low frequency (0-10MHz) antenna driver (voltage vs current source)

[CopperCone]

Is there any benefit to using a current source to drive an antenna?

Does anyone actually do it though? I was thinking of using a power-howland AC current source to drive it.

[voltz]

Without actually reading that PDF in detail and just from thinking first principles, i would think it makes very little or no difference.

Its all 'power' at the end of the day, either with more voltage than current or more current than voltage. But the result is always the same, power.
I suppose transmission lines are better driven at higher voltage than current to reduce resistance losses. But unless your feeders are very long and running at high power, i suggest there's no real difference. If anything, voltage driven would be better.

Maybe there is another reason why current fed would be better. Just can't think of one!
