what is the difference between a digital ready aerial and a hd compatible aerial?
Both are (arguably) ficticious terms/claims. A UHF TV broadcast is "the same" regardless of what they convey - digital, analogue, whatever. The only thing a "digital aerial" needs to do specially, is be optimised for the frequency range used at your transmitter - and these may differ from the range used for analogue, depending on the transmitter.
All radio signals are analogue; even if they are carrying a digital signal. The only time a different aerial is needed is if different ranges of transmission frequencies are needed.
As above and there aren't even any HD terrestrial transmissions yet
Thanks, but I already understood the frequency issue regarding different transmitters.
It is the fact that I have looked at various Digital aerials and in particular the Triax 343 is advertised as being HD Compatible. I wasn't sure if this particular aerial did something other Digital aerials do not.
Apart from including a bit of Marketing BS on the box, it's the same as any other aerial.
The pedants here would insist that you have looked at various aerials, not various DIGITAL aerials, because (all together now) "There's no such thing as a digital aerial"
It would be interesting to ask Triad to describe the special digital design features.
It is, of course, "HD Compatible". But so is any 20 year od UHF Aerial.
It is, of course, "HD Compatible". But so is any 20 year old UHF Aerial.
Or, indeed, so is a length of wet string if you live next door to the transmitter.
Don't forget that for HD digital television you must use HD compatible coaxial cable for your aerial downleads too; otherwise you'll negate the efficacious effect of your use of that special antenna in the first place

For some reason the Tiriax link isn't 'live' so try this
Triax - United Kingdom
Their explanation should be interesting
I don't need a HD aerial as iv'e not got a HD telly yet.
I think you chaps have summed things up nicely the only thing iv'e got to say i own a triax aerial i wonder if that will be good for HD.
Naughty Andy. Some may not see your tongue there in your cheek.
I phoned Triax technical dept. and asked in what way their "Digi 343" was "Specially designed for digital reception". Didn't get a very coherent answer! But they did mention that it had a balun on the dipole.

I think you can get some ointment for that !
Nice one about the balun.HA HA
I wonder if they know that baluns have been used since the year dot.
They knew that - but apparently their cheap "Contract" aerials are unbalunced.
I saw One for All brand amplified set-top aerials in Maplins that have marked on the box that they pick up HD TV. How confusing is that?
Thankfully not confusing for us on here or anyone you has read this thread,It's the non technical people you are going to get conned!
Yesterday i was asked this very question by a neighbour so i set them straight and also i told them to pass the info to other people they know.
