Let's look at two popular RV internet options and see if one is better than the other and which one makes more sense for you.
A cell booster uses an external antenna to receive a cell signal. The booster amplifies that signal which is broadcasted by an internal antenna in the RV.
Come in both omnidirectional and directional styles.
Are great for locations that are farther from cell towers.
Great for giving you a strong cell signal for your phone.
Boosters are single channel antennas for both incoming and outgoing signals. Which means they can't receive data while it's being sent and vice verse.
So while they are great for low signal situations, they can actually slow down your connection in locations where you have a halfway decent signal.
MIMO, or multi-in multi-out antennas, use multiple channels to relay internet signal.
They don't boost the signal but get better reception do to their larger size.
The most significant advantage of a MIMO antenna is the increase in data speeds over a booster.
Some also come with WiFi and GPS antennas.
Some can be combined with hotspots that support multiple SIM cards for multiple carrier coverage.
They come in multiple price points from $50 to $400.
They require you already have a WiFi hotspot or purchase one with a kit. This can bring the cost up considerably.
They don't boost the signal. So if you frequently boondock in areas with only one bar of signal, a booster may work better.
...when you are frequently in locations with only one to two bars of service and need a stable connection?
...when you typically have three or more bars, but want a stable and faster connection? ...or when you use or want a dedicated hotspot modem?
