Dyneema soft shackle as antenna insulator

[Brion Toss]

Hi there,
I understand what you're saying, but there might be problems, like that the uninsulated portion would be too close to the mast, unless you made a 4 foot shackle. So why not an all-Spectra backstay, with a portion of wire inserted in it? I've heard good things about that. Check with Colligo.
Fair leads,
