I definitely see issues - breakups and dropouts - on VHF during storms, and to a lesser extent on low UHF (RF channel 16). I think that's pretty widely acknowledged.


I don't experience any problems on RF channel 22 and above.

Impulse noise (of which lightning is a major producer) has always been a problem on VHF-low. It is even more problematic now that the VHF stations are transmitting at lower power since they have gone digital.

In my area, all the stations that will interrupt regular programming for severe weather information are all on the VHF high band. If there is a tornado forming nearby, I might miss the information during a dropout. Local radio won't tell me, because all radio programming these days is voice tracked and automated by a computer. The emergency alert system is only activated if a tornado is headed towards a metro population. DSL goes down during heavy thunderstorms, satellite TV cannot be relied upon either. NOAA weather alert radio is now the only option.

We have a thunder storm in progress at the moment. Our two VHF highband stations are an unwatchable, pixellated mess. It would be tolerable, except for the audio dropouts.



I admire your resolve to watch TV during lightning storm, I shutt off the tv

and only then stop trembling, alo

I should've said, thunderstorm in progress in an adjacent county. Lightning doesn't have to be close to ruin VHF reception.


If lightning's hitting around here, I unplug the TV and disconnect the coax.

You got that right! I live just outside the service contours of several hi-band VHF's. A thunderstorm anywhere near their towers (~60-75 miles away) will disrupt my signals. The other problem is co-channel interference.


I do realize, at my distance, I am lucky to be able to receive digital signals with any degree of reliability.

Both problems here, too. But we live inside the predicted coverage areas of the high VHFs, and are on a hilltop with LOS. VHF, at least at the power the stations have been allowed to use, just doesn't work well for fringe viewers. But UHF is excellent here.
