@Piersandro This is the 4G antenna i purchased from Amazon UK: https://smile.amazon.co.uk/gp/product/B07Y1N9ZTF/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 CheerZ

@Piersandro I only had 50% signal strength using the standard antennas and now 75% signal strength. I found the best signal strength by accident when the antenna was horizontal

@kLumpat Just had the issue that you mentioned Been rock solid for a couple of weeks and the last couple of days about lunchtime the bands swap over somehow. Normally bands '1,20' indicated in status...

@Techcareuk I don't think there is anything stopping you removing one antenna and then viewing the signal strength for the remaining antenna. Then repeat for the other antenna? that might work? CheerZ

(Update) Please use the table below when viewing your signal strength under the 'Advanced' tab: RSRP(dBM) RSRQ(dB) SNR(dB) (RF Conditions) Excellent >=-80 >=-10 >=20 (RF Conditions) Good -80 to -90...
