So here is my issue: I currently live in my RV on a temporary assignment 850 miles from home, anyway, the park i am in provides a wifi that is a 2.4 GHZ, with a strong signal, but it is very slow; speed test on my desktop shows it is about 4 - 5 MbPS. It is horrible for my firestick tv. Now there is a 5 GHZ xifinity wifi, that is much faster; speed test shows it at about 90 MbPS. My alienware Aurora desktop will connect to it just fine but the signal is not strong enough for my firestick. I currently have a 25' antenna mast with a coax celluar booster on it. I want to get an antenna to mount to the mast, run the cable into the RV and hook it to a router/repeater so that both our desktops, and firesticks can connect to it. Preferably i would like a setup that would booster both 2.4 and 5 GHZ, but for certain want to do that with the 5 GHZ system. There are many systems specifically for RV's that will do this, but they are all for 2.4 GHZ signals. I am not a techie so putting one together from scratch has so far proved daunting and every sales place i talk to wants me to buy their equipment for around $1000 (a 2.4 camp pro is $150). The big issue from as far i can figure is that the cable needs to be about 65 feet total length. Can somebody give me suggestions on what i need? I will be at this location for another 3 1/2 years and cannot deal with the parks slow internet any longer. The wifi route is the only choice, private cable is not available in the campground and the only satelite service here is outrageously priced. Thank you.
