  1. I've googled the heck out of it & am wondering if its possible to make a tv antennae by simply using a 10 foot piece of Coaxial_Cable.

    I GOT AN ANTENNAE (ota) FROM A fRIEND & IT HAS THE WEBSITE https://winegard.com/ on it, I went to it but cannot find anything to do with it , pic in next post,hopefully
    #EDIT, correct website..

    It requires a USB power cord but I can't find it on their website.

    That cable is shielded and thus should NEVER pickup signal(s) of any kind. They are used to move the signal induced at the antenna to the detector circuit with minimal losses.

    Ok, understood. BUT, if ALL covering(s) were removed, would it then be UN shielded? Just curious & thank you :)

    Thank you for the link but it still don't show me a clear picture of the power source cord.:confused:

    Guess you could do that, but that's a lot of work. OTA signals are best received outside in an unobstructed area - - above the roof line. Regardless, you need to support the free, unattached end and the overall length should ideally be a multiple of the wavelength. IMO, stick with an over-the-counter device.

    "OTA signala are best received outside in an unobstructed area?? I've used rabbit ears, but thanks for your input :)

    Super. I'm in rolling hills terrain and even roof top antennae's don't pull sufficient signal for a tolerable picture.

    Clarification, I should of said before cable, people used rabbit ears v-shaped-rabbit-ears.JPG

    Oh yeah ... '50s technology. Even in Los Angeles (line of sight to local TV towers), most went to roof-tops rather quickly.

    @jobeard would the antennae from a laptop work on a tv ?

    Learningmypc - I think this is yet again an issue where you are presenting a problem and wanting a solution where the easiest solution is to avoid your 'problem' to begin with. If you were given an antenna that doesn't work, then ok, it doesn't work, move on. You can't change physics. Jobeard mentioned rabbit ears - you don't need a fancy antenna to pick up a signal, you need an antenna that CAN pick up a signal, some are better than others at picking up specific frequencies. That is what the "HD" ones do, they are optimized. THEN you need to be able to decode/display that signal. You can optimize the heck out of something and that does no good at all if you don't have anything that can decode or play back that signal.

    I'm making a lot of assumptions here, because we are now 18 posts in and you haven't said you got it working, but you can't just connect an antenna to a computer and get TV. It has to be decoded, especially now in this 'digital' tv age. Something has to decode it. TVs for decades had 'modulators' in them to decode, but that has stopped in recent years. This stuff isn't magic man, there was lots of science/engineering/knowledge/skill/learning/building blocks behind it. If you don't build that into the wiring/chipsets of what you are connecting that coax cable into, there is no way for it to do anything meaningful for you.

    I understand & no, I haven't got it taken care of yet. I will wait till my landlady finds the power cord to the antennae she gave me. Thank you :)

    @learninmypc
    Before going digital, ALL signals were AM or FM
    Either way, there's circuit called the "detector" to remove the RF, keep the "intelligent information" and pass that into the audio/video system.

    Digital has a similar flow through the hardware, but the "detector" is now more like a decryption device, decoding the zeros&ones.

    The function of any antennae is to send "signals" to the "detector" and at high frequencies, the antennae must be built (aka tuned) to the frequency band desired

    Thank you. Not as easy as I thought it would/could/might be. Youtube made it look so easy Geeesh :)

    Here's a site to help in antenna selection http://www.antennaweb.org/Address

    Use your ZIP code and it responds with the Stations available over the air, distance from you and a list of possible antennaes.

    Thank you. My landlady gets back next week so II'll be able to solve this headache then. :)

    I'm late to the party, but in the past I've done exactly what you're asking with success.. You have to strip the shielding off of the coaxial cable to expose the copper wire, I've done it with about a 1 foot circle and gotten a lot of channels. Assuming you have the tuner in your TV.. it's not going to pick up as many as a normal antenna of course.
