HDTV Antennas

An antenna originally designed to work for the old analog TV stations should be OK for use with modern high definition and digital TVs

In principal, they should work the same but replacing your old aerial could bring advantages when tuning into the transmitter for other reasons:

• Gain
  Measures how much signal or energy the antenna will collect with modern high gain tv antennas helping to pull in more information
• Beam width
  Gives a measure of how focussed an aerial is with a wider beam making it easier to capture a signal
• Bandwidth
  Different stations are transmitted at different frequencies and bandwidth gives a measure of how gain varies with signal frequency
  If the antenna has too narrow a bandwidth it may be good at receiving some channels well but fail to give a good picture on others

Don’t be fooled by claims of digital aerials but do consider upgrading to a digital compatible aerial that can help provide a better picture thanks to improvements in aerial performance
