Is there an available all-in-one antenna to use with the RM520N-GL modem, in order to have both 5G connectivity and GNSS? Do I have to choose between 5G and GNSS on some connectors?
The YEMX425J1A antenna for example does seem to provide 5G but not GNSS.
The use case is about mounting it on a vehicle, hence the all-in-one aspect.
I have found that you just need to check the frequencies the antenna supports. When looking at something like the following:
YEMX425J1A 5G 4-in-1 multiple mount combo external antenna
This antenna has four (4) elements, all of which are exactly identical. You can connect the four leads from the antenna to the SMA connectors (presumably whatever you have the modem card installed in has internal MHF4 (connector on the modem card) to SMA Female pigtails internally) and each of the four (4) antenna connections on the modem card will be able to receive anything within the designated frequencies of the antenna.
If we look at the antenna I listed above it supports:
- Frequency: 410-470MHz, 617-2690MHz, 3300-6000MHz
This means this antenna will support all of the current 5G bands used in North America as well as L1 (1575.42 MHz) and L5 (1227.6 MHz) GNSS signals.
Thank you for the information. The odd thing is that when looking at the detail of the bands for each antenna module inside the YEMC425J1A, it does not talk about L1 or L5 bands or the respective frequencies for GNSS, only the cellular ones:
I guess at some point only testing it will tell if it works
I agree they don’t call out the specific “Bands” that used by L1/L5 GNSS however the frequencies are covered by the antenna elements. I think this is more of a marketing choice rather than a technical one. They seem to be marketing this antenna more specifically to 4G/5G coverage and are not calling out the specifics for the antenna’s ability to cover the L1/L5 GNSS frequencies.

The first tests made confirm that the GNSS signals are received by the antenna. We will make some more tests with concurrent 5G and GNSS but it seems promising. Thank you for the support
