Hello again every one. I just need a bit of checking up on my work, though I'm fairly sure I know the answer. Still, any input from someone who has tried already or just knows the answer would be useful to me. Thanks.
I want to directly connect a 802.11g USB WiFi dongle to a custom antenna in a way that's as loss-less as humanly possible, as well as cheep and repeatable. I figure that a short piece (>3 inches) of your standard Red Blue Yellow TV Audio/Video cable would work great since it's diameter is quite narrow and it is actually coaxial cable. So it should have less dielectric loss than TV coax at this frequency right? But... I *AM* aware that it is not the perfect cable to be using really. I'm just not 100% certain as to how much practical attenuation it's going to have. If it is no good like this then is it maybe possible to make a certain length that will resonate or otherwise work perfectly? Or some kind of impedance matching circuit? Or would it be better to use something like Sat TV coax? In the end I *COULD* always steal a length of legitimate WiFi coaxial out of a laptop If I had to. It doesn't really need two antennas. But I would rather not as I'm sure having both helps.
So correct me if I'm wrong, But I'm fairly certain that it will work with almost no loss with the A/V cable setup kept short as I stated above. And at the very least the enhanced antenna will make up for it by leaps and bounds.
Thoughts?
