Certainly if you do not have a correctly working antenna - Yes , if maybe that the antenna is now faulty, certainly the terrestrial service is not know to have issues such as raid fade, if you are that way inclined you could check connection etc , but often the best place for analogue signals ie antenna height and location is no longer the best place for digital only reception  , failing that call a good antenna person - make sure he / she understands digital terrestrial reception

Once its fixed you won;t want to go back - because analogue SD just doesn't compare to Full HD

I've found out from Kordia that Haywards DTT is off air due to a power problem. Staff are on site now working on the problem, but apparently it's very windy up there.

If you're still using an old Sky UHF antenna then it's time you got a new one. You're probably getting water in the coax cable on wet days degrading the signal or the coax is no longer making connection with the aerial. Digital is not as forgiving as analogue when it comes to aerials. You need a good aerial and quality rg6 coax. The old Sky antenna is probably badly corroded with poor connections and leaky coax.

And there is a transmission problem at Haywards. It is off air at the moment.

He is saying he has lost it on several occasions , but obviously if the TX is down at presnt then he will have nothing at this time

Re Comments on old UHF Antennas . Checking with my meter the signal is often poor , lots of variation of MER and SIG level across the 3 Freeview Multiplex and Igloo .

I have found many of the old Balun boxes are water or corrosion filled , the connecting rivets to the driven element have corroded off and the old RG59 has filled with water . Also many of those old UHF antennas don't work well in the lower Ch30s group  .  Select a new one UHF Ch 25 to 50 region and put some new RG6 on!!

In some instances a new position on the building has been required for constant MER and Sig across the 4 transmitters !!

Thanks for all the comments.  The transmitter being down explains it - but it has happened before.  I may check the connections one day.
