As seen on eBay, and it’s yours for about $15. Strange as this gadget may look, I actually see an advantage when it comes to range. A handheld firmly attached to your belt combined with an ordinary speaker microphone won’t translate into an optimal range. The antenna is just a few feet above ground, and the proximity to your body reduces efficiency even further.
That said, it looks weird, very weird. I can’t see myself walking around with it. Update: my reader’s comments reveal that the quality is very poor; purchase not recommended.
