Subject: [Premium-Rx] HF Antennas for the city?
After playing with a number of HF antennas I'm back to where I started, a discone. My lot is 30' x 100'. Traditional HF antennas don't work because the ambient environment is full of noise from power lines, neon signs, fluorescent lights, and wireless networks. The front end gets saturated with noise. Attenuators reduce the noise and the signal until I have performance equal to the discone. One BIG ISSUE, I cannot go more than 5' above the roof line due to local ordinances.
What I have tried that does not work:
100' Long Wire
45' Inverted V
20' Vertical Loaded
What I have tried that works:
WJ 34903 Quad Loop, 13"D x 18"T
Discone
I have not tried:
Horizontal Beam
Other unique small antennas
Mobile Antennas
Discone with HF element???
Both the WJ loop and a beam are directional so I can null the noise but may also lose the signal when off pattern.
What other choices have been tried in the city that work? I'm trying to avoid purchasing costly equipment that will not work.
Thanks,
Steve
