Wifi - cable connection via Antanna (how?)

ok here is my idea of doing this

[ANT]---------- Catv----------- [Cable Modem]-------- Cat5 --------[Router/Switch] ----- Cat5 ----- [network]

so basically this is creating a "Receiver" for a wifi connection than converted to a cable connection than transmitted via cat5e to a router, switch, and/or a transceiver than divided into a network of computers.... now i have a couple questions...

i believe "WiFi" is Radiation of some sort that carries electrical current... the antennas are directors of which way the current is aimed at it like playing passing football. you hold you arm up to "Catch" the ball which the ball is "Electricity" that is than manipulated by metals. (wait a sec..... ok here is my idea that suddenly came in to my head. back in the day they used morse code to transmitte electrical "spraks" that hit a bell or metal plate... so like this:

[+point]<Collide>[-point] ----- creates electric spark ------> travels in a copper highway ------> finds a [bell] than make beep sound

this is like throwing a rock at your neighbors mail box .... Gravity is the neg and the forces of movement of my arm is the pos they both collide and create a pressured release and which the rock travel though the atmosphere and than finds it way to the mail box and makes this loud band sound... OK so you us the antenna to catch the "Electro-Radiation Current" and transmitted tho cable "Isolated Copper" (fiber optics is isolated pipelines that are a super highway for light.) than that cable is than transmitted and converted via modem to than create a task management system for how the "voltage" is distributed than is now amplified to give out deliverance to a compatiable device which is a "computer"

AM i wrong or am i rite...?
