I don't know about Ohio specifically, no experience there...
Not sure what your age is, and what your education background it, but what I can tell you from doing this stuff for 30 years:
-You need some solid data networking skills. So much of these systems are digital with IP backhaul. Companies will want your resume to show some knowledge/experience on that. Being able to set up a network link is important. You may already have those skills in your current job, just make sure you are presenting them correctly on the resume. 20 years ago you would get by without it and OJT would cover the rest. Not anymore.
-A lot of companies use the possession of a GROL ticket as a 'proof of knowledge'. Many will not even consider your resume if you don't have a GROL in hand. While GROL's are not usually required for doing this sort of work, it does show you have some basic knowledge. There are companies that will do a 2-3 day GROL course with testing for a few grand. You'll walk out with your GROL and a lighter wallet, but it'll get you noticed.
-Ham radio license won't do much for you in the industry. Might get you noticed by another ham, but the industry doesn't recognize a ham ticket as any proof of knowledge. Don't rely on that as your qualification. Hams will sometimes argue this, but (and no offense intended), passing a 35 question multiple choice test isn't proof of knowledge, and most radio shops won't care if you can work Albania on 20 meters, or know how to access the local 2 meter repeater.
-Some community college courses in basic IT might be a good start if you don't have those already. Basic electronics would be good.
-And then there's "all the other stuff". I can tell you that if 30 years ago someone had told me how much non-radio stuff I'd be doing, I probably wouldn't have believed them. I get pulled into all kinds of things where weird knowledge is required;
-HVAC - Cooling is important. You don't need to know how to fix the things, but I spend a lot of time dealing with HVAC issues.
-DC power systems. The radio system is only as good as it's power. Knowledge on DC plants is important.
-AC power systems. It's more than UPS's. Generators, AC power issues, etc.
-Knowledge on grounding/lightning protection.
-Basic automotive skills. If you are going to be doing mobile installs, being part mechanic is part of the job. You will be pulling stuff apart. In fact, a few of the guys at our county shop came direct from auto dealer shops.
-General repairs. I fix a lot of stuff at radio sites. I fix a lot of other people's work. I've cleared a lot of brush from around sites. I've dug my own trenches for conduit. I've driven my own ground rods. Anchoring equipment racks. I've fixed locks. I've fixed fences. High School shop class probably taught me a lot of that stuff.
-Being able to pass a background check. If you are trying to get into public safety related work, expect to be put through some level of back ground check. The level required will depend on what you have access to. Might be a simple wants/warrants check, might be fingerprinting, or might be a full background check, financial check, etc.
If I was starting in the industry right now, I'd take local college courses in networking, get my GROL and maybe some other certifications, like tower climber, etc. There can be some competition for these jobs, and the other guys may have all those things.
Also, as a newcomer to the industry, you'll get stuck with the dirty/tedious/boring work. Enjoy it, it builds you up. You may spend a lot of time wiring vehicles. Climbing up and getting to the point where you are trusted to program radios takes time. There's a lot of trust that needs to be built up there when officers lives are on the line.
