"Please note that if you are going to use your Sirio Gain Master for DX purposes then it should be as mounted as close to the ground as possible for optimum results. On the other hand, if you are only use the antenna for ground wave purposes, i.e. talking to your mate 5, 10, 20 miles away then it must be mounted as high as possible and away from obstructions" I borrowed this from this gentlemans web site Sirio Gain-Master Hi-Tech Fibreglass Base Station Antenna for CB & 10m Band - Tetraplegicliving.com and was wondering if anyone had tried the gm at ground level? If so what kind of swr were you getting and how were your dx results? If no one has tried it perhaps a discussion could be had on the theory behind it. Thanks in advance.
