Abstract
The invention as disclosed is a buoyant cable antenna configured for both VLF/LF and HF signals. A 100 foot antenna element has a low-pass filter assembly positioned at the midpoint of the antenna element to block HF signals. The outboard tip of the antenna element is shorted. In this way, the antenna element appears as a 50 foot open circuit antenna element to HF signals and as a 100 foot shorted antenna element to VLF/LF signals.
