I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
One of the few remaining Chain Home Radar Masts at the old RAF Stenigot Radio Station. Nearly all of the RAF building have gone just leaving the Mast which is a Grade 2 Listed Structure. It's now used just for training people who climb/service antennas etc.
There are loads of farm tracks, entrances all around so plenty of take off spots and there isn't much else around to get in the way.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 16/07/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
