KHV's exclusive RingFire™ Technology The new TracVision M-series antennas all use KVHs proprietary new RingFire technology, a remarkable breakthrough in antenna design. Fusing precisely shaped, tuned parabolic dish antennas with custom-designed, dual-mode feed tubes and uniquely modified LNBs, RingFire technology provides unmatched illumination of the reflector resulting in signal strengths that are comparable to competitors larger antennas. TracVision M-series antennas are up to 30% more powerful than KVHs TracVision HP products, which were already among the best in the industry. This means that with the TracVision M-series you'll enjoy wider geographic coverage and better reception, even in extreme weather.
