Thanks for all six of the responses I have received so far. The Kenwood 
850 has an internal antenna tuner. It worked fine last year  at Handihams 
radio camp in Malibu.  That was with a G5RV. The R7 is just like it was 
when I acquired it from the estate of silent key Bob Larson, except for 
one joint half way up the mast and the 10 radials at the base. Would 
polishing up the surface do any good or does rf not care? I couldn't use 
it San Francisco because my lot was only 22 feet wide, but now I have 75 
by 300 feet. First I'll try the suggestion from two of youto put the twin 
lead straight and perpendicular to the long line, but at an angle to the 
ground. I's new and connects directly to the transmitter. I've used two 
different coax cables on the R7 with identical results. The ground is 
fine. I could get the G5RV higher if I could figure out what to use as a 
non-metallic mast. Any ideas?  Would it be worth buying an external 
antenna tuner to use instead of the internal a t in the K850?
Again, thanks for all the quick help. I don't stay on this list because 
there is too much traffic for me to add to what else is coming through, 
but it is great to get back on now and then. I'm always available at
