A stereo-audio video limited range low power RF transmitter to receiver system is provided transmitting signal from a video cassette recorder (VCR), satellite converter, TV camera, cable select box and a TV receiver/monitor, or VCR, utilizing a wireless signal path retaining signal quality normally associated with conventional wiring. Two-channel stereo-audio is passed via two independent audio channels matched to selected video channels for combined short range RF transmitter to receiver transmission to one or more television sets and/or VCR sets in different rooms, with at times display and/or recording simultaneously the same transmitted program from the transmitter of the system.

Limited range stereo-audio video RF transmitter to multiple receiver

A noise frequency and vibration absorbing mount is provided for microphones, particularly highly directional sound-gathering microphones, that, while achieving highly efficient reduction in the transmission of noise frequencies and vibrations, maintains directional alignment with the camcorder or camera, binoculars, rifle scope or whatever other equipment it may be mounted on regardless of directional change movements imposed on equipment mounting the microphone. The noise frequency, vibration absorbing and directional change stabilizing mount includes a hollow accordion pleated resilient material four walled enclosure fastened at its bottom to a mounting plate having two inside to outside small air flow dampening openings therein. The accordion pleated resilient material four walled enclosure is in rectangular elongate form in transverse planar cross section and is mold formed with a like density resilient material top connectable to a microphone and circuit case mounting connect member with the combined microphone (or sound and vibration sensitive device) case enclosed circuit and mounting structure having a combined weight in the two to five ounce range.
