    Antenna help - Parker, CO

    I live in a suburb about 20 miles southeast of Denver, and I've had a really hard time getting OTA signals to come through consistently. I'm through constantly adjusting the antenna just to watch TV, and looking for a permanent solution that will yield consistent channel viewing. I'm currently using an Antennas Direct CSM1 w/ amp mounted in the garage (which is on the other side of the house from my TV), connected to my TV through coaxial. Here's my TV Fool report:

    TV Fool

    Currently, I can receive Fox (ch. 32) and CBS (ch. 35) without any issues. ABC (ch. 7) and NBC (ch. 9) are the real tricky ones. ABC comes in at about half signal strength, with occasional cutouts. NBC I can't get at all.

    I'm considering switching to an outdoor mounted antenna, and was wondering what would be the best for what I'm trying to get.



    Thanks in advance for your suggestions!

    Would you mind rerunning your TVfool report for a rooftop antenna height? Say 20 feet. The micron antennas aren't designed for VHF-high (7,9 and 13), so you really should consider a dual band antenna or two antennas. One of the big issues with TV reception in the Denver market is the fact that, due to enviromentalist meddling, the broadcast towers are spred up and down the front range from Squaw Mountain in the South to Fort Lupton in the North. Even so, with the right roof top antenna set up you should get 30+ channels. Based on the TVfool you're showing right now, I'd go with a VHF high antenna like a Antennacraft Y5713 or Antennas Direct C5 comboed with a 4 bay bow tie antenna like an Antennas Direct DB4e or a Channel Master CM4221. You would connect the two using a UVSJ. The C5 comes with a UVSJ.

    Snappy Dan Reminds You:

    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!!!

    I also recommend checking out the antenna system I use here in Monument.

    Here's the TV Fool report rerun with a rooftop height:

    And if you don't mind, how much did your current antenna set-up cost? (ballpark)

    Second, how difficult is it to set-up?

    Thanks for your help—it's really appreciated!

    As I suspected, raising the height improved your TVfool report greatly.

    There is less than $20 of materials in each antenna. Of course I got my baluns at OEM Parts in Colorado Springs for $2 a piece. You can get all the parts at Lowes or Home Depot. In Parker you may not need an amp.

    I do have two of the loop/dipole antennas that I've been selling to people for $20 a piece. My cost, not counting labor, is like $10-12 when I buy materials in bulk. We don't live that far apart. About 30 miles based on our TVfool reports.

    Most of the bends on the Gray Hoverman are 90 degrees. I built mine in about an hour.





    The insulators are 1/2 PVC pipe "T's" that are $0.25 at Home Depot.

    The main cost becomes the UVSJ which is $6.74 with shipping and handling.

    Peter, I am in Parker also ... I purchased a CS5 but have not permenantly installed it (attic or roof).
    Inside the home, I am getting approx 30 channels with the CS5, but looks like I have the same initial results as you ... the major networks that come in are PBS and CBS. ABC and NBC are the difficult ones, and I haven't had a lot on NBC yet.

    Were you able to acquire NBC? If so, what antenna did you end up going with?

    You either need an antenna with VHF performance, or a really good spot for your UHF antenna (to make up for the fact its VHF gain may be low or even negative).
    nbound-au is a qualified Antenna, Satellite, and MATV installer.

    I live in DVB-T land.

    So I bought an Antennas Direct C2-V-CJM ClearStream 2-V.

    Now I get the ABC affiliate 7.1 with full bars, but the NBC affiliate 9.1 is completely dark. (And all the channels are coming just fine as well)

    Any ideas?

    Several things:

    Try an FM filter at the output of the antenna. While your location is terrain obstructed back to Lookout Mountain, there are several FM stations that transmit from Mt Morrison (near Red Rocks) that are not obstructed and their power will be much stronger than the signals from channels 7 & 9. Radio Shack sells an FM filter for about $5. Item # is 15-0024.

    Are you still using the amp (which one?) mentioned in post 1? If so, remove it (or use the FM filter in front of it).

    Have you tried multiple mounting locations? You're behind a a hill and signals bending over hills are usually non-uniform in their peaks and valleys.

    Most of all, are you still mounted inside the garage?? If so, it's miraculous you get any of those 2 edge stations! LOS (Line Of Sight) is infinitely preferable. According to the TVFRs, and just common sense, installing on the roof is the way to go.

    Channel 7 (KMGH) has two transmitters. One is VHF (channel 7) and one is UHF (channel 17, KZCO). VHF signals have more issues going through walls. If your antenna is still indoors, outdoors may be the solution. Personally, my VHF antenna is outdoors because that's where it needs to be to get good signals, and my UHF antenna is indoors. I'm picking up the Denver stations here in Monument (48 miles and second edge). All the Mount Morrison and Lookout Mountain full power stations and KZCO off Lookout Mountain come in.

    Thank you ProjectSHO89, I'll try the FM filter you suggested. I'm still confused as to why I would get a crystal-clear signal for channel 7, but not channel 9. (Admittedly, I don't understand much of the theory behind signal transmissions, but it would seem to me that if FM signals are blocking 9, then they would also be blocking 7).

    The amp I'm using is the amp that came with my original Antennas Direct CSM1.

    Rickideemus, no I'm no longer inside the garage. I've mounted the Clearstream 2-V externally, in the NW corner of the house, at a height of about 15 feet.

    Unless you're actually getting KZCO on real channel 17. The broadcast signals are identical except for the channel they are broadcast on. Both map as 7-1,7-2,7-4. Unless you have a television or tuner that shows the actual broadcast channel, you will not know the difference.

    Ah...that explains it. After running the auto program on my TV, I ended up with two sets of 7-1, 7-2, and 7-4. One set has full bars, the other barely two. My antenna must be picking up the KZCO broadcast, as you said.

    Haven't been able to pick up the FM filter yet, but I'll report back once I do!
