As I recall, if the SWR dips (2 or 3:1?) around 7.8 MHz, then one of the DE traps (coils) is out of the circuit and the problem lies in the screw terminal on the coil (become open circuit). Definitel

Water in a connector can do that.  Looks fine on ohm meter but RF sees the very very high dielectric constant of water and shunts to ground.  This first got me when some water got into a Type N barre
