What it does
A 10-turn RHCP helix tuned across the lower GNSS L-band — covering GPS L5 at 1176.45 MHz and GPS L2 at 1227.6 MHz. Suitable for civilian dual-frequency GPS monitoring, jamming/spoofing research, and indoor-navigation testbeds where a directional helix is preferred over a patch.

Color options
The Color option applies to the 3D-printed parts only — the baseplate and rim. The radome pipe is always white, regardless of the Color choice.
- Orange/White — orange baseplate and rim with the standard white radome pipe.
- Custom — custom color for the baseplate and rim. White is a valid choice; pick Custom if you want a uniform white antenna.
