Our Ideas & Additional Information
Some good imagery would include radio towers (not necessarily cell towers, more like lattice towers you'd see for traditional radio), signal waves, antennas, two-way radios (either handheld or mobile radios).
A wordmark would also be great as long as it isn't too cartoonish or loud.
Some other ideas would be to look at radio manufacturer logos such as Motorola, Icom, Kenwood, etc for inspiration.
Added an early draft of our website without a logo so you can see the color theme and placement of the branding in the header. We like Google's Material design elements since they are clean and professional.
