Cable hazard at Odiham is marked on 1/2 and 1/4 mil CAA charts; if you use someone elses publication (which won't necessarily be checked for accuracy as rigorously as the CAA one) it might not be; Jeppessen policy for instance is NOT to show cable hazards on their VFR/GPS charts. There's a similar hazard at Lasham too, this time 3700ft amsl!!
