Beth,
It all depends on the motivation and willingness to learn of the
individual. As long as you have a desire to pursue a new career, you are
only limited by yourself. Given the proper training (usually as an
apprentice) there is no reason why you could not be an electrician, or
in more specialized terms, a communications wiring specialist. However,
keep in mind that there are many ways to do more harm, (including
creating potentially fatal configurations), than good when working with
electrical wiring and lightning suppression. Get some training, be
careful, and go for it.
