The antenna is too efficient now; my "Flying Vee" Dipole (40 feet in elevation, with one leg running up 10 feet directly up the wall and over the operating position to the roof; that leg is about 30 feet in length. The other leg is about 35 feet in length, it is running parallel to and at the same height as the all wiring and CAT-5 in my apartment!) radiates now in such a way that, the RF gets into my computer that I use to run the sound card modes, eQSL and LoTW logs.Originally Posted by kb2vxa
Before, I only had this issue on 10 meters (coming thru the USB bus on the computer), the feed to the antenna was sloppy (75 ohm flat line TV antenna wire) and, one leg was, #16 gauge stranded wire with the mica block for an insulator. Now, it's feed is balanced properly with #12 spaced by dog-bones.
All antenna wire is now, #15 formvar coated magnet wire.
Nope, I cannot change the orientation of the legs, all equipment is grounded to the same point which (my third radiator) runs down three stories to a ground rod.
