SIRIO Gain-Master!

December 2022 I invested in a new antenna for 10 / 12m.  the Sirio Gain-master to either replace or run alongside my 25 year old Imax 2000, The Imax has served me well for many years and is still standing erect, despite spending 15 years on top of my roof on a 40-foot pole bringing the base of the antenna approximately 75 feet above the ground.

The antenna has survived high winds, snow, Ice, etc, and still keeps on ticking.  I decided to try out the Gain-Master antenna as there were many good reviews about it online, I needed a second 10 to 12 metre antenna anyway, well that's what I convinced myself.  Here are details about the antenna.
