Hi,
I am fixing my 40m wire beam. It is a 2 shortened elements added to my HD
spiderbeam.
About 3 months ago my 40m driven element was hitted (or almost) by a lightning.
The result:
The wire of one arm was cutted on both sides of the loading coil...The coil is
in the middle of the arm.
Few days ago helped by an Skyhook (Crane) I installed the loading coil again.
Checking the SWR with my MFJ-259 I see the SWR is 3:1 or more on any HF
frequency...Probably the Coax cable is broken in some place...I check the coax
from the shack to the top of the tower. I can see on top of the tower the coax
without about 1 inch of the external black jacket (It is RG223 coax
cable)...The braid is not broken but it is black in that place (like cables
after a shortcircuit)...or arching because the HV...
My question is:
Is the center conductor of the coax broken in that place???
any idea?
Thanks,
Doug, CO8DM
