Frequently Asked Questions
1. Is this radar "Instant-On"?
Yes. Because it is Solid-State, there is no magnetron to warm up, providing full radar imagery the second you turn on your system.
2. Why choose the 6ft array over the 4ft?
The 6ft antenna offers a narrower beamwidth (1.25° vs 1.8°), which provides significantly better target separation and finer detail at long ranges.
