I suppose it should really be 'digital compatible antenna' but yes there is very little difference but even a small difference in the design of a yagi can effect the gain, tuned frequency, bandspread and front to back ratio.
[edit] Something the OP has to remember is that digital signals are more susceptable to breaking up on lower signal strengths than analogue due to the nature of the signal |
Unfortunately, the word "digital" is often used to justify a higher price. I'm stunned when I look around the rooftops nowadays. Some of the aluminum creations around wouldn't look out of place at a modern art exhibition. The basics are simple. Almost all TV aerials are based on the yagi principle(directors-dipole-reflector). You can only add a certain amount of directors (elements) as they become less efficient as you move away from the dipole. By the laws of physics, these elaborate designs work only slightly better than their bog standard yagi counterparts with straight rods. More money, weight, wind resistance, who needs it.
