The AX-81S Active HF Antenna is a compact active HF antenna, ruggedized to suit harsh outdoor environments, and particularly suitable for marine applications. 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 AX-81S Active HF Antenna is an excellent match for WiNRADiO WR-G303i, WR-G303e, WR-G313i and WR-G313e, shortwave receivers, and WR-G33EM marine receiver.

• Type: Active HF antenna monopole
• Frequency Range: 2 – 30 MHz @ 3 dB (excellent performance from 300 kHz to 50 MHz)
