Questions on broadband antenna design (e.g. T2FD)
An LP near ground also functions as a NVIS antenna, a broadband NVIS antenna.
You will need more space than the B&W for example; but, if space is available a
six or seven element design should work just fine.
Also, any TERMINATED TRAVELING WAVE designs should work. A 1/2 wavelength at 3
MHz terminated in 600 ohms and fed with a good 9:1 balun would do as well.

BTW: it is proximity to ground and horizontal polarization that causes NVIS

A wire based Log Periodic?
Good evening, Dave.
I guess I forgot to mention ... this antenna needs to be omnidirectional
or nearly so. Anyway it needs to be NVIS and I suspect a log periodic
wouldn't work well in that configuration.
