When your radio station has the highest rate card in the nation and you decide to add an HD signal, the last thing you want to do is interrupt your analog signal. That was the situation facing KIIS-FM when they called on Jampro Antennas / RF Systems of Sacramento, California to space-combine their existing Jampro JSPC-1 Penetrator antenna. To ensure a seamless and successful configuration, Jampro resurrected designs of a discontinued model and custom built a new JSPC-2 to make the separate height antenna installation possible.
