Barrett Releases New ATUs

Designed Specifically to Operate with 4000 Series Transceivers

Barrett Communications (www.barrettcomms.com) has released new HF automatic tuning antennas (ATUs) – the 4045, 4049 and 411 – specifically designed to operate with its 4000 series transceivers.

Suitable for land-mobile, marine and base station installations, the 4045 can be optioned with anti-vibration mounting and is equipped with a built-in GPS. Suitable for ALE 2G and 3G operations, simplifying the installation of tracking networks, the 4045 typically tunes a frequency in less than 1.5s and tunes from memory – when paired with a Barrett 4000 series transceiver – in less than 100ms.

The 4049 Automatic Tuning Mobile HF Antenna has been designed to attach perfectly to a vehicle. The antenna comes standard with a two-section fibreglass whip, or can be paired with the Barrett NVIS Whip antenna, which can greatly improve communications in hilly or mountainous terrain. The integrated anti-vibration mounting system and integrated GPS come as standard for this model.

Built on an aluminium base rather than stainless steel, the 411 ATU enters the market at a lower price point. Although it lacks the in-built GPS capability of the 4045, the 411 is perfect for the professional, amateur or hobbyist markets, lending itself to bespoke installations with OEM transceivers.

All Barrett ATUs provide continuous coverage over 1.5-30MHz, subject to wire or whip antenna length, and full 150 W PEP (digital, voice and data) performance.
