Eight’s Consumer Guidelines for Digital TV Viewers using Antennas

With the digital transition, Eight switched from UHF frequency to a VHF frequency. If you are using an indoor or outdoor antenna, please check to see if it is UHF only or UHF/VHF and that is oriented properly. Some of the “digital” antennas are only UHF antennas. For “rabbit ears” type antennas, both antennas should be extended all the way. Also, the antenna should be pointed at South Mountain ― the two “rabbit ears” should be extended in a “V” shape, with the area inside the “V” perpendicular to the television transmitters on South Mountain. For example, a viewer in Mesa would have one antenna towards the North and one South. Viewers in north Phoenix would have one antenna to the West and one to the East.
Amplified antennas can also cause complications, especially for viewers residing close to South Mountain (within approximately 20 miles). A simple “rabbit ears” type of antenna can usually solve the problem.

Converter boxes
If you plan on keeping your analog TV, you will need a converter box. A converter box is connected to your TV much like a VCR. You designate a specific channel on your TV set, and then use the remote control of the converter box to switch between the digital channels.
A converter box requires an antenna (as an input source for television signals). Your current TV antenna should work fine for receiving Eight's signal with a new converter box (test it before you buy a new antenna). Sometimes moving your antenna to another part of the room can improve reception.

If you use an antenna in Maricopa or Pinal counties, you will have to rescan the channels on your digital TV set or converter box. If a digital channel disappears, remember to rescan. You might also have to unplug your TV set or converter box for several minutes to allow the system to reset prior to rescanning. Rescanning for channels is like rebooting your computer. Check your owner’s manual. Many manufacturers offer the manual on the Web.

Central and Northern Arizona
Viewers in parts of Coconino, Gila, La Paz, Mohave, Navajo, and Yavapai counties will continue to receive Eight as an analog broadcast signal through a translator station (or repeater transmitter). For Eight viewers in these areas, a digital TV or converter box is not a requirement. Those who purchase a digital converter box should request a model with analog pass through (also called RF pass through). This feature will allow for both analog and digital channel reception — allowing viewers to receive all channels available in the area.
