Yes you still might be able to pick up a stronger signal outside of the camper with a higher pole mount antennae, and thus extending that better signal into the camper and receiver. However, I've found that by placing my cell phone next to a window that is closest and directional to the nearest cell tower (or even dangling it outside of a window) and using it as a hotspot, generally provides the same level of service you'd get with a whole external antennae/internal receiver/wifi transmitter set up and associated costs.

No, I would disagree. The yagi antenna receives more signal than the tiny antenna in a cell phone can receive. That signal is amplified inside. I've gone from no reception (outside my trailer) to some reception inside, and no 4G (outside my trailer) to 4G inside. Granted, if there is absolutely no cell signal then there is nothing to amplify, but if there is a little bit of signal it can be amplified (boosted)
