GL-X750 with External Antenna?

If I add an external antenna to my X750, something like this:

Proxicast 4G - https://smile.amazon.com/gp/product/B01NBSLNJ6/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

Do I need to worry about the WIFI portion of the spectrum too? By using this external antenna do I lose WIFI 2.4 Ghz and 5 Ghz range/sensitivity?

Thanks

WiFi antenna are internal, the externals are 4G only.
