If they match the same style, it's okay—but expect reduced performance.
It will function, but you might encounter some minor compatibility issues. Your Asus antenna is built for 802.11ax WiFi via the built-in card, with the antenna shape programmed into its firmware. The rubber duck antennas from an 802.11n card lack a uniform spacing between them, which can disrupt MIMO performance. Still, this effect may go unnoticed. It also tends to be less efficient for your WiFi card and could shorten its lifespan, though it shouldn’t cause major problems for over two decades. Honestly, there’s no assurance the shark fin design offers significantly better RF characteristics—it's just a modest consumer-grade solution, not something like Duga-3.
Would a UHF device suit VHF applications? Could an SHF unit perform well with VLF? Unless you're focusing on compression and coding variations—and the transmission wavelength stays constant—then no, a design meant for one frequency won't deliver good results (if it functions at all). The same principle applies to radar jammers; they need to match the specific wavelength of the system they aim to disrupt. Other technologies still detect certain signals. We lost an F117 due to several issues, including older radars using longer wavelengths that weren’t built for stealth tech; the F117 wasn’t meant for those frequencies. Likewise, chaff must be adjusted in length based on the threat level or multiple lengths tailored for different dangers.
Here, both antennas operate in the 2.4 GHz and 5 GHz ISM ranges using a simple dipole or array design. The SWR is likely higher for each individual antenna than the included unit, but it probably won’t cause harm from half a watt of power in the microwave spectrum. Note: Any metal object can easily transmit and receive RF signals, but you must manage the SWR to avoid damaging the radio when transmitting. Solutions include using an antenna tuner, selecting a resonant antenna, or limiting transmitted power so reflections don’t harm the device. Antennas tuned to specific frequencies tend to perform better, though any setup will work—AM radios, for example, use large antennas with substantial power and still function. For more details, refer to the ARRL Antenna Book. The challenge here is that both options feature four dipole arrays—two for 2.4 GHz and two for 5 GHz. With a single integrated device, this setup is standard, whereas two separate units are less common. The difference matters due to distance and orientation from the transmitter. Understanding these factors helps determine if spatial multiplexing or other techniques could help. On WAPs with external antennas, firmware can detect and adapt to these conditions. This may affect performance in @Fair Trial, but the outcome depends on the specific WAP, its firmware, driver settings, antenna positioning, and internal design. It won’t damage anything if tested properly.
In most situations, this holds true except for a few rare scenarios.
Typically placing the router directly behind the PC ensures minimal signal drop through the cables. It also helps adjust for antenna orientation without needing them set up vertically, since they aren’t fixed for that purpose.
