See Product Review in November 2016 QST Page 59 62. Our new DDF2020T, you do not need to change the antenna to the receiver side even when the power is off. Now it has higher stability by fixing the problem of unstable connection of each base. In particular, the base of the antenna on the roof of the car is made with aluminum so that it does not become rusty. We hope you are satisfied with this product.

The appearance of product may be different from the picture. Case with assembled parts - requires a minimum assembly. The Antenna Module with magnetics on the bottoms. 3.5 mm Audio Cable Set. Receiver Frequency: Determined by user-provided FM. Receiver, range 100 to 1000 MHz. Antenna : Four elements, wave vertical with ground plane (recommended). Ant Scan : Scan rate 430 Hz, rotation clockwise (viewed from above antenna). Ant Switch : Modified Joe Moell Wideband Doppler DF antenna design. Employs Agilent HSMP3893 SMT PIN diodes. SMT / stripline circuit design, BNC output connector. Audio Input : FM receiver speaker audio, 1.0 K ohm. Output : RS232 Agrello DF message, 4800 baud, 8N2.

Ant Outputs : Four discrete active HIGH outputs for. DDF2020T Antenna (one per antenna) and 1 auxiliary antenna for improving it sesitivity and accuracy. Voice Filter: Switched-capacitor filter, (SCF) 4.

When you use RS232(Serial) To USB Convertor, please install the right driver comes with it. Antenna N should be placed in frontward of vehicle to indicate 0 degree of DF. When DDF2020 tunes with the right RF signal, it outputs clear 430 Hz audio signal which will indicates stable LED. Positioning and Map plotting program on Google earth.

The Navi2020 "map plotting" program accepts DDF2020 DF + GPS messages and plots them on a Google Earth display window. Manual latitude / longitude and DF bearing inputs allow operation without a DDF2020 DF. Up to 100 plot points allowed, and hunt results are saved in archive files. Google Earth normally works with an open internet link, but areas previously viewed are archived and available for offline viewing.

This makes Navi2020 suitable for use in real time mobile hunts, when an internet link is not available. DDF2020T Full Set (Antennas not included).
