This antenna is specially designed by Vesper Marine to be used with the Vesper Antenna Splitter. Up until now you've had to choose an AIS-tuned antenna that is optimized for the AIS frequencies but has lower performance for your VHF radio. Or you could choose an antenna that is designed for VHF radio communications but isn't optimal for AIS. Either of those works but Vesper has a better solution.
Vesper has created an antenna that solves this dilemma. It has two key features that combine to make it ideal for use with our antenna splitter:
The result is an antenna with superior performance over other designs. It has less than 1.5:1 VSWR at 156 MHz all the way up to 162 MHz. With other VHF or AIS antennas you'll only get low VSWR at one end of the frequency band but not both.
Vesper has put all of this into the same physical package as our most popular antenna. It's perfect for installations where the lowest possible windage is a requirement. A detachable cable makes installation and maintenance easier and allows for any length cable to be used. It easily mounts on a mast but is also suitable for mounting most anywhere with it's included L-bracket. Examples of mounting locations from our customers are; along side solar panels, bimini sides, on an arch, above a radar, or along the edge of a cabin top. The L-bracket can be removed allowing for even greater flexibility in mounting.
