Topband: Tensioning of RG58 coax for 2-way Beverage

[Tracey Gardner]

I have a follow on question from my non-invasive tree attachment question.

I am running RG58 through a hedge with the intention of using it as a 2-way 
Beverage.
I am scratching my head as to how to attach some poly rope close to the ends 
of the RG58 to enable it to be lightly tensioned.
I could use a fleeting cable grip if I could find one small enough.
If it was normal stranded wire I would just use duplex cable grips and an 
insulator, but as it is coax, I don't see that as an option.

All suggestions will be gratefully received.
