While that certainly allowed us to make more direct comparisons between products, it really didn't provide much context for the product category of indoor HDTV antennas as a whole.
Be sure only one antenna is being moved at a time! After the initial link has been established, take note of the Ideal Power reading. This is the signal level that you should be able to obtain based on distance, antenna gain, and output power.
Antennas may seem to be a mystical art. Unlike many electronic devices, any change in nearby materials or dimensions can affect antenna performance. Trying to build a published design does not guarantee results. Testing an antenna design is necessary, tuning is usually required, and there are pitfalls along the way.
Large-dish satellite antennas pick off unencoded or encoded signals being beamed to Earth by satellites. First, you point the dish to a particular satellite, and then you select a particular channel it is transmitting. The set-top box receives the signal, decodes it if necessary and then sends it to channel 3 or 4.
