The idea of swapping the shark fin antenna for a screw-on dual antenna seems reasonable. This option avoids the visible issue with the included antenna, which tends to move or fall when disturbed.
Yes, dual band antennas are perfectly fine to use. They work across multiple frequency ranges without needing physical modifications to your setup.
You have the option to swap them for coat hangers. This might affect performance. The method antennas use involves adjusting their size to match a specific frequency range. In the 80s, stub antennas gained popularity because they could be made by winding many thin wires into a large coil. This allowed compressing a long antenna into a compact space. However, they required precise dimensions; using an incorrect length reduces effectiveness.
The concern about dual-band antennas damaging the card isn't well-founded. They don't harm the internal components; any potential issues are usually related to signal quality or interference, not hardware destruction.
It should function but you might face some minor compatibility issues. The Asus antenna is built for 802.11ax WiFi via its built-in card, with the antenna shape fixed in firmware. The rubber duck antennas from an 802.11n card have inconsistent spacing, which can disrupt MIMO performance. While it may go unnoticed, this setup isn't ideal for your WiFi card and could harm its longevity over time. It's also not very effective for your existing radios and might wear them out faster than expected. Be honest, these are standard consumer antennas, not high-end ones like Duga-3.
Based on my observations, plastic covers act as transparent shields for antennas, often appearing as simple covers without any visible structure. The material inside, like a shark fin, isn’t always obvious. If you dislike the appearance of the plastic, you can easily remove it and swap it with another shape that fits better. The shape you choose will depend on what’s inside. These covers help maintain a safe distance for radio signals—metal near antennas can become harmful at close range, but a 1/16” thick plastic barrier usually provides enough protection. This is why some concerns about cell phones and cancer are misunderstood.
