Argos are selling Philex Aerials (14 element,up to 10db gain) for £14, and (32 element, up to 12dB gain) for £24.
I live 22km from the Crystal Palace transmitter and i'm told from the Freeview Page i need a *AH* type aerial for this transmitter.
Are these aerials the AH type?
Is there likely much *real* difference between the effectiveness of these two aerials, or is the difference just marketing?
So a group A (which is correct for Crystal Palace) which is mounted horizontally.
No, anything sold nationally by like likes of B&Q, Argos etc is likely to be group "W" wideband, so it will work (but not optimally) everywhere rather than being transmitter specific.
presumably the ones on offer are these?
The thing is with all the retunes, TV has lost, and will continue to lose, the higher frequencies for mobile phones to use, to start with group A is the lowest group of frequencie anyway, so a band W is not ideal for you, you won't use any of the higher frequencies it receives, which include 4G phone signals that could interfere with the TV signals.
Every 3dB increase amounts to double the signal power received, so in this case about 60% increase.
You could look for "proper" group A manufactured by e.g. Blake, but Bill will be a long shortly to tell you you the world has fallen out of his bottom since everything can be received on a bent coat-hanger these days ...
In the late 1980s I sawa pile of "cleaners coat hangers" in the window of the Oxfam shop in Warwick. They were labelled "car radio aerials" and priced at 10p.
Yes, and no. If you are in a marginal reception area, or suffer from specific interference from another transmitter, then a better aerial may solve most of your problems.
I ran for the first few years of digital with a loft mounted yagi tuned to entirely the wrong band for digital!
It worked pretty well, but the log periodic I stuck in on the correct band post analogue switch-off was a lot better on one multiplex - the one furthest from the old analogue band.
At 22km assuming no hills between, almost any yagi or log periodic should work.
Hehe, as long as it's outside I can indeed receive the majority of the available Freeview channels on a bent coat-hanger :) At least on the dongle plugged into the laptop...
Now, if I could say the same for the local DAB stations... :)
Back on topic, ish, I noticed after the stormy weather a little while ago that my TV aerial is now upside down*. It's still pointing the same way and it works just as well so I've left it alone :)
*oldish 18 element Antiference, it's swung round on the "u-arm" and the cable entry and elements are now on the bottom rather than the top.
To cut to the chase, I suggest you avoid buying such horrible s**te. Get on the CPC website or ATV Aerials Sheffield and buy a log-periodic. It's that simple.

And cheaper.
Have you noticed how a lot of these DIY aerial fall apart quite quickly? It's remarkable really.

Our pigeons can destroy any aerial. The CPC log periodic lasted 4 months.

Cable ties - with pointed ends facing up keeps them away. I presume they have no effect on the signal.
Very unlikely - most stuff sold in general shops will be wideband (aka group W). Alas the performance of a group W aerial is poorest in group A.
