Reach RS4 & RS4 Pro UHF Antenna (410-470 MHz)

Let's be honest: you're only reading this because you left your original antenna on the roof of a site cabin, or a digger backed over it. After 10 years of supplying commercial RTK GNSS receivers and surveying equipment to the UK, we know the drill. This genuine replacement Reach RS4 & 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.

Why You Want It

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.

FAQ

Can I use this Reach RS4 UHF Antenna on the 868/915 MHz LoRa frequency?

Absolutely not. This antenna is tuned exclusively to receive and transmit corrections via the built-in 410-470 MHz UHF radio. Trying to force it into a LoRa configuration will result in zero communication, endless frustration, and a deeply disappointing day on site.

Disclaimer

We are not legally responsible for missed deadlines because you ordered a UHF antenna when your base station is actually transmitting on LoRa. Double-check your radio frequencies before purchasing, or enjoy pacing around the site wondering why your equipment refuses to talk to each other.
