So do i ignore the Grounding Screw as it is not needed and rely on the three pin plug to provide a route to ground?
Yes!

Just get a cradlepoint branch router and be done with it!
If you were to use a Teltonika RUTX11 (https://www.broadbandbuyer.com/prod...MI26fc0sGo7wIVVe7tCh1XEgtpEAQYBCABEgJTgPD_BwE) Mobile Router what antenna would you buy?
Indeed - which means that it (the PSU) does not require an earth (presumably because it is Class II).The power supply in the image cannot supply a safety Earth to the equipment as the Earth pin is plastic,
Again, indeed. The equipment itself is entirely ELV and does not require any 'safety earth'. Whether or not the equipment requires a 'functional earth' (for RF reasons) I couldn't tell you, but I very much doubt it (mobile phones work fine without an 'earth connection').The earth stud on the equipment may be a functional Earth for the radio equipment ( not a safety Earth ).
I don't disagree with that but, in a place where people often demand 'precise/accurate technical terminology' I thought it a bit odd that something with a markedly restricted (albeit vertical) beam angle should be called 'omnidirectional'.Co-linear antenna do have a narrow vertical beam angle but it is wide enough ( vertically ) to be suitable for most TX to RX paths in the UK ( mountains excluded ).
As I and at least one other have said, I see no reason why you need to use the groiunding screw - any more than you would need to find a way to 'ground' your mobile phone, even when it was plugged into a mains-powered charger.Accepting that i may or may not need to use this Grounding Screw in some way and i will have to get advice from the product manufacturer ....
I haven't got time to look at the moment, but don't the suppliers or manufacturers of it either sell, or at least recommend, a suitable antenna?to be certain i'd like to move forward and hope that someone could perhaps guide me in a way that i can purchase the best possible antenna for the Teltonika RUX11 mobile router.
Indeed, but I was thinking about directionality in the horizontal plane rather than isotropically.That is still making them more 'directional', by reducing the vertical beam width.
Kind Regards, John
Fair enough.The convention in the RF world seems to be that "isotropic" is used to reffer to an antenna that radiates equally in all directions, while the term "omnidirectional" is used for antennas that radiate equally in all horizontal directions but is non-uniform with different vertical angles.
True, and I would think that there would only very rarely be a need to cover appreciably more than 'half the sphere', since one would normally have no interest in 'downwards' (unless, I suppose, one was in a flying aircraft or high up a tall mounting!)Note that a truely isotropic antenna can't physically exist.
