I’ve been lucky enough to purchase 100 meters of Ecoflex 15 recently and the solderless connectors are awesome.
Available for Aircell 7 (RG213 replacement) and Ecoflex 10 (Westflex replacement) and this giant 15mm diameter stuff, once fitted they are completely waterproof.
My experience with all these products started with me laying down a few runs for my narrowboat earlier this year because I wanted a low RF leakage product. More recently, I’ve rebuilt most of my spare patch leads with the remainder of the Aircel and Ecoflex left over from the boat build. All my RG213 and Westflex has been relegated to tutoring and testing.
