Signal Strength Present At The Television; Connecting To An Over-The-Air Antenna - Dish Network DP512 User Manual

Signal Strength Present at the Television

The attenuator provided with the satellite receiver will limit the signal present at your television set to below the FCC
signal strength limit of 75.6dBuV. If you choose not to install the provided attenuator, you must ensure that the signal
strength present at the TV set does not exceed 75.6dBuV.

Connecting to an Over-the-Air Antenna

In order to receive local broadcast channels, you may wish to install an off-air antenna into your TV distribution
equipment. When installing the off-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 text please visit www.FCC.GOV.
