Good, powerful antennas for mobile use. My company uses them on their ships - we mount a bank of 8 of these at maximum height (usually around 40ft) and connect them to a Peplink HD4 to provide internet connectivity to the crew via 4 cellular modems (8 sims, active and failover). We have servers and other onboard systems as well as business email, people using Project use Dropbox etc and we use a combination of (slow) satellite and cellular to provide access. Cellular is faster and therefore preferred, but our boats are often more than 20 miles from shore. The array of these antennas picks up 2G and questionable 3G and upgrades it to 4G LTE (-90dB to -70s at 17 miles from shore and 40ft from water), which typically provides reasonable access for 30-40 people.
