So as i understand when you use wifi boosters all they do is cut the signal in half to spread the wifi out further. 

Are you going to make sure the tenant goes back for every booster shot?

It seemed like such an anachronism, a relic of Southern California post-war hubris, or maybe even Gold Rush-style boosterism.

I think it is probably a great "confidence booster" once a relationship has been established as people do assume trust and integrity going along with law-enforcement.

Boosters are available if needed...

However, my cable TV went out recently and I could not get it fixed until I remembered that I installed a cable booster that needs to be plugged in and I went to the garage and saw the GFI outlet was tripped again and that seemed to cut power to the GFI outlet that had the booster plugged into it.So, now this annoyance needs to be fixed -- is there anything I can do myself to check why the GFI keeps getting tripped or do I need an electrician?

It’s your confidence booster, connection maker, and a load of experience.

The announcement, coupled with major expansions underway by Apple, Facebook, Tesla, and others, is a feather in the cap of local business boosters. 

Great confidence booster and helped me along the way to what I have now!

In some cases you can install a booster pump to increase water pressure, but there are obviously variables on whether this specific property qualifies for that remedy.
