can i have more than hundreds of channels when i use this? pls tell me.
-
@daiatlus79 Digital TV uses the same channels (and thus the same wavelength) that was used by analog TV.
-
@ChempediaTV Read my comments to @daiatlus79. I make my living maintaining transmitters that deliver that signal you are receiving so I do know something about it.
-
@daiatlus79 Yes of course it depends on the wavelength- but we weren't talking about wavelength- We are talking about form of modulation- and for any given frequency the antenna doesn't care crap if its NTSC analog or ATSC digital- its just RF to an antenna. And to clarify things further- while it's RF it IS an analog signal- modulated in 8-steps of amplitude. It doesn't become a digital signal until it is demodulated by the TV set.
-
@nakayle antennas are dependant upon the wavelength of the signal you are trying to pick up. length, spacing etc are all important!

woo familyguys on!

On a satellite dish the whole thing isn't the antenna just the little grey things on the end of the rod That points towards the dish. What happens is the signal reflects off of the dish into the little grey thing. ( I don't know what to call it,) u r pretty close tho

@shartne he forgot it was to hold the think down.

Not sure what exactly it is you have made here, or why you assume that it even works. Your "dish" is not parabolic, is not sized correctly, is at the same potential as your "feedhorn" and in all reality is just a large signal plane that happens to work better than your old setup. The taped magnet you tried to make a toroidal wound inductor on is not helping you. This is not an antenna.
