CB Radio not functioning - white noise only

CB Radio not functioning - white noise only
I’m trying to get a CB radio (~27MHz) up and running but I’m a bit of a novice. I believe I have the correct equipment, but on all 40 channels I only get white noise of varying strengths. I live in the middle of a city so I would expect to hear something. I will list my equipment below in hopes that that is the issue, other wise I am open to any troubleshooting steps people have in mind. Thanks in advance!
