Does it matter that the outer sleeve and radiator element are connected

Hi David,

ALL connections contribute to radiation. Their combination is what
builds the familiar lobe characteristic.

The actual antenna only connects the sleeves to earth braid and the
centre conductor does not touch anything ?

That's one way, the convention - could be t'other way 'round too; and
perhaps more interesting.
