Oke...what about a simple EFHW antenna roughly a half wave above ground...
Blue is without a mast....black is with a mast and its isolated from the antenna. I would say that is a difference .....

Or the t2tl this time black is without a mast...again...its isolated... the mast is 10cm away from the antenna ...ehm..4 inches and they "overlap" 4 inches (you need to attach the antenna to it)

And i didnt try to make things "worse case".... just a fast impression...I didnt verify the models...but im fairly confident it is of "influence" Could you agree DB ?
