Saw a flatwave Winegard antenna similar to what you were showing at the start of this thread. It looks like it has the amp in your picture. See at the bottom of: http://www.winegard.com/flatwave?q=offair -- Also saw it on Amazon ( https://www.amazon.com/dp/B00BN5Z2WM/?tag=httpwwwtechsp-20 ). Walmart, Home Depot, Staples, etc. sell this antenna. You could check it at one of the stores to see what is the adapter output voltage. It may be just the a run of the mill USB adapter. BTW, it gets a very good rating and reviews.Mine is about 18 inches long, haven't got ALL the matallic covering off yet thou.
See my first reply just above. I found some more info. It looks like the adapter output is 5 volts. See: http://www.winegard.com/amplifiers -- I assume the one you need uses the same adapter.It requires a USB power cord but I can't find it on their website.
What was the output voltage going into the USB cord (should be on the adapter you plugged into)? Some output voltages are less than 5VDC and it may require that much voltage to drive the amplifier. If the amplifier is shot, you may have to contact Winegard for a replacement.This is the Winegard contact page: http://www.winegard.com/consumer-contacts . It may be worth a shot to contact them.Ok, I found a USB cord in my junk box that fits, but when I plugged it in, & rescanned for tv stations, nothing. Thanks for the link, will continue looking.
That should work (5 VDC). It may be the amplifier is shot. Maybe a power surge took it out and that is why your friend gave it to you. Check the Winegard site: http://www.winegard.com/hdtv-indoor-antennas?q=offair . The "amped" antenna is supposed to be good according to reviews I read - 50 mile range. The non-amp antenna is supposed to be good up to 35 mile range. You can pick another up at Walmart, Home Depot, etc. Check out prices on the internet, Amazon is not always the cheapest on a lot of things like many people believe. Walmart sells it for $55.53 (previous time I checked, Amazon wanted $60 and I see they just dropped their price to match Walmart's price).
Thank you, situation was taken care of months ago.The cheapest antenna you can make is probably a paper clip straightened out and stuck right into that center hole. The signal is going to be pretty crappy, but with the digital TV stuff, if you are getting a strong enough signal you will get a clear picture.
