Problem solved for $13.99
After trolling the net, I finally found the ideal solution for my problem. It's a 6ft lead that plugs into the back of the ZX-700 and has a small half sphere ~1" diameter on the other end which is the receiver. The receiver has a sticky pad on the back, and I have mounted it just below the TV. Reception is great and the ZX-700 hasn't missed an input from it yet.
