I am sorry to learn that you are having trouble receiving the KVIE signal all the time. We are broadcasting at full FCC allowed power on VHF 9. The broadcast signal is not raised or lowered. It is the same 24 7. We are using the same tower as Channel 40 in Walnut Grove.
Our engineers recommend a regular UHF/VHF outside antenna. Are you having trouble with KXTV 10? Both KXTV and KVIE are now VHF TV stations while 3, 13 and 40 are UHF. Your antenna needs to be both UHF and VHF ready to receive all of the Sacramento based TV stations.
Are you running more than one TV set off your antenna? Using a splitter will drain away signal strenth even if the second set is not on.
We recommend one solid coaxial cable. Not cuts or repairs in that line.
If you antenna or cable are more that 20 years old it is time to replace them.
Viewers in out laying areas are finding that adding a pre amp to the antenna will help.
Hope this helps
If anyone can shed some light on this I would really appreciate it.
Thank you for taking the time to help.
Trying to reliably receive VHF signals with a UHF antenna will often cause grief such as yours. It will work well enough when conditions are good enough, but will fail as soon as the atmospheric conditions change slightly. Daily variations in atmospheric signal propagation are common.
Install the correct antenna to fix the problem.
In addition to the wrong antenna you could have FM stations that interfere with VHF. Try using an HLSJ as an FM trap. (Leave the L port blank, use a 75 ohm terminator, or connect it to your FM receiver.)
Thank you both for your input.
Since you report that you are repeatedly losing and regaining these two signals at 6pm and 6am respectively, perhaps there is some kind of electrical event in your vicinity (perhaps on a timer of some kind) that is becoming active at 6pm and knocking out your signal until 6am, when that event stops. One possibility could be nearby outside light timers (either yours or a neighbor's).
In any event, adding a dedicated VHF-high antenna to your 4221, and joined with a UVSJ, should increase your signal strength on those two VHF stations so that they overcome whatever local interference you might have.
Thank you again everyone for all your help.
Perhaps, not only will they/he/she be receptive, but also compensation will could be rewarding.
I'm thinking the best and easiest solution will be to move the antenna tho. My neighbors and I don't really talk too much, and I think if I try and bring up the fact there pot farm is interrupting my Charlie Rose, and Frontline, well it would be awkward at the least. I only know about the pot, because I get strong wiffs of it on occasion.

DTV Reception 24 7
by Charles W. Rhodes, 04.05.2011
The first time I received an e-mail about DTV reception only during daylight hours, I was dubious. More recently, a reader in Humboldt County, Calif. wrote that reception in his town folds at sundown. He wrote that "grow lamps" are automatically switched on in many homes then. Those fluorescent lamp fixtures have solid-state ballasts that generate and radiate a lot of noise that falls within the low-band VHF channels. There's a local station on Channel 3 there. He also explained that there's a thriving agricultural industry in growing marijuana plants for fun and profit in the county. This man-made noise problem is fairly minor today, as there are only 38 low-band VHF band full power stations still in operation.
Other reports have trickled in so I've given some attention to other possibilities.

I showed this thread to the boss. You'll likely see some mention of it (or the subject, at least) in a future blog post of his.
Korn858, I realize you haven't posted on this in 2 1/2 years but hoping you will still get this..... I recently moved to pleasant hill and I am trying to set up my antenna. Its a CV2. I haven't been able to get more than 10 channels and have moved it all over my roof. Any advice you can give me!?!?!?
Thanks for your time
You are most likely to find the help you need if you post in the San Francisco or Sacramento threads of the forum above this one depending on which stations you are trying to receive.
FWIW the CV2 is a UHF antenna, so write off the VHF stations. The range isn't all that great either. You may need more antenna, and a rotor, or even multiple antennas to get what you want. And it is still going to be iffy with all the hills around.
You are confusing the C2V with it's predecessor model C2. The C2V has been around for about two years.
The C2V has a VHF dipole strapped on the back which is likely to be effective out to a max of 25-35 miles on VHF, depending mostly on the local VHF station's power level and the individual signal path. Personally, I've used it out to about 55 miles, but I cheat with my Sencore handheld spectrum analyzer.
