I'm receiving Freeview from the Oxford transmitter using the right sort of rooftop antenna. Most of the time it is perfect, with the Humax PVR reporting at least 95% signal and solid 100% quality, but on some days there are occasional brief (fraction of a second) interruptions where the signal goes to zero. Is it conceivable this could be weather, or is it more likely flaky wiring?

P Wallace:

These sorts of intermittent type problem are often the most difficult to resolve.

Whilst I was going to say that it's unlikely to be weather related because of the way you've described your issue, it's possible that things like "Tropospheric Ducting" might be a (the) cause (there have been periods of this in recent times), but you should notice other factors if this was likely. See How does good weather affect my television? | Help receiving TV and radio for a rather simplistic and crude explanation.

Basically it results in interference from more distant transmitters in the UK or Europe. This is usually quite frequency dependent - in other words not all multiplexes may be affected, it could be just one. The effect may only last briefly, but because it's interference to the wanted signal, you should also see changes to the signal quality - again it could be brief. More typically the quality will drop (as may the strength but not always) until the set cannot decode the wanted signal. This can last for seconds, minutes or even hours depending on the precise weather conditions.

If the issue is affecting all multiplexes, the problem could obviously be an intermittent connection (flaky wiring!) there would usually be something to disturb a connection eg. equipment vibration (maybe due to usage - button pushing etc.) or more often disturbance to the aerial connection or downlead usually wind blowing either about, maybe a bird landing on the aerial, and so on.
The best way to eliminate this as a potential cause is to check every coax plug connection especially for corrosion, any ready made flyleads which can develop intermittent faults at the back of the plug etc.), check the downlead is secure and not flapping in any wind, check the aerial connection if you can access it.

Your issue does sound more like electrical interference from a "switching" spike. Does it occur at (exactly) the same time of day - could be something switching on a time-clock, could be things like boilers coming on or going off, fridge or freezer thermostats going faulty, particular lights being switched on/off, ...and so on.
It's a tiresome task of checking around to see if any such events happen at the instant you have the signal drop. The worst is it may not be on your premises, it could be a near neighbour, or even something commercial nearby where perhaps more "heavy" equipment switching is involved. These latter things are less likely but nevertheless possible, try and eliminate anything on your premises before worrying about external sources.

HTH. Post back with any further info that maybe helpful or queries if you need more help.
