> Wonder why they not offer to use the fix rate envelope USPS supplies. USPS has several different forms of fix rate shipping. Elkraft, I'm told, is using that when they ship their radios.

Because the heavier-walled adhesive-lined tubing cannot be bent or coiled without some damage, and they supply it in 4-foot lengths. They ship it in a rigid cardboard tube.

BTW, I only use it on the backshells as strain relief and as a starter for wx sealing. Big fan of self-vulcanizing tape here for field joints. Adhesive shrink is fairly miserable to remove.
