The severe hail storm around the Bari area / Italy on Aug 19 destroyed car windows and Ice Cone Feeds like this one. Should this happen to you, please order a replacement radome or re-print one yourself.

IceConeFeed v2 review by TechMindsYT
Check out the review of the #IceConeFeed v2 for #QO100 from @TechMindsYT here: Want one? The IceConeFeed v2.1 is available in the shop — fully assembled and tuned for QO100.
IceConeFeed Review in Italian by IS0DCR
IVAN, IS0DCR, was so kind to do a review of nolle.engineering including QO100 IceConeFeed for all Italian OMs, enjoy:
IceConeFeed Installation Tips
Some stations have quite tight clearances between the Iceconefeed reflector and the LNB arm. To do a fit check before installation you can use a full scale drawing and quickly make a template (2D printer ;-). Note: there are two templates to choose from, see below, for IceConeFeed v2 and DIY. The v2 version features…
3D Patch Update
The 3D printable patch feed for #QO100 is in the making. A design change from the rectanglar to elliptic has been found to be more efficient and achieving a better axial circular polarization. This is a prelimiary current simulation at 2.4Ghz. The direction of rotation will change from RH to LH.
Tors South Norway Rove
Tor (LA9XGA) was on tour DXing from Southern Norway being QRV on various Oscars. His QO100 mobile station is sporting the Ice Cone Feed v2. I took a chance and worked him on QO100 one evening. Images by courtesy of Tor (LA9XGA)
LNB attenuation
By principle the helix antenna will blank out a certain amount of signal as it is mechanically located in front of the receiving element. A geometrical analysis illustrates why and gives a good indication of the attenuation order of magnitude.Assume an opening angle of the LNB of 50 deg. The helix shade from the LNB…
IceConeFeed Thermal Test — 120 W CW
A customer put the IceConeFeed under 120 W CW with a thermal camera. Peak temperature at the feedpoint: 31.6 °C — a ~20 K rise at the worst-case duty cycle.
