Hello Unit 211,
Welcome to the forum. First thing could you post a intro in the "Welcome to the Forum" topic,
viewforum.php?f=89 ,so others can say "Hi", thanks. Next grounding is always a great idea especially having a large lightning rod like a CB antenna on the roof. The ground wire only has to go from the antenna mast where it meets the top of the tower and at the bottom where the tower meets ground level to the ground rods. If lightning is to strike the tower the metal will take the strike to the ground. You may want to invest in a lightning arrestor for the coax and rotor control cable, these are installed outside, keeping the electrical charge out of the house. If you don't have a manual for the antenna you can download it off the internet, there are grounding instruction there to follow.
The front of the Y Quad is the end with the gamma matchers, that points toward the station you are contacting. The antenna is basically omni directional with a reflector to drive the signal forward but you will still hear station off the back, just not as stong.
I removed a second post similar to this one and moved this one to the right topic area, if you ever need any help just let us know.
