Tuned to Marine AIS: Each antenna is tuned to the VHF Marine Automatic Identification System (AIS) at 161-162 MHz. With the proper receive equipment, this allows you to track ships in your area. This antenna can also compliment a system setup for linking to an online virtual network, such as PinkFroot's ShipFinder.
DC Grounded: A metal ground plane is not needed with this design.
Enclosed Elements: The actual antenna elements and feed point are sealed inside a UV resistant plastic radome. No need to worry about corrosion on the elements with this design.
Weather Resistant: Having the elements and feed point sealed in the radome allows the antenna to be very resistant to weather and other environmental damage. This antenna is strong enough to withstand an ice storm, and will also do well in a shoreline environment.
Copper Elements: Elements are copper clad, which is a better element material than stainless steel.
Narrow Bandwidth: The bandwidth for the antenna is fairly narrow, which can help to eliminate intermod problems from adjacent strong signals in urban areas.
High Quality N Connector: Instead of the usual UHF connector that's included with most antennas, this antenna includes a 50 ohm female N connector, on the end of a small cable pigtail. N connectors are more water resistant and handle high frequencies better. Need help choosing your main cable? Checkout the Coax FAQ.
Includes Mounting Hardware: Price includes mounting clamps to allow attaching the antenna to any standard 1 1/4" to 1 1/2" mounting mast.

"I was pleased to see how well the AIS Marine vertical antenna worked for me. I have it at about 70' ASL and have recorded reception distances exceeding 200 nautical miles. This is with a 60' length of RG-8X, which I plan to upgrade soon to a better cable."
