You'd effectively creating a multipath generator with this setup, which means you have the primary signal, then a couple microseconds later, a reflection that is probably 20db under the main signal.
No disagreement that the yagi thing you pointed out would work better.
That said, this is a MIMO router, so that may change the modulus on the multipath problem.
- arghwhat 9y agoA reflection with just 1 microsecond delay would require a 300 meter reflection path (e.g. 150 meter to/from the reflector). I think you might be thinking of multi-path propagation within the context of long-distance communication (e.g., a HAM QSO). A regular home Wi-Fi network is already a complex multi-path system, as the primary propagation mode is reflections from walls and ceilings, leading to plenty of self-interference with many hot- and cold-spots from constructive and destructive inteference. We are at most introducing a few stronger reflections in an already extremely reflection-heavy environment. The big question is whether it does any good, either through attenuation or gain. As for MIMO, I must admit to not knowing much about it—I know it utilizes spacial separation to increase bandwidth, but I do not know much of its actual implementation, and thereby weaknesses.
