Really good low VHF conditions this morning. KTVJ hit SNR 31 dB. KFTY better than I've been seeing it but still weaker than I think it should be by about 4-5 dB.

It's highly likely that your "Signal Strength" meter is actually a Signal Quality meter no matter the TV calls it. If the signals are already fairly strong, adding a preamp will not affect the signal...

You can't disconnect the power from the amp and expect to receive much of anything. It's still in the signal path and turns into an attenuator. You need a version of the antenna with no amp. As I...

You are probably overloading the preamp and/or TV. Under no circumstances should you be using an amplified antenna in Oakland. I'll wait to see your TV Fool report but I bet the NM column will show...

Pamajestic is right. You need an antenna with high VHF. The ANT751 might be enough for you if mounted outside. The Winegard HD7694P would be better. High VHF doesn't penetrate buildings very well so...

Those stations in green are very strong and if you can't receive them indoors then it's because of multipath issues. The only way to fix that is with an outdoor antenna.

None of the other stations...

The only thing that counts in reception is Signal-to-Noise Ratio (SNR). The highest SNR you can have is at the antenna terminals. Anything that occurs after that increases the noise and/or reduces...

The term "multi-directional" doesn't have any agreed upon definition for antennas so I have no idea what you mean. Wide beamwidth? If so, how wide? Totally different directions?

Looks like the...

Both TV Query and a CDBS search show the KOTR channel 11 permit as valid. KMUV HD is being carried as a sub channel on KION. I have no idea if KMUV digital 21 will ever come on the air.

K07ZK and KOTR are different stations, the former digital and the latter analog. It wouldn't surprise me if neither are on the air and neither about to come on the air.

If K07ZK-D is on the air, what programming are they transmitting?

You think that KOTR-LP (analog 2) will be back on the air? I'll keep an eye on RF 2.

I don't know what the actual length of the 7694P is. You should have no trouble receiving the stations on your list. They are all extremely strong signals. The only issue with the attic would be a...

I agree that the HD7694P outside is the way to go. The only qualifier I have with that is since you live right on the ocean the corrosion factor is high so in this case an attic antenna would mean...

You'd get more help if you start a new thread and follow the sticky above for antenna threads; your location in the title and TV Fool link in the text. Not much we can do for you right now.

Keith,

Have you checked the power output on KFTY recently? It is consistently weaker than it was a couple months ago. It was averaging 20dB SNR and now it's right around 16 dB most of the time. I...
