 Thanks for the feedback folks. Doc is on the right track. THe tuner 
 works really well (way to go SGC, nice product!) and the antenna length 
 doesn't seem to be impeding transmission distance. 
 
 Furthermore, the length, although not electrically correct for all 
 frequencies, is convenient physically for a sail boat. 
 
 Glad to hear that the 1000 mile distance I attained was acceptable 
 performance. My actual planned use is for keeping in touch with other 
 vessels (friends) that are within a couple of thousand miles tops. 
 Hopefully it will do the trick. 
 
 Thanks for the feedback folks. Muuch appreciated.

With a 50' antenna length and an adiquate RF Ground, one could 
consider that a respectable Marine Radio Installation. 
 
One thing that needs to be understood is that ALL Autotuners 
have a REALLY BIG difficency that is inherent in their design. 
They can NOT tune wires at the Half Wavelength point and 50Khz on each 
side.  At this point antenna impedance becomes Infinite and can't be 
tuned.  so a boater must make sure that he never intends to transmit 
on the frequency that is at the electrical Half Wavelength of the 
antenna.  He may need to lengthen ot shorten the wire to adjust 
for this condition.
