    Theory of BiQuad Antenna Design (now a digital TV channel question)

    I built yagis and biquads antenas lately,my question doing researches on it and nothing,is when i use any driven or director elements ,its normally cilindrical elements,what if i use squared or rectangular elements,what would be reaction of it.i had problems with that all the time whith yagis...

    Theory of BiQuad Antenna Design (now a digital TV channel question)

    Hi there again,thanks for the info.the channel displaying is nothing but a logo and reference,not rf channel.i scanned a channel no. 4 but the rf channel is on 47-1 and i programed directly. To channel 47-1 and it takes it directly to channel 4-1 automaticly.now i get the point,most scanned tv...

    Theory of BiQuad Antenna Design (now a digital TV channel question)

    Im in the region of United States and mexico and checking the channel frequency for digital tv channel 4 witch falls around 70 mhz and i used a dipole and yagi on that frequency and i get fair signal,but if i use a biquad calculated for uhf 589 mhz on channel 4 ,the signal is much better.it...

    Theory of BiQuad Antenna Design (now a digital TV channel question)

    Here is a much clearer question.channels 2 to 6 in analog is on vhf low but on digital,channels 2 to 6 could it be on uhf or vhf high?i checked a listing of frequencies on line several ways and it shows that same one as analog standard but in my experiments it doesn't make sense.

    So in analog tv channels, what ever channel you tuned had to be a certain frequency asigned,wich i was awear of,but in digital i thought that in the convertable box,the channel you tuned it would have to be a certain frequency were ever you go,but i guess its not like that.so digital channels...

    Theory of BiQuad Antenna Design (now a digital TV channel question)

    How is it that a biquad i made for tv uhf band 586 mhz calculated receives better signal on vhf low tv channels 2 threw 6 rather than i yagi or dipole for vhf low on digital tv.it seems like all the tv hd channel would be in uhf.i did this experiment in analog and it does matter the length of...
