As a person that
hires tower service companies, I seriously would not recommend it as an entry level employee... The pay is horrible, the benefits suck, you'll be travelling 75%+ of the time. The bar to entry is very low if you're physically fit. If you don't have any DUIs and can pass a drug screen you are already ahead of many candidates. Most of the recruiting takes placein social media these days, for instance there's probably 20 or so tower climber related groups on Facebook.
One of the reasons for the extensive use of social media is that to put it as politely as possible, the talent pool they're recruiting from are not highly educated, often don't own laptops or any device other than their phone. Many cannot put together a grammatically correct cover letter or CV. There is a very high turn over rate in people with less than 2 years experience. You will be working with (and sharing the cheapest possible motel rooms with) some very crude and uneducated individuals, with whom you might have nothing in common. All that for a rate of pay about the same as Dicks Burgers pays in Seattle to literally flip a burger, and Dicks has much better benefits.
The majority of the work will be mundane cellular tower and monopole stuff, unless you are hired by one of the more rare and specialized broadcast industry tower companies. The tower erection specialists are also a whole different ball game from the cellular industry contractors and subs.
The industry in general is a frustrating race to the bottom in subcontractors, turf vendors, subs of subs, unpaid invoices, and similar. It's very much like getting into any other hard labor construction job like roofing.
For the person in the thread here that said drones can only fly to 400 ft, not quite, the faa has specifically addressed this.
