The chart above represent a view from the top of the coverage and range of different antennas. The range estimates are based on the used of a 200mW Vtx. Numbers are a bit on the conservative sides too. As I said in previous articles, if you switch to a 800mW Vtx, you can double all ranges figures. I also added range at 90deg. off beam, in other words, the range completely off the side of where the antenna is pointing. Note that the numbers for the MX series antennas are more accurate as they are especially designed to be used at such high angle.
