ya I already have a color t.v and on of those crappy t.v antennas how can I amplfy the antenna to get more channels? should I try alummuim foil?
Wow, you got all kinds of answers.none of them very goodYou need to spend some time looking at The Radio Ameteur's HandbookIn there are pages and pages of antenna theory and construction articles for various antennasMaterials you will need: Plexiglass for insulators aluminum tubing for elements Aluminum tubing or a long wood pole for a boom to mount the elements upon300 ohm ribbon cable for feedline, or 75 ohm coax feedline depending upon the type of driven element you choosea folded dipole requires 300 ohm feed a half wave dipole requires 75 ohm feed I would suggest you look into the idea of a 3 element beam antenna.not to hard to build at homeyou need to determine what channels the antenna is going to work on - that determines the length of the elementsThe driven element is the one that is most criticalEach Television Channel has a Frequency (Sound and Picture)Look this up on the Internet using a searchThen use L 468/Freq in Mhz to get the element length for a half wave dipoleThe director should be 8 percent shorterThe reflector should be 8 percent longerUse some of the spacing information in the handbook to get a rough idea of element spacing in inches.
