If you want to offer an objective reason WHY one thing is 'perfectly correct' - no worries. We can discuss. but I see no hard facts in your reasoning.
If you want a techy discussion, fire away..

RF is not a finite subject, theory and practice no not tally in the real world. IF you say a lower insulator is needed - WHY >>> ?
or strip foil ? WHY ?? how is it better than wire in the real world..?

WHY is a dynaplate 'good' - I can tell you it ISNT.. not needed..
WHAT are you trying to achieve with a 'groundplane' system that a single wire counterpoise on the apx freq of use cannot offer ?.. WHY do hams use multiple counterpoise wires in some vertical installations ?.

Why spend money on things you dont need.
Most boats have a through hull as a start - and often ALL they need for groundplane.. WHY NOT use 5p capacitors to link an rf ground using heavy items ?

People are too quick to post WHAT THEY HAVE READ - not, what the have understood and experimented with in an objective way..

Mind you, you wont reply, ignore user is a great thing.
