After 10 years of supplying commercial RTK GNSS receivers and surveying equipment to the UK, we know the drill. This genuine replacement Reach RS4 \u0026amp; RS4 Pro UHF Antenna ensures your base and rover setup can actually communicate. Tuned strictly for the 410-470 MHz frequency band, it's non-negotiable for transmitting and receiving RTK corrections to maintain that elusive fixed solution. Whether you're dodging freezing rain or dealing with impossible client demands on a remote site without an NTRIP connection, you need your surveying workflow to just function. Buy this so we can comfortably pay our office heating bill, and you can get back to logging points instead of yelling at your tablet.\u003c\/p\u003e\n\n  \u003ch3\u003eKey Highlights\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAbsolute Compatibility:\u003c\/strong\u003e Native plug-and-play fit for the Emlid Reach RS4 and Reach RS4 Pro units.

If your workflow relies on local UHF radio protocols like TRIMTALK rather than cellular network connections, this antenna is the critical lifeline between your hardware. Without it, you are doomed to 'Float' status while the project manager breathes down your neck. It’s built to endure the grim realities of British construction sites—just try your hardest not to lose this one.\u003c\/p\u003e\n\n  \u003ch3\u003eSpecifications\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFrequency Range:\u003c\/strong\u003e 410–470 MHz\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRadio Compatibility:\u003c\/strong\u003e UHF\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDevice Compatibility:\u003c\/strong\u003e Reach RS4, Reach RS4 Pro\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Data unavailable (Emlid kept this a secret, but it weighs exactly as much as a standard antenna you're about to lose again).\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e Data unavailable (Standard issue length.
