WiFi signal booster ?

[Poohbear]

All I want to do is strengthen a WiFi signal when Im using my RV set up in a RV park when traveling and they provide a wifi signal but is weak. I don't really need/want my own internet such as Starlink Mobil etc. Suggestions please. I need this for the few occasions my Son meets up with me when we go fishing and he sometimes needs a secure signal that isn't cell based if he has to do a little lawyer work
On my RV I have a Winegard 360+ that I can add a booster & internet BUT the add on module is close to $400 . The pro is it can provide an internet subscription (cell based ) if I later want that. Im happy as punch when traveling to only have OA TV as my Verizon cell plan has unlimited data but my Son cannot use my hot spot

Are you wanting to boost your own WIFI originated signal or boost incoming WIFI signals from other providers?

You may need a booster with a directional antenna.

Or any directional antenna (such as a Yagi) with a WiFi card and the appropriate connector.

A lot depends on how technical you are. With either solution, you'll need to be able to sweep the antenna while watching signal strength, so you can find the correct direction for the antenna.
