Not yet. And I see a lot of bad reviews... Of course, it will only receive "OTA" broadcasts, just like any "outdoor" antenna. It won't receive cable channels, etc.

I'd be skeptical... it might be... [smilie=042.gif]

Just remember that no one needs a "digital" antenna. No such thing. Don't let them fool you.

All radio/tv/ham radio/ etc signals thru the air are analog signals. Always have been, always will be.

If you want to watch TV for free, just get a decent multi-element antenna (Yagi), and maybe a good amplifier to go with it.

I am about 60 miles between Tally, G Ville, and JAX. I use a $70 tv antenna, with a $50 amplifier. I can rotate it by hand (armstrong method) to point wherever. I stay on the Tally stations, and get a handful that keeps me amused. No monthly bills.

In our area, there's nothing available over the air waves.
To avoid cable tv still requires an internet connection.
Lots of the tv show episodes can be seen at the network host web sites.
The cost of internet service is only a fraction of tv cable.

That will change soon.

Not sure about the actual brand/model in the OP, but have tried similar ones. I imagine most are the same chinese crap just re-branded.

I've tried a few eBay type powered/amplified/motorized HDTV antenna units, most were trash.

I've found so far with a traditional "old school" UHF/VHF Yagi type antenna and a half-decent amplifier that those seem to give decent results. I'm in Spring Hill and get approx 60 channels when antenna is properly positioned (towards Tampa). Used the old Dish/DirectTv wiring for it, split to 4 rooms of the house and still get solid signal throughout, despite splitting. The one run, is somewhat long and has a little bit of loss which was to be expected.

I don't know OP's situation (Renting? Location, HOA etc) but unless you're quite close to the stations those little ones will be disappointing. FWIW I found my antenna up at the curb for trash pickup, they are not hard to find. A craigslist WTB or similar should find you something affordable.

We refuse to pay cable here as well. I'd rather not pay for a service where I'll only watch maybe 3% of the channels I pay for. Netflix/Hulu/OTA covers it pretty well for us.

Antennaweb.org is pretty handy, it will give you a decent idea of where to aim your antenna as well, and give a rough idea of what could be picked up OTA from your zip/address.

Norinco, every time you split the signal you lose half the power (3dB) in that line. Correct about the line loss on long runs.
You can do the math and see where you might need a +3dB or +6dB gain antenna.

Amplifiers make up for that. I’m using one now. It really works. GARY.

Without the amplifier I get about 20% of what I would If I were using it. Mines a two piece, one somewhat near the mast, and the other part (powered, injector?) is just before it hits the splitter.

I would say a half-decent amp/preamp/booster is pretty much required unless your'e close enough to piss on the TV station's tower.

I bought an amplified indoor antenna at Target, trying to get some air broadcast for a TV without a cable box. It got nothing, probably die to concrete block walls, then heated up and started smoking!
Got ROKU instead. Screw "Live" broadcasting - there's very little worth while and I record most everything anyway.

Not true. TV stations have both analog and digital broadcasts.
The digital channel carries a 19.39-megabit-per-second stream of digital data that your digital TV receives and decodes. That band width can be used for 1 station or sub stations depending on how many sub stations the broadcaster has. My local NBC affiliate has 4, 5.1, 5.2, 5.3 and 5.4 that my tv recieves, decodes and displays.

Analog transmission can not carry more than 1 video composite (RGB) signal with an audio signal.

Just because it goes out over the air doesn't mean it's analog.

^ Regardless as to how it works, an ancient aerial antenna will still receive the signals. I think he was saying that more to emphasize that there is no need for a unit marketed as a "digital" or "HDTV" antenna. Whether analog or digital or whatever, they are still broadcast on UHF/VHF.

Thanks guys. My post was not about loosing the cable, rather getting signal with power outage from a storm.
HOAs can no longer stop you, that's been settled in court. l might mount in attic only because of storms.
I did it this way years ago and with the amp it works fine.
With regard to cable cutting, I do not have a computer in the same room as the ONE TV I have.
I'll have to look into running a line from my mimi Mac up and over the the TV, maybe using Apple TV or something.

Yes, it is true, all broadcasts are analog, sine wave based.

"Not true. TV stations have both analog and digital broadcasts.
The digital channel carries a 19.39-megabit-per-second stream of digital data that your digital TV receives and decodes. "

A "digital stream/TV" is just a modulated sine wave. Often the sine wave is phase shifted to represent a different symbol, or series of bits. This kind of phase modulation results in nice, smooth transitions from one phase to the next, which results in a narrow RF bandwidth, which you can see on a spectrum analyzer.

A true digital signal has sharp edges where it transitions from a 1 to a 0, and vice versa. These sharp edges are the result of summing large numbers of odd harmonic sine waves, which result in a square wave, with very large bandwidth, which is very wasteful of our limited RF spectrum.

You’re talking my language, now, Dave.
The RF spectrum allotment is about maxed-out, and expanding into super-high frequencies which are reserved mostly for space and surveillance programs. Will be interesting to see how high it will go.
