I just have to recommend Mark from Hi Tec Antennas.
Great bloke,knows what he is doing and OK and safe to have in the house.
He installs/ fixes antennas,does cabling for TV/Hi Fi or even sets up that mass of wires wanting to be a TV/DVD/Hi Fi system.
He has done loads of works for us,friends and forum members.
Very reasonably priced - too cheap I say!
Based in the south.
His number is 0412255833
