Hi,
this is my installation, portable but also weatherproof.
I used a cheap Omnitracs Antenna Unit (15€ via the …bay), threw out whatever possible, placed 3s Lion-Batteries (8.5 - 12.5 Volts) down under the copper board, added a DC/DC converter to +5 Volts, connected the Reach via 3DR Radio to the mobile, 3DR under the Reach device and its copper board. The 3DR antenne is a self made Magnetic Loop Antenna for 433 MHz (small but powerfull and no groundplane neccessary, RF power output can be adjusted and connection through two walls is no problem on my side). Reach’s WiFi antenna is facing up (in the forground). The GPS antenna is placed on a round 20cm Copper plate, not really properly fixed yet, but working well. There is only one ON/OFF switch and a connector to load the Lion-Batts.
WiFi connection is done via a mobile hotspot/router between base and rover (Huawei E3572). But…WiFi to the Base is not required during ‘normal’ operation, 3DR-radio is the link to the Rover…
