I'm not sure what to call it, but my antenna tower is just that common three-pole truss type structure, set in concrete at the base. Is there any reason I need some sort of J-mount, or if I can hit the aim I'm looking for, while doing so, can I just clamp it to one of the tower tubes? I know nearby metal can affect things, but with a bowtie such as this DB8e, don't the screens on the backside block anything from affecting it from the rear?
