with detachable antenna can search wireless network much better, and more expensive, only 50 cents.
Besides — detachable antenna with standard RP-SMA connector that allows you to connect another antenna or an extension cable.
The only weak spot USB Wi-Fi 5dBi
is quite fragile body, so amplified antenna is best connected via an extension cable.

Even with standard 5dBi antenna this adapter scans noticeably more available networks in an apartment building than a conventional Nano Wi-Fi
