The specific frequencies for the 10-meter band in other regions are unknown. However, according to the schedule, the North American West is open from 7:00 AM to 10:00 AM, and Europe Central Asia is open from 12:00 PM to 8:00 PM. There is also a chance to connect with South America in the evening, and sometimes even the Caribbean or Eastern United States. Generally, the best time for communication on the 10-meter band is from October to April of the following year. The closer it gets to summer, the worse the DX (long-distance) performance becomes, but in recent years, with peak solar activity during the summer, it has been possible to achieve some DX. In terms of overall performance, the 15-meter band tends to be better than the 10-meter band (especially in summer). That's why major contests like CQWW and CQWPX are held between October and April of the following year, including the ARRL 10-meter contest, which is held in December. The timing of these events is related to seasonal propagation. However, WPXCW is held at the end of May, when the 10-meter band has already deteriorated, which I find frustrating. The height of the Yagi antenna above ground can affect the number of side lobes. Side lobes can help you connect with areas that require a high angle of elevation (such as the Middle East and Region 0). You can choose the appropriate height based on where you want to connect. I hope you have a great time!
