In reply to MM3XGP:
I’ve made myself a little widget I find to be very effective - simply a piece of 100 x 38 timber about 100 long with a notch cut in one side and a taper planed onto the other - if I remember correctly the taper is about 1 in 7 for a standard trig. The corners on the side with the notch are cut at 45 degrees.
Place the widget against the trig point about 1m up, locate the pole in the notch with bottom resting on the ground, use a small-sized ratchet strap to clamp the pole to the trig point, position it just below the widget and it will hold the pole firmly in place. Set it up on the side oppsite the direction of the wind so the wind pressure tends to push the bottom of the pole inwards.
In very windy conditions a rucksack or stone (found locally - I don’t recommend carrying your own rock up the hill) ensures the bottom of the pole stays in place.
Works a treat, sets up in seconds. Anyone want to start manufacturing it commercially? I’m open to offers for the intellectual rights to the design!
If you’re confused by the description let me know your e-mail address and I’ll send you a sketch as an attachment
