    a no go on channels 3.1 to 15.1 with indoor antenna

    FIRST POST

    hello all,

    we recently decided to drop direct tv b/c of the dispute and they were jipping us out of 17 other (major) channels we were paying for. i picked up a flat indoor antenna and hooked it up. we live in the city limits and to my surprise we receive 16 channels from time to time. i am having an issue getting 2 or 3 channels that are close and have strong signals according to tv fool and antenna web. they run in the number range of 3-14. they broadcast NBC and CBS which would be nice to get. here's the skinny of it:

    the antenna is a couple feet away from our tv.....samsung flat panel
    its also near a window
    we channels 15.1 through 62.3 with exclusions of course....2 ABC channels, 3 PBS, 2 FOX(sometimes and not that great),2 ION, and qubo
    we are missing NBC and CBS, both which are plenty close and strong
    the antenna is a tri quest(very cheap i know) and states on the box it gets vhf/uhf

    this is the tv fool result

    TV Fool


    i tried a small RCA indoor rabbit ear and only got 2 channels as well an RCA outdoor that didnt pull in anything at all.

    i may be missing some info but these are all the details i can think of right now

    any help is appreciated

    Redo the TVFool with your home address (we wont be able to see it, but it will provide better results). Though most likely you will need to use a small outdoor antenna indoors if an indoor antenna isnt cutting it (or even in your attic if possible and isnt tin roof or foil-backed). Best place to have the aerial would be outdoors of course.

    TV Fool

    i actually tried this rca antenna inside and outside but still didnt get anything
    RCA Outdoor Digital Video Broadcast Terrestrial with Amplified Antenna: TV & Video : Walmart.com

    would the indoor that i have do any better in the attic? its not metal or foil backed. just a sure fire pain in the arse to get up into. my father in law lives in a close by neighborhood with similar characteristics and more trees. he managed to get 22 channels with the RCA flat indoor.

    what are the most important characteristics to look for in antenna. the only reason i picked a flat is its easy to hide

    The main issue I see is that your local stations are all over the map as far as location. 140 degrees magnetic (ABC, NBC, FOX,) 240 degrees magnetic (ABC, CBS, CW), 216 degrees (FOX), 330 degrees (PBS , ION), etc. That means that antenna placement is crucial. If I was putting up an outdoor antenna I'd be temped to point it toward Raleigh, NC since at least all the majors would be coming from the same direction.

    Which Tri-Quest antenna are you using. I know they have a flat panel antenna, and conventional rabbitear/loop antennas. Like I say above your main problem is the fact that the major networks are coming from multiple directions so an antenna that is as "omni" directional as possible is a must for indoor reception.

    Of course you did have DirecTV so you may want to consider mounting one of these (Winegard MS 1000 Metrostar Omnidirectional Non-Amplified TV Antenna) on the DirecTV mount. It will work best if it is mounted above roofline. Just make sure to remove any "switches" from the cable so it has a straight run of cable from the antenna to the TV. The DirecTV mount should in theory already be properly grounded.

    DO NOT install antennas anywhere where they could fall into overhead power lines!!! An antenna falling into power lines may result in electrical shock or death. All outdoor antennas must be grounded in accordance with the National Electrical Code (NEC). Be careful while working on roofs or towers. Always use appropriate safety precautions!!!

    the tri quest is the flat panel which i assume is "omni directional" but i have to double check the model number. it does claim to get uhf and vhf channels. i put the antenna as high as humanly possible in the house today. about 16 inches from the ceiling and have the available channels coming in pretty darn good, considering its raining and overcast. i still cant figure out why the CBS and NBC channels are elusive considering the relative distance away. the auto program feature on my tv doesnt even register them.

    i did try the outdoor but dont have a mast on the roof since DTV installed one on the ground. even so the autoprogram only grabbed 2 channels when i put the antenna inside. i was thinking it would be stronger since it was an outdoor but i may have been mistaken on that one.....

    The second TVfool shows the NBC station to be considerably weaker than in the first TVfool. That explains why that may not be receivable on an indoor antenna, and CBS is VHF. The TriQuest will pull in VHF stations if the signals are strong enough, but it isn't big enough to do well on VHF, and those plastic covered mini panel amplified antennas like the RCA are a joke (definitely no good for VHF). You would be better off with a coat hanger (Folded Dipole Antenna : DIY TV Antennas ).

    a quick update....

    i performed an auto scan a few nights ago and picked up 23 channels. all of them werent strong enough to be watchable but i figured to go from 14 to 23 was a bit of a win. the weird thing is it pulled in CBS(channel 13) and it was watchable. i have done a few more scans since then with little to no improvement. why would it bring in CBS that one time and not anytime after? can i boost my cheapy antenna to duplicate those results?

    i'm also curious if my old direct tv dish can be converted to an out door antenna? maybe that would bring down more channels. it still has the "eye" that picked up signals for the dtv box.

    Unfortunately the "eye" for the DirecTV dish isn't designed to pick up OTA TV frequencies. DirecTV cables work great for OTA TV but the antennas only work for DirecTV frequencies. In an earlier post you said that the DirecTV dish was on the ground. That's a bummer since a roof mount would work well for mounting an over the air TV antenna. If you can find a way to mount an antenna above roofline that would be best. I'm guessing the Winegard Metrostar 1000 mentioned above would work in your situation.

    Pulling in channels 25+ miles away with an indoor antenna is very iffy, NBC at nearly 60 miles - never.

    Here's your main menu:
    ABC - RF 16 - 227deg. - 26 miles
    CBS - RF 13 - 227deg. - 26 miles
    CW - RF 21 - 227deg. - 26 miles
    FOX - RF 18 - 200deg. - 32 miles
    FOX - RF 30 - 126deg. - 57 miles
    NBC - RF 44 - 126deg. - 57 miles
    PBS - RF 31 - 345deg. - 13 miles

    All your signals are LOS (line of sight) at 25 ft AGL.

    Now, how to receive them...

    I think I would start off with an 8 bay "cat-whisker" antenna like the CM4228 and point it at 126 degrees.

    You might just get all of the stations off that one antenna.

    If that fails add a CM4221 pointing about 215 degrees to the CM4228 to get the southwest stations and combine them with a jointenna tuned to insert RF channel 44 into the line.

    The 4228 may be a bit of overkill, but at 57 miles why not be certain.

    Be careful, you might end up spending $150-200 on this setup, what's that 2, maybe 3 months cable bills.

    Yeah read elsewhere that if you're ditching DTV that you can remove just the dish itself, install the appropriate antennae on the mount and use the existing cables. I might be trying that out on our house here in a bit.

    That all depends on whether you have any switches between the dish and the receiver - if you do, they must be bypassed for OTA to work.
