Dunestar 300-7 USED | 90 Days Warranty

The filters are 3-pole, top-C coupled. Hi-Q capacitors and inductors are used for tuned circuits. Filters are constructed on glass-epoxy PC boards. Inputs and outputs are at DC ground potentials. Aluminum Enclosure. Dimensions: HWD 2.0 X 6.0 X 1.75 Inches (including mounting flange).

Filters are intended for use with 200W PEP transceivers. This is not to imply a 100% duty cycle. For example, if you were to operate RTTY (100% duty) as much heating would occur as if you run SSB speech (50% duty) at the same power for twice that length of time. With compression, average power increases to 60-80% duty. CW average power is roughly comparable to speech. Insertion: Typical, 0.5-.7db
Rejection: Typical, 40db band-to-band
