TTGO T-Beam V1.1 case for big GPS antenna

cults3d

This is a remix of tpatrickwalsh's TTGO T-beam v1.1 (and v1.0) case, modified to fit the bigger GPS antennas for better reception. I have found that the bigger antenna is a must, as the smaller one is pretty much useless if it doesn't have a completely clear view of the sky, and it takes ages to get a lock when it inevitably loses it. The new slot is big enough to fit a GPS antenna with a 28db gain (with a 4mm tall ceramic element), it's one of the bigger ones, it can also fit the smaller ones. The 28dB antenna is quite convenient as it locks with plenty of satellites even inside, thrown inside a backpack or tucked inside the glovebox of a car! No supports are needed. I have also slightly modified the top "lid" with a small hole, so you can see the red LED of the GPS module. This way you don't have to wake up the display to see if the module has GPS lock. If it blinks, you're good!
