Question: What company makes these antennas?
Document: Makes my HDTV worth it. No other antenna, even a powered $100 antenna worked better than this. Looks great and high tech, too.
I've tried several antennas and have been disappointed with all of them. I live in a major city and all of the stations are within 10 miles. This antenna gives me 100% signal strength on all of them.
My building has notoriously bad reception. This antenna was much worse than rabbit ear antennas on both UHF and VHF. I'm thinking only an amplified antenna gives any hope of better reception and then still not assured.
I don't really like this thing. I got my hopes up that I would get lots of channels so I ordered it with one day shipping. I have had other antennas rca one looked like bat wings and that got plenty of channels.
I think that this inexpensive antenna is the best around. I've paid more money for crappy antennas that wound up in the garbage. I'm thinking of purchasing another one as a backup. Don't let the price and the look fool you. This baby gets the job done. Keep in mind UHF only!
Okay, thought I'd really see if this thing made a difference so I plugged it in by itself (I have 2 antennas on the roof) and it basically said "Stations? What stations?" couldn't find a single station in my area. So just for grins I plugged in a set of old rabbit ears...guess what? They found all the stations, all in all very disappointing.
I've owned a total of three HDTV antennas. The other two were different designs but similarly priced to this model. The other two had telescoping ears that eventually broke or bent due to me having to adjust them to improve the signal. This model doesn't have telescoping ears to break, which is awesome. The antenna itself is actually just a heavy stock of coated paper.
ALL indoor table-top or wall mount antennas have limited effectiveness. Purpose-designed antennas such as this one are better than rabbit ears, but obstacles and your location relative to the TV stations will limit reception from ANY antenna. Don't blame the antenna if reception is not up to your expectations. Most any attic mount or roof mount directional antenna will bring in more stations than an indoor antennas.
The area where I wanted to use the Artec antenna is awash in electromagnetic interference from six different wireless devices, including a wireless router. I've tried other antennas in the same room, with the same results, poor or no signal. I'm only answering the survey to make this point. The purchase, delivery, return and refund was seamless. No problem at any point of the process. I would do business with seller, on this website, again without hesitation.
This is another of the cheap little antennas on the market that work &#34;so so&#34;.I had to turn it different directions to pick up different stations.I finally went back to my old &#34;home made&#34; antenna, and was able to pick up the stations I wanted without effort.I recommend this to folks that don't want to spend a lot of money for an outside antenna, or don'/won't build their own from scratch.
Answer: i do not own the antenna, it wouldn't work because we live in vally with lots of trees. i did not know who makes them, i sold the antenna!
