Re: [IRCA] Vertical antennas

[Alan Bosch <labosch@xxxxxxxxxxx>]

Patrick:

I am really curious about why you have that N/NE lobe if the radial 
pattern is symmetrical around the vert's base.

Part of the reason is that I plan to put some radials under my vertical, 
but can only get them in a semi-circle to the SW/NW, and I wonder if I 
might not do just as well with a tight circle of ground rods at the base 
of the antenna.

(BTW,  I have discovered the easy way to install in-ground radials with 
next to no sweat: use a little Mantis tiller with its single  edger 
blade.  Makes slits 3" deep as long as you want 'em.  And you can rent 
the Mantis cheaply.)

What makes you say it would be easier to add radials to the N/NE than to 
disconnect those in the other quadrants?
