Select Models pass up to 1 GHz without an external
passband extender.
The series of deletion filters attenuate the entire channel spectrum
from video carrier to aural carrier to allow reinsertion of new informa-
tion without interference. The 50 dB continuous suppression from
video carrier to aural carrier has been found more than ample for rein-
sertion. Attenuation drops sharply at channel edges to preserve upper
and lower adjacent channels.
All models are at AC/DC passing. 1amp max.
*Can be extended to 1 GHz with external passband extender.
