Hi Denny,

Dropping a full 1/4 wave wire from the neighbors tower would be the
simplest....cheap....approach.  I have no interest in building or buying
mobile antennas since this is only a one time test...not a investment. 
Gotta save the $$ for the fishing trips.

I can only do that distance to the neighbor. The radials will be added
symetrically over 360 degrees but I have only one point of measurement.
Once I get a handle on this I can then get other fixed station hams in
the area to help and have more azimuth points.

Why?  Just let it run until Im thru. There wont be very many ...if
any...people on 160  during daylight hours and 10mw wont go vy far.  At
1.5 wave away I do not need much power and can attenuate the 2N2222
output as needed.   

Im wide open to any suggestions...within reason!
