When I first purchased the Drive Reach in June of 2020, the first cross-country drive started four days later.
The stubby antenna wasn’t enough for me so I upgraded to the RV antenna. at the time, when I purchased it, weBoost claimed it was good for 5G. I tend to disagree, these days it only says 4G on the model I initially purchased.
WeBoost 311230 Drive Reach RV Cell Signal Outside Antenna is the new 5G antenna included with new Drive Reach kits.
