need ideas and samples to install an 18" new garmin
on top of a 2 3/8 inches aluminum
tube about 8 feet long .
Checked on line the usual suspects Edson
etc.prices quite high.
Previously have just have a plate welded on top and then drilled the holes and bolted the base,however like to see how others have done it.
Also like the idea of pivoting the base to adjust the angle on long tacks that sort of level the dome.
Seems a waste to spend couple hundred on a adapter.
