"It seems most guys are using some sort of top loaded vertical. Are they 
using a radial system I wonder?If so how do you the radials ,antenna 
,horizontal tophat and feedline all within the 50 foot restriction?  The way 
Im reading the rule , the ground system and feedline are included in the 
total length .  Am I missing something or is everyone just fudging it?"

No, Rick, they're not all just fudging it.  Re-read the regs: "The total 
length of the transmission line, antenna, and ground lead (if used) shall 
not exceed 15 meters."  Ground lead...the connection from the transmitter to 
a ground, whatever form that may take.

The type of ground system is not regulated.  Anything from a single ground 
rod to your city's water system is a legitimate "ground" (not that those are 
all that effective at LF), and all you have to include is the transmitter's 
connection to it.

Of course, as Warren says, an experimental license gives you a lot more 
leeway.
