All Suburbans are center fed half wave designs with decoupling techniques employed to assure maximum radiation at the horizon where it belongs. The SO-239 connector is protected from the weather. The slim fiberglass radome presents a tough bur aesthetically pleasing exterior that will stand up in any harsh environment.
