ADS-B Antenna 1090 MHz


Before buying a commercial ADS-B antenna, look for information on the Internet about antennas for this band, luckily I found several DIY designs with which you can test and see how you receive the radio signal at 1090 Ghz

The most successful design was the construction of a Quick Spider antenna posted by abcd567 on the flightradar24 forum.

My test build is a little different, I made it with remnants of radio material that I had at home and the truth is that it works, It is mounted on a pole and only has the NE angle which is limited.

After seeing the results, I am considering not buying the commercial antenna and mounting the Quick Spider with N connectors+low-loss cable+IPS watertight box and anchoring it to the radio tower, dhere it will be mounted with a 360ยบ view of the horizon.

SDRplay ADS-B

Today I have tested the ads-b plugin with the SDRplay RSPdx, Tech Minds guide is perfect and explains it step by step. In less than 15 minutes you will be receiving the aircraft data on your receiver.

You just have to have the latest version of the sdruno software, follow the instructions in the video.

My result in number of aircraft was not very successful because the reception antenna is not adequate, but soon I will solve this problem.

Icom SHF Project

"Icom Incorporated (Headquarters: Hirano-ku, Osaka, President: Hiroshi Nakaoka) has been doing technical research on a new project to create a product from scratch by utilizing our wireless communication technology knowhow cultivated over more than half a century.

Under the theme of "ICOM SHF Project—Super High Frequency Band Challenge —", we started to develop a new amateur radio available for use in the 2.4 GHz and 5.6 GHz bands.

Icom engineers are working hard to research and develop a number of never cleared challenges within the SHF band, such as large cable loss and higher frequency stability requirements. The ultimate goal is to bring it to the market as a new radio product."
