we've moved from a persimmon town house to a lovely bungalow in a truly idyllic little norfolk village. instead of hearing cars and people's shit music playing on a saturday morning, i now hear lovely little singing birds - living in a town development has it's advantages (like close access to takeaways, could walk home from the pub on a night out with my buddies), sadly in those persimmon developments you tend to get quite a lot of arseholes, like our old neighbour who used to drive around in untaxed (and i assume uninsured) cars constantly.
anyway, the guy who used to live here (he sadly died about a year ago) was a bit of an inventor - there is some pretty clever wiring in the house that i'm slowly trying to understand, but what really confuddled me is this:

i found this in the loft, it was powered by a mains adapter - i'm just wondering - do any of you clever people know what it is? it looks like some sort of aerial, but as you can see it's fixed to a wall in the loft, it seems a bit of a strange place to have it. although it's missing out of the picture, the top of the pole just has a white plastic cap on it.
any ideas?
