Antenna tips and information for your neighborhood


Here are some tips from the National Association of Broadcasters for good TV reception:

1. Outdoor is generally better. Outdoor antennas have a better view of the transmitting station, with no building-induced signal loss. They receive less interference from other household electronic/electrical appliances, and they are less likely to receive reflected ghost signals from the building structure.

2. Higher is better. The higher an antenna is, the more direct signal it can receive from the TV transmitter, while at the same time reducing the reception of interfering signals from other household electronic/electrical appliances and reflected ghost-causing signals from other nearby structures. The higher the better, but any antenna should be at least four feet above the structure to which it is mounted, and ideally above the roofline.

3. Closer is better. If a position above the roofline is not possible, the antenna should at least be on the side of your building facing the TV signal broadcast tower.

4. Bigger is better. The larger an antenna, the more signal it receives. This is especially important on channels 2-6, where the longer wavelength requires a larger antenna in order to be efficiently received. Larger antennas also become directional which reduces ghosting caused by reflected signals coming from the side and the rear of the receiving antenna.

Once the type of antenna you need is selected using this guide, careful attention must be paid to its installation. While not difficult to install, antennas are sensitive to installation details. For wood-frame buildings where the antenna will be situated on the roof's peak, the antenna should be at least four feet above the peak. When installed above a flat metal roof, the antenna should be at least ten feet above the roof. For multidirectional antennas, allow for some mounting flexibility so that the antenna can be moved a few feet in each direction in order to obtain the best picture on all channels before a permanent mounting position is selected.

The NAB has an online guide that helps with everything from buying to installing an antenna.
