What is it? Aziloop DF-72 is a dual-mode
multi-directional antenna system for VLF to HF reception with features unequalled at this price point (or possibly
anywhere): ·
Uses low visual impact, small
footprint antenna comprising a pair of orthogonal loops plus an earth. ·
Stepped-Azimuth
technology for electronic rotation. The actual antenna remains
stationary. ·
Control everything from an intuitive Windows UI with selectable Local,
Client or Server mode. ·
Dual antenna modes. Switch between Loop mode and K9AY mode with mouse wheel
or buttons. ·
108 antennas in one: 72 K9AY headings
and 36 loop axes. Change with
mouse in 60 ms. ·
Switchable 18 dB preamp and a 4-step attenuator (0 - 18 dB) for up to 36 dB of level control. ·
Four 7-pole preselection
filters to give your receiver an easy time. ·
Variable K9AY load. 250 Ω to
950 Ω in 50 Ω steps ·
Two control/monitor ports for your own
use or allocate one or both to PTT muting. ·
Headless Remote control (no attached PC)
via the controller’s built-in Ethernet Server. ·
Omni-Rig support for auto-filter,
PTT muting and Rig-Sync (keep Rig A and Rig B in step) |

Over to you:
|
Add a clean 13.8 V power supply, a Windows PC, and your own build of
antenna, sized to give optimum performance for your use case and location. The antenna dimensions below are a good starting point for an urban
site. Optimum size depends on target frequency range, site noise, and system
noise (Single loop illustrated. A second identical one at 90 degrees
completes the installation. The LCU can be mounted inside or outside the loop
area.) |

Who should consider Aziloop? Aziloop will be of interest to shortwave
listeners, radio amateurs, and professional users alike. Applications include
general monitoring, co-channel station resolution, basic direction finding,
atmospheric and electromagnetic interference reduction, and jamming
mitigation. Plus of course just having fun learning about propagation and
discovering what your previous antenna was keeping from you. Product Positioning Aziloop has capabilities that single loop
antennas cannot offer. Occupying a different market sector, Aziloop is an
intelligent first choice, or a rewarding upgrade for the discerning listener. Professional Users Aziloop offers a feature-set that could meet
your project requirements at a fraction of the expected cost, especially for
tactical / SIGINT deployments. Custom builds may also be possible. Please
contact us to discuss your needs. |
