Who told you that? It's not true.

Five broadcasts on MUX A, along with QVC and most (all?) of the topup tv
channels like UK Gold. If you get MUX A, you get Five, it's that simple.

Caradon Hill broadcasts on the following channels

UHF 21 Mux B (BBC4, Parliament, interactive video feeds and more)
UHF 22 BBC1
UHF 24 Mux C (Sky News, E4+1, and more)
UHF 25 ITV
UHF 27 Mux D (The Hits, TMF, ITV Play, many radio stations)
UHF 28 BBC2
UHF 31 Mux 2 (ITV 1/2/3/4, C4, More 4, E4 and more)
UHF 32 C4
UHF 34 Mux 1 (BBC 1, 2, 3, CBBC, News24 and more)

UHF 48 Mux A (C5, Topup TV, QVC)

To get all the channels, you'll need an aerial that covers UHF 21
through 48. (Note that Mux 1 is 5kW, Mux 2 and A-D are 4kW). Your
current aeriel was probably in "A" group, which gives high gain for UHF
21 through 37, but nothing for anything past that. 

A "W" antenna will give near-uniform gain on all channels, however that
gain will be lower on channels 21-37 than your current "A" one. A "K"
antenna would probably also work for now, covering channels 21 to 48
inclusive.

As only Mux A is out of band for the area, and as the only channel of
interest is Five, most people will assume they don't get it as they
don't get 5 on analog (Five does braodcast from Plymouth at very low 
power on UHF 30, well outside the standard ananlog transmissions from 
UHF54-64)

With a wideband aeriel you should get MUX A (if you get the other muxes
too)
