Heat sink for 3″ x 4″ compact (airborne) RDMS™ receiver. Does not require a power source.
It is important that the RDMS™ be kept within its specified operating range of -40°C to +70°C. At maximum bit rates, the unit dissipates approximately 20 watts. At normal ambient room temperatures, a small fan blowing across the top cover is adequate. Higher ambient temperatures will require more airflow and/or a finned heat sink such as this one on the cover.
