This is the property of the "Hound of Hounslow" (google it or see BBC) after searching his name on companies house website....was curious to see. The guy was alleged to have caused a flash crash on the US stock market where they said a trillion was wiped off. He would have been high frequency trading of stocks and maybe FX but cant think why he'd have an aerial like this. Certainly not for real time data as he'd use the internet for that.
He was thought to have made $70m over years, all confiscated. Doubt he would have been a taxi driver on the side!

That looks a bit like the old 405-line Band One VHF aerial to me, with a version of the 625-line Band Four or Five aerial part-way up the mast.
No old black and white two channel TV.
Sorry, should have given more information. (Not everyone is as old as me!) 405-lines was the "old" television standard which used VHF Channel 1-5 for Band one and 7-13 for Band three. It was superceded during the 1970s by the 625 line sets which received on UHF bands four and five, and this standard is still used today. IIRC the 405-line VHF signal was switched off in the 1990s, but, of course, FM radio still uses part of the VHF band, which is, or used to be known as Band Two. HTH
Have a quick squint at this. It covers the giant X, and giant H (other letters of the alphabet are also available 
)

Yes, I remember as a child in the 1950s and 1960s, everyone had an 'X' or 'H' aerial. But then, everyone had VHF tellies until the late 1960s.
What I'm not sure of is the difference in application of 'X' and 'H' aerials. Different polarisation?

The X aerial was a dipole and director (no reflector). Apart from being cheaper to make than an H, I seem to recall it had good nulls to the sides. The smaller aerial below is a wideband UHF aerial supplied by the rental chain DER. This installation has no band 3 aerial. Perhaps they didn't like ITV!

Not CB it is Ham, well is now, the old VHF TV frequency was given to hams. Although I would not expect a Ham to actually use the old TV aerial even if it is the correct frequency. Seem to remember it is the 4 meter band the old TV shown here was the old 405 lines.
