[QUOTE="smoggy07, post: 871178, member: 298987"] If it looks like a TV antenna then it will be a Yagi for point to point comms as mentioned above Was that location used by the railways in the past as they use (or used to use as it is being phased out in favour of mobile phone tech called GSM-R) band3 VHF comms and also UHF for "Cab Secure" radio and you'd often see Yagi antenna dotted along the trackside to provide coverage (you'd also find one at either end of tunnels pointing into the tunnel to provide cover inside the tunnel) They point them at each other along the length of the tracks so the drivers can raise the signal men or anyone else they might need and can look similar to the attached pic [ATTACH]61418[/ATTACH] Next time you are there follow the line of sight and see if you can work out the intended recipient or get a rough idea of where it is pointing, it could be aimed at a hill top repeater site [/QUOTE]
