This list is selected on the basis of the channels covered only and quotes the appropriate website’s antenna gain.
The higher the number of dB the larger the antenna, the more sensitive and more directional it is. It is also more expensive. The advantage of getting gain from the antenna rather than an amplifier, is that the antenna becomes more focussed thus rejecting delayed signals and interference sources. Amplifiers can become overloaded which antennas cannot. Thus amplifiers can make reception worse.
If the antenna signal is too strong at the receiver, a low cost attenuator can be used. The advantage of this method is that any interference picked up by the cabling is also reduced.
The antennas below are for prime signal areas. For more sensitive antennas use the band 3 vertical recommendation and the band 5 horizontal recommendations. They can be combined in a U/V diplexer or a masthead amplifier.
