My question is: will this antenna, the loop stick antenna mentioned above, boost the signal coming from my "transmitter" or will it just allow my reciever to pick up the signal easier? or in other words how will this antenna help me? No one can tell how anything can help if you don't tell us what help you need. Being able to receive inches away speaks to an accomplishment, not a problem. If you want to receive miles away, then the comparison between what is accomplished and what is desired reveals the problem. sorry if i wasn't clear enough before. i just thought you would understand what i was talking about. You never really "talked about" anything when the sum total of your correspondence barely exceeds a half dozen lines up to this posting. Now, we can all presume an intent, and that intent goes counter to what is allowed by law, and that is long distance communication on commercial frequencies by an unlicensed station. The law is exceptionally clear as to how much power is allowed, into how large a radiator, for unlicensed stations (such as yours). The long and short of it is that without exceptionally good reception gear, that distance is rarely more than across the room, or within a block. Clearly, even these distances vastly exceed your current accomplishment of a few inches because you could invest little more effort into doing it with a modulated LED across the room. TV remotes do this a billion times an hour world-wide. Even with the allowed sized radiator, it is pathetically inefficient (which is the intent of the law). The name of the game is called matching, and a XTAL oscillator is a poor power source. However, all of this is strictly window dressing unless the whole scope of your Science Fair project is limited to building a working transmitter. If so, you need to formulate better questions. If not, you are spending too much time when you could build a Ramsey Kit in an afternoon and get on with the grist of the project. 73's Richard Clark, KB7QHC |
