 |
|
Does anyone know whether oxidation on an aluminum mag loop surface reduces performance over time? I have a Pixel Pro-1B receive-only non-resonant amplified loop antenna that has been in the weather for several years.
Thanks, Ron

| If the aluminum oxide is resistive, it would degrade the antenna performance. However, after a quick search on the conductivity of aluminum oxide it still looks to be a decent conductor, so I don't suspect there is degradation |

| Aluminum oxide, also known as alumina, is an incredible insulator and low loss dielectric. But a thin surface layer should not have much effect on your loop. |
