Over the air TV depends on where you are some areas any old rabbit ears work well, other areas require a VERY good antenna. I'm in Phoenix, Arizona and I use this: https://www.amazon.com/RCA-Multi-Dir...igital-Indoor- Antenna/dp/B0027FZQ1E/ref=sr_1_18?ie=UTF8&qid=1547596238&sr=8- 18&keywords=rca+tv+antenna+indoor OR https://tinyurl.com/ybret529 This allows me to get all the local OTA channels but I got only about 4 or 5 before I moved so who knows? I'd find an old rabbit ears and see what channels you can get, good luck! The best antennas are still the single-direction ones like the DB2E. I use one of those on the bottom floor of my condo and get great reception but got a Flex antenna from AntennasDirect which is multidirectional and gets signals up to 80+ miles. I'd recommend that one simply because of the multidirectional aspect but it's pricey. |

I live in Montreal and every Canadian station is on UHF so they're particularly easy to get wherever you live on the island or outside. Even the American channels are fairly easy to get as long as you know where to point the antenna. However, ABC out of Burlington, Vermont which broadcasts four stations from the same antenna (ABC, Quest, Laff and Grit) uses VHF-Lo which requires an additional attachment to most antennas being sold or one of those old, metallic antennas pointed in the right direction. |

I have a brother in NH who I think still uses a giant rooftop antenna with a motor, to get Providence, VT, or Canada. They don't have cable. (Or cellphone signals.) Which seems to be much more common than most urban people realize. We used to have one VHF station in Boston, but now I think they're all UHF. Though I don't really know the reason. Maybe that's a case for finding old rabbit ears that handle both. We have two TVs. One's using the newer "plate" style UHF antenna. One uses old rabbit ears with a UHF ring. Both pick up about 45 stations. Though I should note that at least half of those are Spanish, religious, shopping, or spend most of their time showing commercials for vaginal mesh implant lawsuits. I've also seen ads on TV for these new antennae. I found it somewhat comical. In the few short years that TV antennae have become rare, apparently it's developed that most people don't know what they are. So now they're marketed as an amazing new technology to be sold to cordcutters. |

In this day and age of leftist propaganda and repulsive demands that the public embrace not only homosexuality but transsexuality and pedophilia (look up Desmond is Amazing), it's in everyone's benefit to just cut the cord and limit how much television they watch. It's literally impossible to watch an awards show or even a sitcom without someone on screen virtue signaling about how everyone must accept open borders, 5 year-old boys who think they're little girls and grown men using the women's washroom because they claim to be women. It's sickening and the disgust should not be limited to Christians. Anyone with any kind of moral fibre should reject this trash wholeheartedly and demand that these monsters be prosecuted. |

So now they're marketed as an amazing new technology to be sold to cordcutters. In some countries, your government cares enough to provide web information on the topic. I suppose this is for countries where more people are rural or outside the range a lot of people here would be dealing with. https://www.acma.gov.au/Citizen/TV-R...antenna-system I tried to find coverage maps for TV in Canada, and Google wasn't coughing them up (they used to be available). I wanted a map so I could make fun of our coverage. We seem to care little on the topic now. During the digital transition, our government provided $0 to TV stations to pay for new equipment. And the coverage we have today reflects that. That's also why they allowed a station with a channel 6 analog transmitter, to transition to DTV using the same channel 6 transmitter. ******* The information I can find on those plastic (fractal) antenna panels suggest an urban user would likely be pleased with one, and see enough performance to conclude "it works". Without it performing miracles for reception. It would make a decent placebo (i.e. just as good as the rabbit ears I slap on my distribution here in the house). You need to have some sort of exposed wire, as just leaving the 75 ohm coaxial connector on the TV set open to the air, won't couple in enough signal. In terms of material cost, you can see these fractal samples are cheap to make. To me, it seems unlikely such a design would match 75 ohms on its own. Maybe the balanced to unbalanced transformer (balun) is located elsewhere. The impedance of antennas even changes with frequency, which means an "exact" match at one frequency is a less than exact match at others. TV is pretty tolerant of that mismatch (the match doesn't have to be perfect). https://i.postimg.cc/SKJg5Fjz/cheap-...a-business.jpg They could also put the fractal panel inside the TV set itself, but that wouldn't be flexible enough in terms of positioning. There could be an OTA TV station at an inconvenient location, that would require rotating the TV set in the living room for best results. I don't think TV buyers would like that. But making people pay for a panel separately, is also naughty. As the antenna panel could be made for $5 and thrown into the box as an accessory. Paul |

Â*Â* Paul Back in the 1960 to 1968 period I installed a 25 foot guyed mast on the peak of my 30 foot 2 1/2 story house, T the top of which I installed a Channel Master rotator and a Channel Master 12 element Yagi antennae with which I was able to receive 5 VHF channels, The furthest being Pembina, North Dakota, 75 miles away, a 4 channel amplifier splitter fed 3 TV sets, one of which was a Heathkit 21 inch colour set which I assembled. Back then the cabling was all 300 ohm twin lead, later upgraded to 75 ohm RG59 Coax. The Whole rooftop installation was a major 1 man only job as I had no one to help, the roof was 45 degree pitch and wooden shingles, kinda scary at times. Rene |

There is a channel 7 near here (which does actually broadcast on channel 7, VHF-Hi), and rabbit ears do work for that if you're close enough to the transmitter. BTW, most rabbit ears have adjustable length. Short works best for higher channels and long for lower channels. 7 is near the middle. -- Mark Lloyd http://notstupid.us/ "Horrible Bug Encountered.
