Any good replacement antennas for the AX 66 that will improve

signal strength ? Do all 3 have to be replaced , or just 1 or 2 , mostly for the 5ghz band .
Thanks .

What I've seen people do is they replace the middle antenna with a directional one, and keep the omnidirectional antennas for the two others. That way they can get both good overall coverage 360-degrees, and the directional one can be aimed at the "dark spot".

If going with omnidirectional replacements, then replacing all three would probably work best.
