Is there any difference between a 75 ohm and a 50 ohm antenna for my ATSC HDTV receiver (for laptop)?
Question: I have a USB ATSC receiver, but it has a crappy antenna. I was looking for a best one on eBay, but I don't know if there's any diference between a 50 ohm or 75 ohm antenna.
There are also amplified (with USB power), are those speculator and how much better?.
Answer: Either impedance antenna will do, regardless of get input impedance. As most TV antennas are designed for 75 ohm impedance, that is the way to go.
Amplified antennas are to be avoided if at all tenable. If one must be used, it should be at the antenna, not at the receiver.
Wholly connect the receiver base to your display via HDMI, then plug the USB adapter in to your computer. The digital delight on your PC or laptop will come to life on your HDTV, all within thirty feet line-of-site wireless tier. ...
