Once, I had a forty foot tower topped with an eight element Yagi, a tripod mounted on the roof with a four element Yagi and, a random length wire connected to my Dentron Super Tuner Plus, that was "yesterday". Today, I am in a third floor apartment, been here since 1995. For 16 straight years, the Maintenance Manager would terminate "With Extreme Prejudice" any attempt to attach or extend a wire out of my apartment to use as an antenna. Finally, that fellow got promoted to the home office in Dallas and a new crew took over.
With the new crew came the opportunity for me to string an antenna, the new manager even allowed me access to the roof! Hastily, I threw together a OCF Dipole of random length #15 coated magnet wire. The antenna is fed with 75 ohm flat double lead, one leg is orientated horizontally in an East-West direction while the other leg comes off the dog-bone insulator vertically for six feet then goes horizontal on the roof; both ends are supported by insulated bog-bones. Picture an "L" that is thirty-five feet above ground (one leg higher than the other). All equipment chassis have an individual ground connection wired commonly to the metal frame of the sliding window; outside, there is a piece of #15 wire connected to frame of the window that drops three stories to a grounding rod.
My Station (and the rest of the household electronics) is situated on the same plane as my East-West leg and my radio is directly under my North-South leg. With the Dentron, I can tune 75, 40, 20, and, 10 meters. Everything is cool until I use 10 meters, it knocks the USB out on the laptop and freezes the dual core desktop computer; this is at QRP levels on PSK-31. I run power on 40 meters with no problems.
I guess I should say the Shack is in the RF Field.
