Back story first... I followed the "White Paper" from Palomar to build a full spectrum long wire (not random length) antenna. From the top of a 45 foot Pine tree, the wire angles down, 99' to a tree in front of the shack and then drops another 30 plus or minus feet vertical to the 9:1 Palomar 'Cube' mounted 18" off the ground as stated in the documentation. 135' of coax is required, I had 150' and so it was. I am more than happy with this antenna! I have had my call sign for about 8 years and have done my fair share of 'fiddle and faddle', trying new things, today marked a new experience. I moved an HF rig to the garage, as I spend most of my day there, as I care for my 92 year-young mother over the past 4 years, I attached 50' of coax to the antenna and brought it into the garage and as I connected the coax, sparks flew! The barrel of the connector showed signs of Spot Welding and burn marks! I have radials of random lengths, above ground and on the surface. There is an Edison power pole in the corner of the lot with steel cables anchored underground, so I grounded the counterpoise to this steel cable. At one point, I took a shock when I had the coax in hand and went to connect it. I seriously thought I just killed the radio! I know about RF Burn, but this is entirely knew... Anyone 'Been there Done That'? This is so not good. Everything still works, I just don't care to have that happen again. Perhaps a real ground rod?
