I posted an idea i had several years back and don't know if anyone tried it or not.? My thoughts were to use braded wire (like used to hang picture frames ) and make up a tow cable to replace the plastic one and solder a wire to it and drill a small hole under where the cable lays and run the wire through the hole and attach to the board and use it for your antena.Kill two birds with one stone...

P.S. Some of that type wire looks just like a small cable in appearence.........Hide your antena in plain sight...no obstructions...
I think you could paint it and it would still work great...?

For what it's worth...
