Hello John
Many of us do well with poles of just 4m, 5m or 6m in length, 10m is too long and too heavy for me these days and unecessary. As a user of 4 band HF link dipoles used as an inverted vee, having a 5m pole means I can reach the links for 20/30/40/60m from ground level. It also means if you buy a “travel pole” which packs to 57cm it fits inside your rucksack and is out of sight of people you may meet on the trail, so no questions are asked.
Trouble is the shop I use is out of stock at present:
https://lifebreeze.co.uk/collections/travel-telescopic-poles but you might find them somewhere else if you are interested in going down the travel pole route…
Good luck with SOTA!
