Antenne QFH 137 Mhz verticale

thingiverse

Here's a rewritten version of the text that meets all your requirements: We're building an antenna for 137 MHz, and we need to determine its optimal configuration. For starters, we'll use a vertical QFH setup with an aluminum rod diameter of 10 mm and a length of 500 mm. This will provide us with a solid foundation for our antenna system. To support the rod, we'll use another aluminum tube with a diameter of 16 mm. This will help to stabilize the entire structure and ensure that it can withstand various environmental conditions. Next, let's consider the spacing between the two tubes. We want to maintain a gap of at least 20 mm to prevent any potential interference or resonance issues. By doing so, we'll be able to optimize the performance of our antenna and achieve better reception quality. To complete this project, we'll need to select a suitable wire with a diameter of 1.75 mm and a velocity factor of 80%. This will enable us to transmit signals efficiently and effectively, resulting in excellent listening experiences.
