I recently obtained the super-cool Sark110. As others have mentioned, the connector seems the potential weak point. Trying to twist it around to read while hanging off the end of RG-8 seems like a recipe for repair.
With help from KA4VBF, we 3D-printed a solution. It holds the MCS-SMA at the hex neck. It wraps underneath and screws in with longer, replacement chassis screws. It is designed to support the rubber case although a little exacto work is required on the rubber.
Attached are 3 photos to give you an idea how it works. Also attached is the STL file should you want to have a go. If you'd like the SCAD let me know.
Note that the 3d print might require a little exacto cleaning up.
I replaced the chassis screws with M2x0.4x14. Unfortunately I had to buy 100. If you want to send me an SASE I'll send you a couple.
