[Lowfer] antenna current

1/4th acre huh??? Piece of cake then. You can easily get down 135'radials
and some longer than that. Cut them in 135 and 66-foot lengths so at some
point in time you can run the vertical on LF, 160 & 75 meters. Run them all
over the place and take some and terminate to different lengths of copper
water pipe. Solder the wire to the pipe and bury it so it isn't sticking up
out of the grass. That will make a nice LF ground plane and work well on the
two lower amateur bands.

OK, I've replaced my dmm with an analog panel microammeter with NO leads
-- the components that comprise the rest of the RF current meter are
connected directly to the screw posts on the back of the panel meter.

Now when I connect radials (only 2 so far) the antenna current doesn't
(appear to) drop.  My longest (of the 2) radials is only about 50' but
I'll be adding more today.  I only have 1/4 acre though so I'm limited as
to how long I can make them.

Thanks for the help,
Eric
