1000 meters is a stretch for that. you can try to add extensions to it, but still, 1000 meters is a long way. i will say this, i noticed there are two other frequencies on the unit, still UHF range, but as you go lower in frequency, the wavelength becomes longer, and information carried on the wave may still be interrupted, but has a bit of a better chance to make it. This is not saying that using the lower end of that units frequencies is going to make it happen, just a bit of knowledge.
