TUM714 Block Upconverter for conversion of "T" channels
The R.L. Drake TUM714 block upconverter is designed to receive the block of CATV channels in the range of 5 - 54 MHz. (channels T7 - T14) and convert those signals to EIA channels 7 - 13 and channel 23. Input and output levels as high as +30 dBmV may be used, nominally with unity gain. The typical application for this device is to receive a remotely originated channel and convert it so it may be fed into a video recorder or demodulator. Minirack packaging allows this product to be intermixed with other related products in a 4 slot or 12 slot configuration.
- An inexpensive method of returning remotely originated programming to the headend.
- Upconverts 5 - 54 MHz. by 168.25 MHz.
- Usable at high +30 dBmV input level.
- Suitable for use with digital or analog signals.
- Modulators, demodulators, stereo encoder, rack mount and power supply sold separately.
