Installing A Cell Phone Booster Underground - Hiboost 4K Plus Pro Review

I was recently offered a cell phone booster to test and review, and figured underground in a tunnel would be a pretty unique use case! This is the Hiboost 4k Plus Pro, which works with various mobile networks. The testing site is out at Sandland, where I've been helping to dig sandstone tunnels and build other projects for a few years now. We also have a weekend camping cabin made from an old zoo monorail at Sandland. In addition to the tunnel test, I checked the Hiboost unit's performance at the monorail for more of a "typical" use scenario.
