

It would make sense, when you look at those large antennas, it's really just more metal...taking up more space...- you could try adding a reflector too like the one in the photo of the shoebox.

That's a great story Lu.

I wonder if I can increase the range of my WIFI antenna by using wire and a coat hook?

I know you can buy a larger antenna for your WIFI router for $60. But for $60 I could buy another router.
