Just want to point out the Gain-Master does not like another horizontal antenna directly underneath it. Being a balanced design, its TOA is pushed above the horizon more than an end fed groundplane would be in this type of installation. Just adding a large TV antenna 6 feet under mine, shaved off some performance that I could measure. Very little change in VSWR but I suspect if I was checking the bandwidth ends, they would have also shifted.
