Skool me on cell phone boosters and install tips, please

We have a campsite way way up north where we work from in the summer. Installed a 40' antenna (extending pole with guy wires) and a highly directional antenna, coupled with a SureCall booster and the indoor antenna. Omnidirectional and Yagi didn't work well for us, this antenna (Link) has to be pointed very precisely, but delivers up to 15 db gain (in addition to the booster), which is exceptional. We started with 1 bar signal and now get full bars and roughly 20 Mbps internet speed, which is fine for remote work.
