The Blonder Tongue CATV Modulator SAW Filter Channel 71from Blonder Tongue CATV Modulator SAW Filter Channel 71is an all-solid-state audio/video modulator that provides a modulated visual and aural RF carrier output on one specific CATV channel. The unit modulates the audio and video inputs and provides the requested RF CATV channel output for use in a CATV, MATV or SMATV system. The modulator accepts standard (sync negative) polarity video at a 0.7-2.5V peak to peak level from sources such as a TV camera, video tape recorder, TV demodulator or satellite receiver.

The modulator features a +55dBmV RF output level, and an IF SAW filtering for adjacent channel operation. All aeronautical channels are offset positive with a tolerance of ±5kHz as required by FCC 21006. All level controls are located on the front panel. The RF level control provides up to +55dBmV output. The video modulator control sets the depth of modulation for 87.5% over an input video level range from 0.7VP/p to 2.5VP/p. An audio modulation control permits adjustment for ±25kHz peak deviation of the aural carrier.

[CATV channel 71] Expensive but knocked out the hum coming from my cable. 5

[CATV channel 71] Much better picture than using VCR for modulator and Radio Shack RF switcher. No lines much better picture. I only use Blonder-Tongue for modulators. 5
