You get plenty of choices with the omnidirectional SeaWatch 2025 Marine TV antenna system from Shakespeare. Its innovative design lets you adjust its amplification for best picture quality. Increase the Gain to a full +20dB where the stations are weak, or attenuate -10dB where the signals are strong. A convenient knob on the included control panel makes adjustments to the antenna easy. The control panel can be mounted in wide variety of ways - flush mount it, surface mount it, or attach it to your TV set. The antenna head is mounted by simply clamping it to any 1" diameter pipe, extension mast, or straight mount. The 2025 also provides an auxiliary input for cable or satellite connections. When the 2025 is turned off, the auxiliary input is automatically connected to the TV, eliminating the external "A/B" switches required by other systems. Two-year warranty.
