The DA-506BID video amplifier hubdistributes CATV
or antenna signals to 6 TVs. The has four short
run outputs (up to 75 feet) and two long run outputs (up to 150
feet) for maximum flexibility. The has a
broadband 54-806MHz amplifier and a 5-42MHz reverse
channel which is compatible with pay-per-view, interactive
cable and cable modems.

Herringbone patterns on several channels.
A wavy pattern on the TV picture is caused by one or more spurious
signals in the 6MHz reserved for that TV channel. These spurious
signals, or ‘spurs’ can come from several places. For example, a
modulator at channel 16 will interject a spur into channel 15.
But the prime cause of spurs is an over-driven distribution amplifier.
(This is also known as IM or InterModulation distortion.)
To determine if an amplifier is causing this distortion, an inexpensive
variable attenuator will allow you to perform this simple test:
Insert the variable attenuator before the amp. (If you have splitters
between the amp and TV, that’s OK.) By the attenuation,
you are the signal that reaches the amp. If you find that
the herringbone patterns disappear, then your problem is an over-
driven amplifier.
Causes of an over-driven amp:
1) Too much gain in the system. Use the variable attenuator to find a
setting where the signals are not noisy, and the amp is not being
over-driven.
2) Strong local FM signal. If you have a nearby FM transmitting
tower, you may need to install an FM trap before the amplifier.
3) Strong local TV signal.

If you have a nearby TV transmitting tower,
you may need a tuned filter to reduce this station’s signal. Often the
station management can supply filters for their neighbors.
Variable attenuators and FM traps are available at many hardware
stores and most electronic stores.
