Hi
the mast can got to 20m, but i only extend to about 15m. this the head is level with the surrounding trees. it does move around in the wind, but with gust up to 565+ mph, it has stood this very well. there is an option for guy wires, but i have not gone for this. i got the mast from a company called 'total mast solutions' here in the uk.
the station is down at the moment, due to atechnical issue. i am having to return parts to rainwise, so hopefully be back in opperation soon.
