9 (KUSA) in Fort Collins
http://www.tvfool.com/?option=com_wr...e1c6648ad46141
I'm having a difficult time with channel 9 (KUSA). I have one of these mounted on the roof. Sometimes I can't get channel 9 at all, sometimes it works flawlessly, sometimes it's watchable but the picture and audio breaks up occasionally, sometimes it comes in but is unwatchable due to breakup. Any ideas? |

The tvfool report is not showing any antenna height above ground. Do Not Delete the tvfool report that is not showing any antenna height above ground. Please make and post a tvfool report that has 25 feet antenna height above ground. 25 feet antenna height above ground is a reference antenna height that provides a good evaluation of what is receivable. |

Thanks for the reply. I think you're right about the amplifier in the Lava antenna. I have to turn the amplifier all the way down for best performance, but even then, reception is as described above.
Why is this only affecting channel 9? According to the map, the stations I want to receive are all the same distance and direction. Why do the rest come in perfectly? Also, what antenna would you recommend? I prefer something compact if possible. |

The Lava antenna would not be on my list of antennas to consider, due to build quality, poor durability, grossly exaggerated performance claims and price.
If you want to receive the Denver stations I'd suggest you use an antenna or combination of antennas with both UHF and High-VHF capability. If I was in the same situation, I'd start with an Antennas Direct DB8E and an Antennacraft Y10713. The DB8E allows you to aim the two panels independently, so I'd try aiming one panel south and the other west. I'd point the Y10713 south, at the KUSA transmitter. I'd use an RCA TVPRAMP1R preamp which has inputs for both antennas... Though I would perform this test before spending any money on the preamp. Don't use a preamp if you don't need it. If the unamplified antennas are able to deliver enough signal on their own, simply use an Antennas Direct UHF/VHF signal combiner instead of the preamp. |

The Lava antennas are pure and absolute junk. Cheap plastic. Cheap Soft aluminum. Cheap metal that corrodes fast. Cheap little electric motor and gears that turns antenna. A Cheap amplifier that overloads easy. -------------- The Number 1 situation/problem with reception along the front range is Multi-Path Tv signals bouncing off the hills and mountains , trees and tree leaves. For reception at your location install antenna that is directional to a greater degree in the forward direction so as to reduce the reception of Multi-Path. Above the Peak of the Roof install a , http://www.antennacraft.net. HBU44 antenna aimed at about 187 degree magnetic compass direction. Here is how to aim antennas , http://www.kyes.com/antenna/pointing/pointing.html. Use a Real and Actual magnetic compass to aim antenna , do not trust a cell phone , tablet and etc. compass. -------------- A antenna system amplifier will most likely not be required. For 1 Tv connected use No splitter. For 2 Tv's connected use a 2 way splitter. For 3 tv's connected use a 3 way splitter. --------------- Here are some above the roof antenna mounts. http://www.ronard.com/909911.html. Install the , ronard(911) , 5 foot tripod antenna mount. http://www.ronard.com/34424560.html. Install the , ronard(4560) , eave antenna mount. http://www.ronard.com/ychim.html. Measure around the chimney and install a , ronard(2212) , ronard(2218) , ronard(2224) . http://www.ronard.com. ---- Home Depot has , 10 foot 6 inch lengths of 1 and 3/8 inch diameter , TOP RAIL , chain link fence , PIPE , that makes good antenna mast pipe , the price is low at about 10 dollars. |
Thanks for the suggestions.
Those are HUGE antennas. Is that the only way to get channel 9? Why does 7 come in perfectly? Shouldn't I be having similar issues with channel 7? Is there something specific about channel 9? Also, is a preamp always needed for cable runs of 50 plus feet? Or is it more complicated than that? |

You can Test reception with a , www.channelmasterstore.com , CM4228HD antenna aimed at about 187 degree magnetic compass direction. Use a Real and Actual magnetic compass to aim antenna , do not trust a cell phone or tablet or etc. compass. Test reception With Out a antenna system amplifier. And Test reception With a , CM7778 preamplifier. For 1 Tv connected use No splitter. For 2 Tv's connected use a , Holland Electronics , HFS-2D 2 way splitter. For 3 Tv's connected use a , Holland Electronics , HFS-3D 3 way splitter. Buy the , HFS-2D and HFS-3D , splitters at , www.hollandelectronics.com , or , www.amazon.com |

If I went with a DB8E and a Y10713, would an attic install be okay?
|
Impossible to say since no one knows what the signal environment in your attic might be. All you can do is try it and see.

Attics Are Not a reception friendly environment and Never Will Be a reception friendly environment. The Only Way to discover if reliable reception will happen in the attic is to install the antennas in the attic and see what happens. |
Would the Antennacraft U8000 be a decent alternative to the DB8E at half the price?
|
The DB8E offers slightly better gain than the U8000. That by itself is not a dramatic difference. However, the DB8E has greater flexibility when aiming... The two sections can be aimed independently, which is a major plus in your specific application.

You guys have been a huge help so far, but I'm still having some major issues. I figured I would just add to this thread rather than start a new one.
I ordered a Y-10-7-13 and the RCA preamp. I hooked them up in an upstairs bedroom for a quick test. Channels 7 and 9 didn't even come in as good as the Lava piece of junk on my roof. I hooked up my old Clearstream 4 too. Nothing on UHF. I left to run a few errands and returned to find every channels' signal strength nearly at 100%. So, I drag everything up to the attic for test number two. Same as before my post-errands miracle - channels 7 and 9 are really weak and nothing on UHF. But fast forward a few hours - every channels' signal strength is nearly at 100%. After three or four days of near perfect viewing with the antennas in the attic, I'm back to the beginning - channels 7 and 9 are really weak and nothing on UHF. What could possibly be causing such wild fluctuations? Quick note: when I say channels 7 and 9 are weak, sometimes both channels are around 50%, sometimes channel 7 is at 0%, sometimes channel 9 is at 0%. I don't think I've had both channels at 0% yet. I have had both channels near 100% though. This is so frustrating! |
If your C4 has the older "black box with silver flat combiner bars", the circuit board may be cracked causing intermittent or no reception. Call customer service at 877-825-5572 for a free warranty replacement.
I see you're still putting your antennas in the attic then comparing their reception to the antenna up on the roof. The observation that the antenna on the roof is working far better than the much more capable antennas when stuffed into the attic should tell you what you need to do. |
