I have been using my Humax freesat PVR connected to a single lnb. Was talking to my neighbour today. He has n unused connection on his Sky quad. Our dishes are three feet apart. Could I run a cable from his dish to my box?
Humax 2nd lnb.

Yes and no. You would need to make sure the dish is earth bonded by a competent electrician. If as is highly likely (and usual) your mains power supply is on a different mains power phase to your neighbour. Any serious electrical faults on electrical equipment connected to the satellite receivers (TVs, amplifiers or anything with a common signal earth that is not actually connected to earth) could cause a hazardous and potentially lethal 400 plus volt on equipment at the other house. Correctly earth bonded then no problem.

Dual LMB's can be found quite cheaply < £10.00. Replacing a single for a dual is easy. I would spash out on a good quad.

So how does that work Dave, I have yet to see a Sky installation with earth bonding on a dish.

You only have to earth bond the screens when a single dish feeds more than 1 property. As Dave says your neigbours will have a feed from a different phase to yourself. Your supply is 240V phase to neutral, so is your neighbours, IF you were to connect a voltmeter from your live feed to the neigbours you would get a reading of 415V. Under some circumstances it's possible to transfer this voltage across the common screen connection earth bonding this prevents this happening

No, it's because they don't do the job properly. Dishes should be earthed for lightning protection.
I know of one case where a Sky contractor fed 3 houses off one dish with no earth bonding. He was touting around for a fourth which is how I found out about it.
Thanks for the information guys.
Presumably then this is also required for installations on multi occupancy buildings where each unit (flat) has its own metered supply.

Strictly speaking yes but a lot of houses converted to multi-occupation only have the original single phase power supply entering the building and would not be absolutely necessary in those cases. Larger blocks of flats have multi phase mains power entering the building.
