Spiderpole 12m made by Spiderbeam is very useful for portable ham radio activities. To do the job it must be properly anchored. This pole may be anchored at the bottom (at about height of the first element) which allows it to withstand wind speed of abut 80 km/h, and at 7 meters high using guying lines (as recommended by manufacturer) which allows surviving windows of 120 km/h.
Anchoring at the bottom seems not suitable for portable, as it requires either to have already set strong short pole (fence or something) to attach pole, or dig one into the ground. Using guying lines seems more suitable for various situations.
