WLBZ AM radio 620 KHZ. in Bangor, Maine  in the early 1960's had a reduction in 
the ground wave signal 
most noticeable over 40 miles.  We  found the radial connections installed in 
the 1920's were in tough shape. 
 
Ran new radials and inter-connected with silver solder. After the work was 
completed 
could copy the station ~130 miles distant in Portland Maine on a car radio.

PS remember how long those old car radio antennas were? hi

      I had soldering problems here in the salt air until I switched to

are in great shape, exposed to the elements. 
YMMV
