With these antennas; how does the signal flow through the glass?

Is it also possible across other bands; like 2.4GHz Wi-Fi signals?

Specifically tuned for the 4G NextG / 3G spectrum for optimum reception performance. Operates at 5db gain. Suits: All handsfree car kits / cradles that require external antennas.

GSM 900MHz / 1,800MHz
3G 2,100MHz
NextG 850MHz
FME Connection
Whip 1 Gain 5dB
Cable Length 5m

  • \$\begingroup\$ No. It's near field coupling at the base of the antenna pod. \$\endgroup\$ – Janka Oct 10 '16 at 19:29
  • \$\begingroup\$ For lower frequencies, magnetic coupling is probably more efficient than that very small-value capacitor with a wide plate spacing (through the glass). \$\endgroup\$ – Richard Crowley Oct 10 '16 at 20:15

The glass acts like the dielectric of a capacitor, with the plates being the structures stuck on opposite sides of the glass, I think...
