U-band 435 MHz Helix for Satellite Uplink
Helix for satellite uplink a 12-turn helix for about an 8' 2-1/2m
Helix antenna design and construction details
Design frequency MHz, Number of turns, Turn spacing, wavelengths
Helix antenne
We decided to put it to the test and build a PVC helix for a 'too high' frequency. Then we wanted to redetermine the center frequency. 2430 MHz is approximately 67% of 3620 MHz. So that will be the design frequency that we give to HelixCalc
