There is an Italian translation of the “Mounting instructions” document of AAA-1 amplifier. It is available on this site. Many thanks to Ivano Giacchi , ZA / IK2RLM who has voluntary prepare the translation. Look at http://www.qrz.com/db/IK2RLM to access his … Continued
The new model AAA-1C is now available. There are changes to improve the mode and relay control circuit. Now the control circuit is optically insulated from the FTP cable control signals. This will improve the noise immunity and influence from … Continued
Hello all, These are the main changes in the new AAA-1C model: – the control circuits for mode and antenna relays are now with opto-couplers. This will increase the protection level of the device from external electromagnetic fileds. The power … Continued
I must inform you that all AAA-1B kits from the current batch were sold out. The next batch AAA-1C will be available at the end of October 2014. I am waiting to get them from the mounting factory. Check the … Continued
Hello all, Leif, SM5BSZ http://www.sm5bsz.com/ has put on YOUTUBE 4 videos named Sensors- Parts1 to 4. The addres of the first video (sensors – part1 ) is http://www.youtube.com/watch?v=ItLkn8r4s3E and the others can be find easily there. Leif annotation: “On low … Continued
Hello to everybody, The www.active-antenna.eu page has been reorganized with the following additions: Variable delay line kit VDL-1 is introduced to be used for receiving phased arrays (unidirectional) with small active loops and dipoles antennas. An article “ Additional Environment … Continued
Hello all, There are two new important articles published on LZ1AQ site www.lz1aq.signacor.com . The first article “Experimental Comparison of Small Wideband Magnetic Loops” experimentally analyze the effect of using crossed coplanar loops which might be important … Continued
The third batch of Active Antenna Amplifiers is now available . The model is basicly AAA-1B with some minor improvements in noise floor of the loop amplifier part (output noise power -115 dBm @ 10MHz). The specifications and documents are … Continued
Hello all, I must inform you that all AAA-1 kits from the second batch were sold. The third batch will be available within few days. I am wating to get them from the mounting factory. I want to thank all … Continued
I have put in Technical info section of this site a short file named “Wideband Small Receiving Loop Simplified” http://active-antenna.eu/tech-docs/wideband-small-receiving-loop-simplified.pdf . This is an answer to often asked questions about the wideband loop design. For more detailed study of this topic I … Continued
