Are you interested in buying a second hand antenna? It is because of a budgetary constraints or you are interested in purchasing a kind of antenna which is now not available with the manufacturers. Whatever your reasons might be you should stop and think of these points.
Beware of jargon
Most owners or seller of old antennas who are in the process of looking for buyers generally use jargon to make their products sound better than it actually is. For example “HDTV/ High Definition” is a phrase which is used quite frequently to make the antennas seem like magical devices which will automatically give fantastic reception.
You should understand that TV signals have no way of differentiating these antennas from other antennas. Any standard antenna with all necessary features will be perfectly suited for your TV so don’t pay extra money just because the seller is trying to feed you a lot of jargon.
Know the signal strengths
The most important component to think of when buying a digital antenna for your home is the signal strengths of the TV stations nearby. All digital antenna owners will claim that their antenna is the best. However you have to choose an antenna which meets your requirement. If the signal strength is weak you will need to purchase a much bigger antenna. If you live in a city which has high concentration of TV stations then you can make do with a much smaller antenna.
It much safer to buy the antenna from a reputed manufacturer who happens to keep stock of old digital antenna too.
