When it comes to effective communication systems, it often pays to invest in your equipment early on in order to avoid unexpected costs later down the line. It is advantageous to invest in professional grade radio equipment for many reasons.
The first and most obvious is the quality of the hand portable. Better clarity, tougher equipment, and higher wattage. This equates to a much more reliable radio system which you can depend on.
Another significant advantage is that in the long term, although the initial investment is higher, it is often much more cost effective to invest in professional grade equipment. This is due to spare parts being available to professional radios. Amatur equipment doesn’t have spare parts available meaning when the radio breaks; it really is broken.
