Doing a little more research I found that channel 4 is at 69MHZ. Dabbling in antenna theory, if I was to modify an element or two on my current antenna what would be the ideal length they should be for that frequency? Or is there more to it than that? A full wavelength is 14.25 feet. These other antennas state db gain compared to a dipole. Is each company using the same length dipole for the testing?
