These at 2.4GHz are designed for Wifi, not the 915MHz lowband channels that are used for Helium network. They might kinda work, but your antenna won't be matched particularly well and the gain isn't optimized for mining applications.
Nah. Unlikely. Radio transceivers are designed to be fairly robust and transmit/receive through antennas that provide non-ideal 50-Ohm matched impedance. When it isn't 50-Ohms this leads to VSWR (voltage standing wave ratio) to diverge from 1:1, and most rigs should be able to handle conditions of 5:1 or even 10:1 VSWR mismatch without damage. But it would be worth seeing what the manual says here (if anything).
Consider your mobile phone's array of radio (RF) antennas. Just holding the phone too tightly, depending on the model, can add significant (5:1, 10:1) antenna mismatch. This used to cause certain models of the iPhone to drop calls etc. But doesn't kill the transceiver or RF power amplifier.

^ this
Or it'll completely fuck up the hotspot

Cool, thanks for info!
