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.
