Better Wi Fi capture in campgrounds

I, too, am a JefaTech user. At most parks, I've found that the repeater's own dual antennas are much better at picking up a signal from the campground. Quite often, what users assume is a lousy campground signal, is, in fact, more closely related to a poor onboard wifi antenna in the computer. Those things work great in a home wifi arena where the broadcaster is in the next room, but, less so, when the broadcast source is even upstairs or in the basement. Getting a better antenna will usually fix the problem; JefaTech's repeater has dual vertical antenna elements that can do a better a job of picking up a poor signal. Most of the time, they work fine for me, but, occasionally, I have to resort to their roof mount antenna to get the antenna above the clutter. Never had that fail me yet. Once the repeater is set up to the campground's wifi system, then it broadcast's its own wifi signal within my 5er so that all of my equipment can use it at one time. What others have said about the bandwidth is true...no amplifier or other system can add bandwidth; it is either there or it isn't and if it is all being used up by some clown streaming Netflix, then you, me and the rest of the campground is usually up the creek.
