Description
What it does
The IceConeFeed Customized is a built-to-order variant of the IceConeFeed v2.1. We retune the helix and adjust the turn count to match your application — useful when the standard 2.4 GHz QO100 narrowband configuration does not fit, for example for S-band downlink experiments, drone-borne transmitter mock-ups, indoor-navigation testbeds, or wide-band amateur work outside the QO100 band.
Each unit is hand-built and tuned to your specified parameters. Typical lead time is two to three weeks from order placement.

How to order
After purchase we will get in touch to confirm the exact center frequency (between 2200 MHz and 2500 MHz) and helix turn count (between 2 and 3.5 turns). Once these are agreed we build, tune, and measure the unit before shipping.
Quality control & test campaign
Every unit is tuned to spec before it ships. The acceptance step is an S11 / SWR measurement at the customer-specified center frequency — units only leave the bench once they meet the published tolerance.
For research-grade applications you can pick the Full radiation pattern measurement variant on this page: the unit is run through our Antenna Test Facility before shipping and arrives with a measurement report covering the full 3D radiation pattern, gain, axial ratio, half-power beamwidth, and an S21 sweep across the band. Same measurement campaign as the standalone Radiation Pattern Measurement Add-On, just bundled with the unit.
Reference project
For an example of a customised IceConeFeed in the field, see the Lab post “Drone as Satellite: Custom S-Band IceConeFeed for ESA Indoor Navigation Research” — a 2.49 GHz variant flown under an industrial hexacopter to simulate a low-orbit satellite for an ESA-funded indoor navigation testbed.
Typical use cases
- S-band research telemetry, LEO emulation, indoor navigation testbeds
- Drone-borne transmitter mock-ups
- Wide-band amateur experiments outside QO100 narrowband
- Educational projects that need a specific center frequency
