Thanks Lucid, I kinda thought that would be the case, is the one in the link of decent quality or are they all much the same?.
Thanks.

Below 145.000, with exception of RAYNET what little survives, it is digital, be it Morse, SCTV, or AMTOR, they are digital modes, so an aerial designed for 144 to 145 is in real terms digital, above 145 to 146 it is analogue. Most of the band plan is split into digital and analogue in some way, be it 20 meters or 2 meters does not really matter. Maybe not HD but there is HF. As far as TV goes, digital means wide band, and today there is very few places where a wide band aerial is still required. There is no longer any analogue TV, and the band plan is very much reduced from the old analogue days, so any aerial advertised as digital I would steer clear of, as likely designed for the old band plan, so will have far larger wind resistance and weight to today's aerials. Aerials have colour codes which match the aerial to the area. Buying an aerial local one will expect the correct band, but using distance buying you need to stipulate the band required.Thanks Lucid, I kinda thought that would be the case, is the one in the link of decent quality or are they all much the same?.

It's misdescribed. These is no such thing as a digital aerial. There is no such thing as an HD aerial either.
As far as TV goes, digital means wide band
It states Forward gain is 11.3 dBd. That's not what I'd call "high gain". In fact it only just exceeds that of a V10-36L and, bearing in mind that 11.3 is the peak gain, its overall gain will actually be lower than that of the V10-36L, whose gain spread is almost linear across the band. Here's a comparison graph with relatively high-gain Yagis at 13.5 dBd and moderately low-gain logPs.At last I got an advert that gave details It gives weight, db gain, beam width, and channels covered at last an add with details. However for me I don't need 16 db gain.
I've no problem at all with the idea of choosing exactly the right aerial for the job. If all the frequencies to be received are bunched in a tight little knot, and you know for absolutely certain that there no chance of that frequency distribution changing any time in the foreseeable future (let's say 10-15 years) then definitely go for a grouped aerial because it will give more gain and a greater signal to noise ratio. The problem is though that the goal posts keep shifting.Sam is correct, the aerial needs to fit the job it is doing, having too much metal hanging off your roof is just asking for further problems.
If you're a masochist, maybe. The rest of us live in the real world where we just want a good solution with the minimum amount of hassle.There is no reason why you should not make your own aerial.
