Would be interesting to see if you can find a unit to try first - either borrow or get a money back agreement. Most boosters will up your signal 1 to 2 bars at most, and if you are only at one bar that may not be enough for "work from home" quality internet, especially if you are doing zoom meetings.
I was able to try ours out before we bought it, sort of.
We were at an RV rally in Goshen, IN, and there was a vendor there from TechnoRV who was selling the boosters (as well as several other items). While discussing with him about wanting to try it out, he invited me to go to his RV and try it out myself using their unit. Being able to see the difference it made (the rally was thankfully in a bit of a dead zone, so it actually did make a difference) I was convinced and bought one. Whether or not it's going to work specifically for work, is hard to say. I've rarely done any work in the RV, except under extenuating circumstances, as our camping trips are vacation time. I don't even bring the work laptop unless I have to, and I've got my phone setup where I have to use the web browser to open outlook's web access to see my work mail, and no direct pushes to my phone. This has really helped me to stay disconnected when away.
There are others out there that 'full time' from their RVs, and these kind of boosters are all they use. Those people tend to run multiple devices, like having a Mifi and a JetPack with different providers, so they can use the one with the best signal, and they will typically separate their internet from their phone usage. Not sure if this is capable on Zoom, but I know with WebEx this is possible. Connect to the meeting with one device, and instead of running audio over the same device, you have WebEx call you and you do the audio over the other device. This will free up some congestion.
I'm not one of them, so for those rare occasions where I do have to work, I will make sure all background processes, updaters, backup utilities, etc... have been shut off before connecting to my phone's hotspot, and with that minimal amount of bandwidth used, I can usually make it through a meeting without an issue. Mind you, there was one case where the campground we were at was far enough away that the phone actually had like, no signal. The phone dropped into voice only 2G access. Without an LTE signal to boost, even my booster didn't help and I had to throw the laptop in the truck and run into town to the local McDonalds to get the work done that needed getting done.
