I presume the yellow/green wire is your connection to an external earth rod. If so, and you have a PME domestic supply (very many in the UK do) but no heavy-duty (10mm2 minimum) connection from your earth rod to the consumer unit earth, then this is contrary to the electrical regs and could cause a fire in the event of a neutral break along the supply line. Not only is this bad, it could be ruinous, because the breach of regs may well mean your property insurance would be invalidated. This is a common and serious error and one that even the RSGB have made in print.
I totally agree, our supply is TN-CS to the house and this is a potential problem (no pun intended). There are workarounds where you can legally use a different scheme for an isolated room but with some stipulations. Unfortunately much of the advice on the internet is from the USA where physics works the same but wiring regulations are different. I suspect that many UK installations are wrong, and I must confess to not being above criticism...
ERICO Copper Grounding Bars provide proper bonding; essential to create an equipotential plane between service grounds and shack equipment. This equipotential plane provides a near-zero voltage differential and serves to protect people and equipment during transient and electrical-fault events. These ERICO grounding bars have a series of 0.281 in. diameter holes that accommodate mounting many items, including Alpha Delta, PolyPhaser, and other surge-protection devices. They include stand-off mounts that deliver extreme isolation from the mounting surface. When used in tandem with ERICO ground rods and ERICO CADWELD ONE SHOT Wire to Ground Rod Clamps, there is no better grounding system available… period! These ground bars have a 1-1/16 in. standoff of their stainless mounting brackets plus a 1-1/2 in. insulator. This places the inside of the ground bar more than 2-1/2 inches from the mounting surface. There's plenty of room to work after mounting the bar. These bars may be mounted horizontally or vertically and the mounting holes in the copper bar are 8-7/8 in. on center. These grounding bars provide a convenient, reliable grounding location. Their quarter-inch thick solid-copper bar represents the ultimate in ground connections. ERICO grounding bars include insulators, stainless steel brackets, stainless steel mounting bolts, and are UL Listed. For premier grounding at your station, rely on ERICO Copper Grounding Bars from DX Engineering.

Gotta love these videos...no fancy schnazzle just a normal operator's shack shown how people want to see it 👍👍
very nice

Where did you get that buzz bar John will get one when I change coax for this M&P extraflex bury 10 stuff great video 73 DZH

Interesting and informative thanks mate.
Glad you enjoyed it
Plenty of ground loops, good if you want to cause interference..
Where did you get the braided earth strap I could do with some of that cheers great video thanks for posting
DX engineering john
@@hamradiostationg0dtx583 Thank you. Great setup you have cheers
Where did you get the copper braid from need some for my mobile antenna on my car? Thanks DE 2E1FUE
you can get them off eBay but I got mine off d X engineering hope this helps 73
@hamradiostationg0dtx583 Thank you for the information. I will try to get the 28mm one about 1m for the car. Thanks again, De 2E1FUE.
great video again john
Thanks for watching
Just a heads up...This seriously needs to be bonded back to the consumer unit if you're on a PME system...
Thanks for info

@@hamradiostation_M0UGE THANKS WILL HAVE A LOOK
Hi this is M1DAT Rob, was wandering were you got your braid and ring connector and how much. Look forward to hearing from you, many thanks.
dx engineering i can not remeber the cost
I don't bother with grounding. My world hasnt ended.
OH good from HL5 call 73!!
Thanks 73
Looks a bit overkill. How effective is rf grounding when your shack is on the first floor?
No rf in the shack happy days 73
If you would use a balanced dipole antenna, you wouldn't need all those ridiculous magnets and straps!
it's for noise coming from the neighbours not rf its for qrm on the coax.
LOL! @@hamradiostationg0dtx583
