@bluejedi yes tested. If you look at the range mapping on the map, I added the HPD13A plot too. 4-layer board compared to 2-layer boards of RFM95W and NiceRF SX1276-C1. Surprisingly more or less same range achieved but not sure about other aspect like EMI performance and how much easier to obtain FCC/CE with the shield.
