Sirio is claiming the Gain-Master will have at least 1db more apparent gain then those types of 5/8 waves. Not because the field is stronger but because the center feed lowers the take off angle. I would love to report that I will have the time to spend testing the Gain-Master against several antennas at a wavelength above ground. The reality is I'm juggling several projects as it is to complete them before winter and can only spend perhaps an afternoon field testing the antenna at only 15 to 20 feet.


I do have several antennas in stock that I can assemble to test against. I have a few old model Vector 4000's, a S-827 5/8 wave and a S-2016 5/8 wave. The S-827 is buried in a box behind lots of stuff but the other two are easy for me to put together. When the Gain-Master arrives next month, I'll test it against a Vector and the S-2016. One thing I'll add is that Sirio has taken the time to thoroughly test their antennas and they report some of the most accurate results you'll see in this market. The construction quality of the Gain-Master also seems to have been a focal point in it's design.
