	The HF2V also requires RADIALS, as does the MFJ-1792.
	A set of light weight non-conductive guys could easily be
	placed within the space devoted to radial placement.
	Even steep guys are better than NO guys.

	I would NOT recommend using a 1/4 WL (electrical) 
	vertical without radials.  Even short radials are better
	than NO radials, just as a short antenna is better than
	NO antenna.   (Enough of this ! )   N4KG

	Agree. I will even concede that it is easier to retune
	the HF2V since the coil is accessable from the ground.

	The MFJ-1792 has a nifty tilt base to facilitate raising
	and lowering.  It would be interesting to see how they
	both work on SSB with a tuner if tuned for CW.  That's
	what I do with my full size coax fed antennas.  N4KG

	Thank you for having an open mind and looking at the facts.
	I have no idea why MFJ doesn't do a better job of promoting
	this interesting antenna.  I have suggested they advertise it
	in the NCJ and DX magazines which have low advertising
	rates due to smaller circulations yet target the most 
	likely buyers of  80 / 40 verticals.   N4KG

	No one likes to have their antenna called a "DOG",
	especially if it has done good things for them.
	I didn't like the "modified G5RV" characterization as 
	a DOG in a separate thread and responded similarly.

	That is a good point.  I do stand by my contention that
	the MFJ 1792 has the potential to be a *better* compromise
	on 80M than the base loaded HF2V *without* top loading wires.
	A top loaded HF2V is probably a better radiator as well.
	Note that the top loading wires need external supports
	and possible additional guying.  

	I hope we can put this thread to bed now, at least until 
	further performance data or experience is available.
