How do I aim an antenna for digital television
The HDTV content is available now through your TV antenna absolutely free of cost and directly through your airwaves. For pulling up these airwaves, you would need either an outdoor antenna or an indoor antenna placed appropriately. But, you cannot just place and point the antenna in any direction and expect it to work just the way you want to. Carefully aiming the antenna is vital so that it can provide the desired results. There are various websites such as FCC, Antennaweb or TVFool which can provide details as to which direction you would need to point the antenna. For those who reside just few miles away from a broadcast tower that is located centrally then they can go in for a omni-directional antenna and point it directly in the towers direction. Even though omni-directional antennas are considered to be less powerful but they surely can get you all the required channels that is present in your area.
Once you have mounted your antenna on the rooftop, the next step would be to actually aim or point it in the correct direction. There are resources available in the sites mentioned above that can help in providing details about the local transmitting towers. You can make use of a compass for aiming the antenna in the direction that has been clearly indicated by the online resource. Once it is done, you can scan for the channels. If you are satisfied then, complete the other installation process. However, if you feel that there are few channels missing then you can make certain adjustments by rotating the antenna in small five degrees’ increment. Each time you would need to carry out a channel scan. You may also go in for a rotor wherein it allows for making small changes in the orientation of the antenna without the need for climbing on the roof.
In case of an outdoor antenna, the narrow end would be pointed towards the broadcasting tower. There are a lot of people who tend to mount the antenna in the backward direction just thinking that the elements should be pointing away from the tower. But the main aim is to pick up as much as signal strength possible. Note that grounding the antenna is also important since you do not want the antenna to shift even with a small wind.
For those who live in apartments, wherein getting an outdoor antenna is not possible. Then they would need to go in for indoor antenna. This small and sleek indoor antenna can be mounted on the wall or a window. Using the same technique as the above case you would need to aim the antenna in that direction. Mostly indoor antennas are not suitable if you have weak reception signal in the area. Some of the indoor antennas also offer a powered option wherein with the help of a signal booster you can increase the signal strength.
There is a lot of information present on FCC or Antennaweb that helps in giving the viewers resources about where exactly the direction of the antenna should be. All you would need to do is follow those guidelines so that the placement and position does not lead to any problem in future.
