G4AR Gateway external antenna use
I've been trying to use the G4AR gateway with my external antennas but see little improvement when connected. I have been using another provider's cellular modem with a T-Mobile sim (so same tower an...
I'm no expert, but the FCC regulates power outputs for about everything...WiFi, Bluetooth, CB radios, etc., because of concerns about interference with your neighbors, particularly in dense areas. If there was no limit, you could drown out your neighbors.
It stands to reason that Gateway's radio amplifier is "sized" to the internal antenna array, so that the radiated power is at whatever the spec limit is. If you put on a more efficient antenna, then the radiated power will go up and over the limit. In other words, the radio amplifier should be putting out less power when using this new wonder-antenna to maintain the limit on radiated power. As I understand it, the TM app requires you to set a "switch" to enable the antenna ports (I could be wrong)...it may be that this "switch" not only enables the ports, but cuts back on the power of the radio amplifier.
None of this may be correct. But it would explain why the new antennas don't seem to be doing much. A potential hack would then be to by-pass the TS-9 connectors, don't enable the switch, and connect to the internal antenna connectors directly.
Again, this is just morning coffee banter...I have no direct experience with any of this.
