Web21 de mar. de 2024 · 1 Answer. Sorted by: 1. With a 9:1 endfed, you don't want it to be a 1/4 wavelength at any band. The reason for this is because the 9:1 transforms your roughly 400-900 ohm load into something close to 50 ohms. If you want more antenna length, somewhere around 53-59ft should work well. Share.
