The main thing you really need to learn is adaptability.
You need to develop diagnosis skills if you want to go into any form of maintenance and repair work, EE does not do that so much, neither does the installation Electrician.
Adaptability means you have the means to assess what you have, what you need and how to get there - you will need a mixture of skills and knowledge, and its hard to develop them all at once.
You might start out with an initial intention, but you soon find yourself following different pathways. This is absolutely essential, you need a wide range of experiences to try out - you tend to then fall into one direction or another.
Its rare for anyone to target one aspect of the electrical/electronic field and stick just to that thing.
I’ll second what casdave is saying. I am a Certified Engineering Technician in Avionics/Electronics (with a B.Sc in Geology/Physics) but in my present job work most of my labour is devoted with SCADA, solar charging systems, generators, and diesel engines. My job title is as a Senior Field Service Technician for a defence contractor as a radar technologist. Before that I worked on F-18s as an avionics technician.
Have you given any thought to joining the military in a technical role to develop your skill sets? I’m no recruiter but I learned a whole lot of skills well beyond my primary job, and they paid for most of my degree. Food for thought.
Not everyone gets the opportunity to choose for their orders. Besides, they give you your rate as soon as you get to “A” School. They’ll either give you Aviation Electrician or Aviation Technician.
Having the G.I. Bill is good but Tuition Assistance is a gamble when you work in a squadron. That’s what I’m trying to do right now.
The military helps you develop a work ethic and actually it’s given me more time to plan for my future (I was 18 when I joined). However, this isn’t everyone’s intention, people will just let time slip by and next thing you know, they have no idea what they want to do after the military, IMO.
I am an Aviation Ordnanceman working with F/A-18s and at this point of my career, I want to be confident in what I want to do in the next 5 years.
