once you've added postage plus import duty that may be added its harldy worth it with courtesy. For the sake of a five quid I would buy from the UK. You could see if ZMANALEX can get them or see if EH370 or Holdcroft would do any forum discount on the parts
I ran mine outside the house.
The only thing may be a problem is how do you control the Freeview box from upstairs. Not sure if you can get a equivalent sky eye for them. The RF feed out of the sky box is actually powered to enable the sky eye to work. So this would need to be checked.
for instance
we have sky down stairs. You can run a RF lead (standard TV coaxle cable) out the back of sky to your TV upstairs. Then you can watch any recordings or sky on ya TV upstairs. Also if you get a sky eye you can control the sky downstairs from upstairs. It connects to the RF feed in the bedroom. Probably the cheapest way of doing things. The RF feed will only be standard definition but if only on a small tv in the bedroom it will be fine.
got mine s2k stubby of fleabay. Easy enough and not seen any imitation ones just look at the photo of the item in the listing, you can see which are genuine as aftermarket items look different. The CR-V also uses the same aerial.
shouldnt come loose. Careful when re doing them back up. Think they need to be at a specific torque setting from what i remember so you dont overdo them
