Yes, because certain analogue TV station uses >700MHz range, so the LTE/5G services can't be used in 700MHz band.
But to think again, even if it shuts off now, the 700MHz spectrum will be vacant for quite some time (except some digital TV transmitters that uses 722MHz frequency)

So in other words, rush so fast to shut it off also, still have to wait at least Q3 2020 to be able to start enjoying 4G/5G services on 700MHz.

But despite this, I wish to see analogue TV to switch it off as soon as possible.

If I would guess, what would be the main advantage for RTM and Media Prima if they switch off analogue sooner?
Well, they can start enjoy savings for no longer need to pay electricity bills for operating the analogue transmitters.
Disadvantage? They'll lose the remaining viewership from analogue viewers who haven't switch to digital.

Very good. That's more like it. 
They should have demonstrate this comparison many years back, not days or a month before ASO.

Shifted to 10pm, as per demands.

Astro already show in HD ke for TV1, TV2, TV3 and others free to air channel?

I just realised today that it appears that in Klang Valley, all analogue stations from Bkt Sungai Besi and KL tower has gone completely off air, No Signal at all, no more showing ASO message.

just received this SMS despite never use any of the service nor register interest with myFreeview before, is it send out to everyone or only interested users?
