Wi-fi antenna - omni vs. yagi
I'm looking at adding a booster/repeater system to our travel trailer, in the hopes of getting some better access to CG wifi. I understand that it probably won't be able to stream movies, etc. but I ...

an Omni is rated as "unity", as it has zero gain. When you start adding any numbers above 0db (unity) in DB, they represent gain.
Also, when rating antennas, one never factors in amplifiers. An amplifier cannot boost what it cannot hear. That's where the performance of the antenna comes in, which is why it's always better to have an antenna with gain in it if working on weak signals. You HAVE to get the signal above the noise floor to do anything with it, and that's not what receive amps do (at the antenna).
