3. Configuration & Operation
3.1 Why Cable Compensation?
All cables attenuate (reduce) the high-frequency components of the
video signal that is being transmitted. The longer the cable, the more
signal loss. If not compensated for, this signal loss will result in blurry
and smeared images.
The image quality depends on the resolution and level of detail in the
image. The Hall Research URA series of receivers has one of the
most precise and complex equalization techniques in the industry and
allows full recovery of the original signal’s bandwidth.
It is best to make this adjustment using a test pattern that is designed
to depict and exaggerate this effect.
Some Hall Research senders may have a built-in test pattern
generator. If your sender unit is equipped with this feature, simply
activate it on the sender. Otherwise, you can connect a PC to the
source and display a test pattern. You can point your browser to

for an image that allows one
to adjust the compensation and to evaluate the amount of color skew
in your setup.
The table below lists the recommended maximum distances from
