The AX-81S antenna is a compact active HF antenna, ruggedized to suit harsh
outdoor environments, and particularly suitable for marine environments. While it
has been designed primarily as a marine antenna, it can be useful anywhere where
good HF performance and reliability are required, and where space is at premium.
The antenna is receive-only, and is suitable for professional as well as consumer
applications.
The antenna covers the frequency range of 2 to 30 MHz, or 300 kHz to 50 MHz
with somewhat reduced (but still excellent) performance.
The principal elements of the antenna are constructed of a low-carbon austenitic
stainless steel that contains molybdenum. Austenitic (chromium and nickel content)
stainless steels have high ductility (i.e. ability of a metal to plastically deform without
breaking or fracturing), low yield stress and high ultimate tensile strength, when compared to a typical carbon steel.
The 316L grade as used for the AX-81S antenna also offers an especially high degree of resistance to corrosion.
The choice of materials and the durable construction of the AX-81S antenna will ensure trouble-free operation
for many years.
The antenna was designed for rapid installation, with an easy-to-follow installation procedure supplied with
the antenna.

lations. Has an F connector. Make sure to choose the correct adaptor for your needs.

VHF/UHF WIDEBAND ANTENNAS
The WiNRADiO G33EM receiver supplies power for the AX-81S antenna at its antenna input, and no
external power supply is needed. For any other applications we recommend using a WiNRADiO SF-41
Low-noise Linear Power Supply together with the WiNRADiO WR-BT-650 Power Injector.
