Question 1

how many miles away is signal?

Accepted Answer

Most of the TV stations are approx. 40 miles away. The interesting thing about this antenna is: It worked fairly well inside the house, so I thought it would work much better on the roof. It did not work half as well. I next tried it by a window that was facing TV stations and it worked very well, however, when I mounted it outside that window and ran the coax up through the eave and through the attic and down to the TV, it received all the channels as before except NBC. 
Finally, I pulled some of the coax back toward the Flat Wave and formed a loop behind it and got ch. 11 NBC. It is a strange duck but it works.

Question 2

Can this antenna be used for multiple HDTV?

Accepted Answer

Yes, but the signal is reduced for each additional tv. If you get a fairly strong signal, it may work fine. A peculiar note: I first tried the flat wave in side, just behind the TV and got fairly good results. Then I put it on the roof and reception was terrible. Next, I put it in the window facing the direction of TV stations and it worked great, so, I mounted it just outside of the window. I formed the coax into  a 9 inch loop behind the antenna and it worked even better. Weird!

Question 3

what about install ?

Accepted Answer

The install is very easy, mine was complete from start to finish in about an hour.  A coaxial fitting install kit is extremely helpful, and a signal strength locator is helpful but not by any means necessary.  You will need enough coaxial cable to route to each TV.

Question 4

what items are in  the box?

Accepted Answer

Included is the antenna, the mounting bracket that attaches the antenna to the mounting pipe/tube, the mounting pipe/tube, and the wall bracket that the mounting pipe attaches to.  The hardware (bolts & nuts) are included to assemble those pieces.  There is the power adapter with 3' cord & the amplifier head.  There is no hardware (screws or lag bolts) to attach the wall mount to your building/base or coax (RG6) cable.  This info is also listed on the Winegard website.

Question 5

We have a metal roof on our house, does anyone know if that will affect the signal in the attic?

Accepted Answer

I don't have a metal roof and reception was good but I thought it would be much better mounted on the roof. When I tried it on the roof, reception was worse rather than better. I eventually mounted it to the wall just outside of the kitchen window and reception is great.
 To answer your question, you probably would get very weak or no signal in the attic. Asphalt shingle roofing reduces signal 20 -40% according to antenna experts.

Question 6

Has anyone attempted to connect this antenna to an existing coax network? I'm interested in doing so, but not sure if the amplifier that comes with this antenna is strong enough to push through a splitter and to multiple TV's.

Accepted Answer

No, I'm not using a splitter because I'm 62 miles from the transmitters, at a "weak-moderate" signal strength location, per the FCC. Even still, the reception on only 1 out of 14 channels occasionally fades-out. The other 13 are pretty solid. But I'm sure my reception would suffer if I split the signal to another TV.

There's no question you can split the flatwave's output, as long as the broadcast signal coming into the antenna is adequate. The instruction sheet mentions using a splitter.  Check out the signal strength for your address on the FCC's website.  I've also gotten replies to questions via email from Winegard's site in a day or two. You may want to ask them about your particular situation.
