so if I am broadcasting at 1200 AM... AM is in Khz, so 1.2 Mhz
wavelength=300/1.2 = 250
250m ?
Even 1/4 wave would be a long antenna... 62m
The transmitter I use has a coil prior to the antenna, I understand this helps reducint the required antenna. I optimized the output using a scope and have a good signal, but only for about 10 ft, after that there's an added noise in the background that seems to be due to the signal being too low at that point. I'd like to get about 50-60 ft.
would I be able to prevent that with a longer antenna on the receiving end?
How do I tweak the trasmitting antenna to get better distnace?
