APT Antennas Woodhouse cut-frequency APT antennas offer unmatched performance providing a higher quality image on your screen. Cut for 137 MHz.
Balanced design provides improved gain and pattern response far superior to unbalanced systems.
Tuned coaxial balun matching transformers offer peak performance on APT satellite frequencies, while rejecting out-of band signals. True circular polarization on all models for maximum NOAA satellite signal strength. Extremely heavy duty construction for long life and dependability. All components attached with machine screws which penetrate the entire threaded mating surface. No sleazy sheet metal screws.
