What kind of GPS antenna should I use with Telit GPS products?
It’s strongly suggested the use of an active GPS antenna. The power
supply is provided by the module (through the FT pad / connector). The
voltage level is just the same of the module VBATT (nominal 3.8V).
Telit GM862-GPS and GE863-GPS comes without a LNA inside the GPS module.
I hope that my hints will help you.

We should use the GPS inside the HE910 with an active antenna that receives Vant with the RF signal; is it possible to send in this chip the 3.3 V with the RF signal ?
Alternatively, have you some external configurations to suggest to mix RF and Vant signals?
There is an example in the HE910 Hardware User Guide doc page 53.
