UHF radio transmitter suggestion

[studiodemarchi.net (Massimo De Marchi)]

I have an RS3 that I use as a rover, usually connecting to NTRIP services.
Sometimes I use a RS2 as a base, and the LoRa radio, but sometimes the range is simply not enough.
I would like to add an external UHF transmitter to the RS2 base, and use the RS3 internal radio on the rover.
I see the spec guidelines, but I would like to know if there are some suggested/tested modules?
Thanks in advance,
Massimo

Long Range External UHF 450 MHz Radio Kit Offering

Received an e-mail from E38 Survey Solutions, a reseller of Emlid gear. They are offering a Long Range External UHF 450 MHz Radio Kit for use with Emlid Reach RS2+ and Emlid Reach R3. Seems like it should also work with the RS2 receiver as well I would think. I know in the past there has been questions regarding external radios for use with the Emlid receivers. This Kit includes: External UHF Radio and High Gain Antenna Communication Cable for Reach RS2+ or Reach RS3 Power cable with all…

Reach RS+ tests with external UHF radio (450 MHz)

To collect cm-accurate data in the real-time, you need a reliable correction link between base and rover. With a set of Reach RS+, you can use built-in LoRa radio for RTK communication. This will work well for most applications on distances up to 8km (sometimes even up to 19km). In some cases, you might want to use other connectivity options of Reach RS to set up RTK link. For instance, if you send/receive RTCM3 corrections from RTK GNSS receiver of another manufacturer. With the good Inter…

I would second mark1st.john’s suggestion, we did some range testing with these radios as well to give you an idea of the difference from LoRa at the lowest power setting.

Hi Massimo,

I see the guys already shared some recommendations. From my side, I just wanted to attach a post where you can check the requirements for the radio to work in such a setup.

I’d also like to mention the option of a Base shift. It can come in handy when the baseline becomes too large, and therefore, the base must be moved to a closer location. Here’s our guide about it, too.
