What it does<\/h2>\n

The IceConeFeed v2.1 is the current production version of the QO100 dual feed. It clips onto the LNB of a standard offset satellite dish and lets you transmit on the 2.4 GHz QO100 narrowband uplink without modifying or removing the LNB \u2014 the LNB stays in place and continues to receive the 10.7 GHz downlink. Fully assembled, tuned, and tested before shipping.<\/p>\n

Quality control<\/h2>\n

Every unit is tuned to spec before it ships. The acceptance step on each unit is an S11<\/sub> \/ SWR measurement<\/strong> at the operating frequency \u2014 units only leave the bench once they meet the published tolerance.<\/p>\n

Full 3D radiation-pattern measurements (gain, axial ratio, half-power beamwidth, S21<\/sub> sweeps across band) are part of our development and validation work and are also available as a service on customer-supplied antennas \u2014 see the Antenna Test Facility<\/a>.<\/p>\n

Polarization & dish use<\/h2>\n

This antenna is a dish feed<\/strong> \u2014 it sits in front of a parabolic reflector. Because the dish reflects the signal once and inverts the circular polarization, the feed must be the opposite<\/em> handedness of the desired received signal. The default LHCP fits the QO100 narrowband uplink (which arrives RHCP at the satellite); pick RHCP if your dish has two reflectors (see this example<\/a>).<\/p>\n
