The 3271 series of deletion filters attenuate the entire channel spectrum from video carrier to aural carrier to allow reinsertion of new information without interference. The 50 dB continuous suppression from video carrier to aural carrier has been found more than ample for reinsertion. Attenuation drops sharply at channel edges to preserve upper and lower adjacent channels. Models 3271Sub-T7 to T13 and 3271AA -2 to 6 are temperature stable at 20 to 120 F.
All models are at AC/DC passing. 1 amp Max.
