Topband: Vertical vs inverted L question/opinions

[Goldtr8 (KD8NNU)]

Thanks everyone for all the replies.

I guess that I will work on several things now for the next winter season.

First is the standby length of wire to use as an inverted L which I used as 
a fan vertical last winter.

Second I will also play with the coil loading on the 80m vertical and do 
some reverse beacon testing to see what happens with the belief that it will 
not be as good as the L

Third I will study my options with the trees to see if I can figure out an 
inverted T arraignment as this may be the best of all.   Now I have to study 
on how to calculate the length of such an antenna.

Also when the lawn mowing season is done I will add some more radial wires 
to the radial field.

Thanks for all the comments, now I have more options to play with and may I 
work you all on the air this year.

Don,

Others are far more knowledgable than I, but top loading has less loss than 
base loading so the L should perform better, all else being equal.

That said, I have been using a 60' base loaded vertical with 8 elevated 
radials and have 136 countries from a 1/4 acre city lot in the black hole of 
California,  I suspect the total would be a lot better with an L!

Good luck,

Bob
