Excellent performance in a small package for ENG and DSLR video production is the purpose and intent of the LR receiver design. Tracking front-end filters block interference from high powered RF signals on nearby channels to preserve the extended operating range. RF spectrum scanning displays accurate results on the LCD to make finding clear spectrum quick and easy.
