In the world of amateur radio, establishing your own setup and making your first contact can be a rewarding experience. This was evident in the recent project undertaken by Adam Laczkó, OM2ADM, an 18-year-old HAM enthusiast from Slovakia. Adam decided to build a QO-100 station as part of his final school project, and here’s a…
Drone as Satellite: Custom S-Band IceConeFeed for ESA Indoor Navigation Research
ESA-funded indoor navigation research needed an antenna that could turn a hexacopter into a simulated LEO satellite. We customised the IceConeFeed for 2490 MHz S-band, validated it on the Antenna Test Facility, and flew it.
L-Band Helix Antenna for Radio Astronomy – A Practical Guide
Radio astronomy opens a window to the universe by capturing radio waves emitted by celestial objects. Recently, I had the pleasure of discussing a successful H1 antenna setup with Huub, an enthusiast who has been experimenting with various configurations to optimize his radio astronomy observations. In this post, I will share insights from our exchange,…
IceConeFeed Right Hand Circular!
The nominal QO100 uplink which is using a dish reflector requires a left hand circular polarized (LHCP) feed. This is because the dish reflection mirrors the polarization and turns it from left to right hand as the satellite expects it. But what if you have a dual reflector like OH2JKU in Finnland? You need to…

United Nations on QO100 / 4U100QO
From May 18-20 dx-adventure will be QRV on #QO100 from the roof top of the #UnitedNations in #Vienna using #4U100QO. We have donated #IceConeFeed antennas which will later be handed over to the United Nations Amateur Radio Contest DX Club (ARCDXC). Ready for #QSO? Image are courtesy and copyright of dx-adventure. Want one? The IceConeFeed…
Satellite Dish Modification
On rare occasions the IceConeFeed does not have enough mechanical clearance to be mounted on a specific dish arm. In order to check mechanical compatibility upfront you can use the 2D template and the procedure explained here. Paulo, F5VMJ, demonstrates on how to modify the dish arm to make enough room for mounting the IceConeFeed…
IceConeFeed TX Performance
Dieter DC6EH from Kempen conducted a direct performance comparision of the IceConeFeed v2.0 vs v2.1. A continuous 1750Hz tone in USB was sent on 10498.960 MHz. He used the WebSDR http://websdr.is0grb.it:8901 for SNR measurements. Station setup was a 85cm Fuba sat dish. As shown by the spectrum below v2.1 features almost the same transmission performance…
Schulkontakt Antarktis mit IceConeFeed v2.1
Am 22.03.2023 ging die Schulstation DL0CFG der Carl-Friedrich-Gauß-Schule in Friedland OT Groß Schneen QRV mit der Neumeyer Station III in der Antarktis und zeitgleich der Polarstern über QO100. Die Station war mit einem neuen IceConeFeed v2.1 von uns gesponsert worden. Dazu schreibt Frank, DL5AAR: Vielen Dank für die Überlassung der neuen Version deiner IceConeFeed. Wir…
