You should know that stock all channel tv antennas are cut on a "V" or
hyperbolic shape. Each element is electrically connected to each other. This shape simulates a solid plate antenna cut into two triangular pieces and is not a very efficient antenna. If you make a dipole antenna cut to channel 57 you should increase you receive signal. If you make a yagi antennas cut to ch 57 you will increase your signal in accordance with the design of your antenna. Remember all yagi antennas fabricated to the same specifications no matter the frequency will exhibit the same gain, more or less.

I'm making a yagi antenna for channel 57, I'm thinking of using 14 copper wire for dipole element and the 14 gage wire for reflector and director elements, just ot see if I can get it to work better. actually thinking of use the channel 69 to make the antenna to cut the peices of antenna. Will I be able to pull 57 easier. Presently have a 4 elemnet bowtie Delhi uhf antenna. want to play with a yagi before buying one, to see if it works better, with out dropping the cash. would stacking another one on top of the 4 bowtie on top of the present one give me anymore gain???? theres no refector on mine. I'm half way in between 2 areas buffalo and toronto transmission towers. Not being a ham I know you have to tune the antenna for impediance I guess. Can I use a 300 to 75 ohm transformer or how would I find the impediance of the antenna If I made it from 14 gage house wire. What if I use 300 twin antenna wire for the active element and 14 gage wire for the refectors and directors? Are the reflectors and directors NOT connected to the active element. I would appreciate any good sites on building your own TV antenna or any info. in this area. talked to alot of antenna tv shops and I get no help, so I decided to trry and build a experimntal unit before droping the cash on another uhf antenna. |
