Except for short range and line-of-sight applications your GCS is usually better off with an external RF box, even if it's a handheld or a wearable station. This helps evading attenuation losses on extended antenna cables and makes your operators' coziest location independent from the best RF position in the field. We manufacture rugged RF boxes for all sorts of applications and band plans, hybrid 2-3 band links and fully digital MIMO IP systems.
