interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.

ONNECTING TO AN
In order to receive local broadcast channels, you may wish to install an over-the-air antenna
into your TV distribution equipment. When installing the over-the-air antenna, you must be
careful to meet certain FCC regulations.
There are many devices that allow you to connect your antenna to your in-home distribution
system such as splitters, and amplifiers. The FCC requires that the isolation between the
antenna port and the network port of your system meet the following:
• 80dB from 54 MHz to 216 MHz, at least
• 60dB from 216 MHz to 550 MHz and at least
• 55dB from 550 MHz to 806 MHz
Measuring the isolation of a device requires specialized equipment. In most cases, it is easier to
purchase a splitter or amplifier with the correctly specified isolation from your local satellite
television retailer. The above requirements are extracted from 47CFR15.115. For the complete
