Default Would an attic install work for my situation?

I'm seriously considering parting ways with the cable company, but I'd like to gather input from you smart folks here to see if an attic install would be do-able? Here is the link to my TV Fool.

http://www.tvfool.com/?option=com_wr...e6a4e2eb94e7cd

If you look at the report, I'm only interested in the first 6 stations listed since those are the local channels for my area. The height of the attic install will be about 15 ft. from ground level. The end goal here is to avoid doing a roof install if possible. So wanted to ask if I could get by with an attic install in this case?

Also seeking out advice on the type of antenna I should be looking at if an attic install is possible? Directional? Multi-directional? Yagi? Grid? etc.

Thanks for your time.

Some more pertinent information about my house.

The roofing is shingled with no metal. Also the siding is vinyl, so no metal there either.

I had read that metal roofs and siding would make it harder for signals to penetrate, so wanted to point this out.

A metal roof makes it impossible for any TV signals.

Any roof (other then metal) will drop the available signals by about 1/2. (a tile roof a bit more)

And looking at your TVfool report an attic mount will not work as all the signals are first and second edge, you used 15 feet as a starting elevation for the antenna, try it again but this time try 20 feet, and then keep going by ten foot increments to see if the signals become LOS. (Line Of Sight)

Here is a side view of the first TV channel, the transmitter is on the far left, you are on the far right, the Earth is in the way at 15 feet.

Terryl3,

Appreciate the response. I'm learning a bit more as we go here. I couldn't figure out what that link you provided meant when I looked at it awhile back. But it makes a bit more sense now that you've informed me of it.

I took your TV Fool advice and it looks like LOS comes in for all of the local channels at 50 ft. So it's not a feasible situation. Too bad really, but such is life. If I get creative I could probably place shift a la Sling at a relative who lives in the Omaha area, but that's just not a convenient solution.

But thanks again for your input.

50 feet is not that unusual for some flat land locations, if you have a second story roof it is feasible, even a single story roof makes it workable, but this is not a job for someone that has never raised an antenna higher then 20 feet off the roof.

At 33 to 44 miles a decent sized mid-range antenna would work out fine, it may even work out at 30 to 40 feet, but the problems with some flat locations is that the Earth itself gets in the way the further you get from the TV transmitters, so the higher you can go the better.


Do you have any neighbors close by with a tower or tall mast on the roof?

If so ask them on how the signals are with their setup, then you can duplicate it.

None of my neighbors have antennas. However I do know of a few people who do have them locally installed at their house, but they're in better position of the towers so have no issues picking up stations. Matter of factly, my best friend's place of business has an old school 1960's yagi antenna mounted 20 ft. off the ground on the roof and has LOS to FOX and CW while 1EDGE to NBC, CBS, ABC and PBS, but they're able to pull those channels in without issues. They're located 1 block north and 13 blocks east of my house.

In my situation, I have to contend with Arbor Lodge State Park. It's 3 blocks north and west of my location and sits on a higher elevation than my house. Those towers I'm trying to reach are... you guessed it, North and West of my house.

For those unfamiliar with Arbor Lodge, you might know about the national holiday we celebrate called Arbor Day? So lots and lots of trees. The home of Arbor Day resides 3 blocks away from my house in Nebraska City. Which is why some people in my town are able to successfully pull in those channels. So long as you don't have to contend with Arbor Lodge State Park. And the ones I know who have antennas don't live in the shadows of that park.

I might just buy a 50 ft. telescoping pole and burying it 5-6 ft. into the ground on the west side of the house and installing an antenna, which leaves me 44-45 ft. of LOS to the towers. So I do have options. It depends on how bad I want to cut the cord, I guess?

A 50 ft telescoping mast will require guy wires every 10 foot section, and sinking it in the ground will do nothing to support it.

A mast at the peak of the roof is a better start, what is the highest point of the roof peak?

If 20 feet then a 30 foot mast would work, you will still have to guy it down every 10 feet.

Yes, I'd already factored in the guy tie-downs when I made that post.

However, I talked to my next door neighbor who is still in touch with the original owner of my house. He said it was built in 1962 and he moved out of it in 2010. I'm the 2nd owner. I asked him if he knew if the original owner installed an antenna at any time and he told me he actually helped him install it. He said he remembers it being a medium sized log-periodic antenna, but couldn't remember the brand of it.

Guess where they installed it? The attic!

He said back then they would get 5 stations over-the-air, NBC, ABC, CBS, PBS and WTBS (aka TBS) before it went strictly cable.

Apparently my neighbor also had a log-periodic antenna installed in his attic as well. He said they both quit using antennas around the mid-80s for Cablevision when it first came to the area. I asked him if he still had his log-periodic antenna hanging up there and he said no, he gave it to a relative.

That was an informative chat. My neighbor is 86 years old and has lived in his house for 58 years this year. The original owner of my house is 84 and living in a retirement community in Arizona. He said they lived next door to each other for 48 years. Lots of cool stories there.

First buy a deep fringe rated antenna from a major manufacturer (not cheap Chinese junk advertised as a 150 mile antenna) and try it in your attic. Make sure the antenna type matches the channels you want to receive (VHF-low/VHF-hi/UHF).

If it works, great, if not then you move it outside, no need to go more than 5-10 ft above the roof line for this second try.

You should get something, maybe all you really want with an outside antenna at 20-30 ft AGL.

Maybe add a pre-amp.

That failing you go higher with a telescoping mast on the roof.

Digital TV reception is more of an art than a science, but just a little more.

And so forth, best wishes.

Thanks for the suggestions, Jim.

Just out of curiosity, who are the major manufacturers these days? Off the top I can think of Winegard and Channel Master.

Antennas Direct, Channel Master, RCA and Winegard come to mind.
