Providing advanced agricultural machinery and equipment at the forefront of innovation, our customers benefit from reduced work stress and increased productivity, resulting in higher yields and sustainable growth and profitability.
The 35W High-Power External Radio is the ultimate signal solution for large-scale precision agriculture. While standard internal radios are limited to 3-5KM, this professional-grade booster extends your RTK correction signal up to a 25KM radius. Engineered for reliability in complex terrains, it ensures your auto-steer system maintains centimeter-level accuracy even in the most remote corners of your farm.
Standard internal 2W radios often suffer from signal dropouts caused by hills, trees, or long distances.
The radio supports two power levels to balance performance and power consumption:
Equipped with advanced digital filtering technology:
Agriculture doesn’t stop for the weather, and neither does this radio.

1.Mounting:Secure the radio on a high point (tripod or rooftop) for maximum range.
2.Connection:Connect the 5-pin serial cable to the RS232 port of your RTK Base Station.
3.Antenna:Attach the high-gain fiberglass antenna to the TNC connector.
4.Power:Connect to a stable 12V power source (battery or tractor power).
5.Channel Sync:Ensure the radio channel matches your Tractor Auto-Steer receiver.
1.Can I use this radio with other brands of RTK base stations?
Yes. As long as the base station supports RS232 output and the receiver operates within the 410-470MHz frequency, it is generally compatible.
2.How far can the signal really go?
While the maximum range is 25KM, actual distance depends on antenna height and terrain. Higher antenna placement always yields better results.
3.Does it need a monthly subscription?
No. This is a one-time hardware investment. You own the signal, meaning zero annual fees compared to NTRIP/CORS networks.
4.Is it safe to leave outside in the rain?
Absolutely. With an IP67 rating, it is designed to be left outdoors in harsh weather conditions.
Don’t let poor signal slow down your farm’s productivity. Enhance your RTK system with the 35W High-Power External Radio and enjoy 2.5cm precision across every acre.
