I'll chime in because I basically did what you want to do. BA in Film, but always had a passion for aerospace. First, what I did:
I had been taking flying lessons but also craved to know more, so I enrolled in A&P school, then worked as an aircraft mechanic for a short while. Saw technician opening for a comm sat manufacturer, applied and was hired into assembly and test. Most of my co-workers were also A&Ps, which they liked due to the wide variety of skills we possessed. Of course, it was all OJT from that point, but I worked my way up to lead tech aka engineering assistant, in charge of my own satellite and a couple of technicians. Amazing time, our group traveled for testing and went to launch bases for the Proton, Ariane 5, Sea Launch, and now they've have a couple of Falcon 9 launches. We knew satellites inside and out, from the waveguide screws to the solar array motor installation procedures. Our group put the satellite on the rocket, and were the last ones to see it, ever. Thousands had a hand in designing and building it, yet our merry team of 10 or so put her on the rocket and send it on its way.
Ok so to respond to your question:
For a technician job, you don't need a 4 year degree. You will only need a trade, like A&P for mechanical tech position, and an electronics/electrical certification for electrical/RF tech position. You have to decide if you want to do mechanical or electrical. As far as satellites go, they are heavy RF/electrical, so that would probably be the way to go, although I loved mechanical. There can be some crossover when you are on the inside, but you have to have skills in both.
Be sure the program you go to will get you ready to take the A&P or avionics test. For avionics there is a new certification called AET(http://www.aircraftmechanic.org/showthread.php?1983-NCATT-AET-certification
). TRY LOCAL JUNIOR COLLEGES FIRST BEFORE CONSIDERING EMBRY RIDDLE OR OTHER FOR PROFIT TRADE SCHOOLS. JCs are cheap and you get the same licensing. I knew people that had 40k in debt from A&P school which is insane for a 2 year trade program.
If you prefer electrical/electronics, just do a regular electronics program instead of an avionics specific program, because you will build circuits and devices from scratch with breadboards and the individual components. Also, go all the way to RF/antenna advanced courses which should be the progression at good junior/community college programs anyway.
Just be aware, this is an engineer heavy industry, and there is a glass ceiling for non-engineers. However, techs are hourly and get OT, while engineers are on a fixed salary. Even if they work a lot of OT, they don't get the same OT pay as techs, so you can earn more than then in any given year. You can make a career out of it though and move into management. Your degree does count a little, in the sense that most techs are not college educated so if you are good technically, you'd be a management candidate.
Also, engineers are not hands-on, at least where I was. So they could only stand around and bark orders. The thing is, the techs are so in tune with the spacecraft, that the engineers needed us just as much as we needed them. They would come down from their office when we had a problem, and we'd "suggest" a fix. The arrogant ones always got upset, but the cool ones got it, and respected what we did. For the most part, the engineers looked down upon a mere technician, and at times for good reason. There are some idiot techs out there that shouldn't be in the biz. Don't be that guy!
Finally, you can always try applying right now. There were some techs that somehow got in without A&Ps or trade certs. I'm on the business end of things now, dealing with aircraft, spacecraft, launch vehicles, UAS, all of that, but my technician positions got me here. I am not an engineer, just a guy with passion for aerospace and the willingness to do whatever it took. Hours at the bottom of a vacuum chamber wiring test equipment, riding with the spacecraft on the train in Kazakhstan in the middle of the night, hanging upside down to install coax cable under waveguide. I loved it!
So good luck to you, and let me know if you have any more questions.
