Hi there...
If you have all your antenna towers pointing in one direction, here is a great affordable OTA antenna.
Its replaced an old 15 year old Phillips Mant 940 antenna I had that finally succumbed to the weather elements here in FL. When I performed autopsy on the antenna it was an unusual design but filled with water... anytime you let the smoke out of an electrical device or let water in its not a good thing. The unusual design was it had two parallel length metal pipes about 8 inches long and about 1.5 inches apart and a smaller one about 5 inches long about 3 inches away from the other pair. I suspect it was a tuned pair with the active element the shorter one is my wild guess.
Anyway after the demise, I went and searched of course in amazon and found this design:
www.amazon.com/gp/product/B073V3J5MQ/ref=od_aui_detailpages00?ie=UTF8&psc=1
The design is based on "log-periodic antenna (LP) or (LPA), also known as a log-periodic array or log-periodic aerial, which is a multi-element, directional, antenna designed to operate over a wide band of frequencies" (per wikipedia). So its a good solid design basis meeting the requirements of a directional antenna for the UHF wide range of frequencies.
Now this is very directional, so if you have tv towers from different orientations it wont really work well and you may need to get a couple of them and use Lens instructions on combining multiple antennas on his blog at www.hdtvprimer.com/ANTENNAS/ganging.html OR find a good omnidirectional antenna.
I got 68 channels from Orlando FL (the central FL antenna farm is located east of Orlando in the Bithlo / Christmas area of FL) so one orientation works great for me even with being 45 miles away.
So we will see if the antenna holds up, the price on the antenna can vary, when I bought the price was approx $14 and after a bit the price went up to $18 and now its back to $14.
On amazon site I do have a review with picture of my mounting using old satellite dish bracket. The higher you get the antenna up of course the better the chances of signal.
