Specification of this Digital TV Antena Outdoor :
What Purchaser said about this Antenna ?
This Antenna Digital very Excellent for Outdoor use. You assembled the antenna by hand using the enclosed directions, easy
no tools needed. Powered and tested the rotation/motor of the antenna
in the house, worked as expected (didn’t use the remote as I didn’t have
batteries, used the dock). Grabbed my ladder and tools with additional
wood screws and washers as the package only contained 2 wood screws
(not enough if you ask me). Climbed on to my roof and mounted the
bracket on the side of my chimney tunnel exit than mounted the assembled
antenna with pole. Ran the antenna’s coaxial cable down the side of my
house and used a flat coaxial jumper cable to get it through my window
seal into my house as I did not want to drill through my wall. Once I
plugged in a second coaxial from the window flat jumper cable inside my
house to the antenna power box and a third coaxial cable from the power
box to my TV, I was in business... I troubleshooted the antenna rotation
using our favorite channel that used to be fuzzy and studdered until I
got great reception. The great news... once our favorite channel was
in perfect reception, I used the settings on my TV to auto save all
view able channels and now I have a TOTAL OF 54 CHANNELS (we live in
Belton MO) that my family and I can watch!! That’s a win if you ask me.
We had under 10 channels that stuttered before with our typical indoor
antenna. Now to see how far it holds up and see how well it works
during bad weather like rain and snow, not so sure if the material would
hold up in Arizona sun but will be willing to try when we move back.
