they're radio antennae, probably UHF on one side, FM or another channel on the other (so says my brother, who knows a bit about theese contraptions). will find out more when dad comes off shift, he'll be able to tell me for sure.
right, dad's on the lookout for a schematic, be able to tell you soon. definitely not an FM antennae though, he was able to tell me that much.
he's going to ask the lads at work tomorrow :P
he's more of a nimrod expert, but he knows who to ask to get the answer you need :)
