al of VCR, satellite receivers, Security camera, ect. to a user selected TV channels. RFDM-3 is a 3 channel input Mono Modulator intended for non-adjacent placement of modulated channels in any channel free area of the UHF band or CATV ULTRA band. The Agile design provides maximum flexibility.

*Compact design for easy installation

Note: These are analog modulators. They will modulate on to analog UHF channel. If you are using these with a cable system you should be OK you just need to find an unused channel or block some out with a notch filter then set your TV's for cable input. If you are trying to use the modulator on an off air system how well it works will depend on the TV's in the system. If ,like some of my TV's,  the tuners will accept digital and analog and lock them all in when it scans or let you add analog channels you are all set. If , like some of my TV's , one tuner input runs the digital tuner and the other is for the analog then you will need to use a splitter to get signal to each input and choose analog tuner when you want to watch channels that are from the modulators.

Devices.

Note: The stereo dubbing cables are not included In the RFDM-3 and you need to buy   necessary quantity of dubbing cables depend on number of devices you plan to modulate.

5. For channel selection,   it is required that a channel higher or lower  be skipped from any UHF off-air channel. This is to avoid off air channel interference. Example: Channel 23 is a local off air channel, for channel selection, the channels 22 and 24 must be skipped. Note: this would also be required when using the Ultra band selection. Example: UHF channel 17 would be channel 68 in the Ultra band.
