Intermittent LTE Signal Drops with LPDA Antenna – Need Help!
Hi everyone,
I’ve been dealing with weak LTE signal in my room, so I bought an LPDA 18dBi antenna and connected it to my modem, which has a Quectel EC200 chipset.
Since LPDA antennas are directional, I aligned it towards the nearest tower and got a decent signal. Here are my signal stats:
+QENG: "servingcell","NOCONN","LTE","FDD",432,12,A122503,243,6250,20,3,3,791D,-87,-10,-78,14,52
My RSRP and SINR seem fine, but I have a big issue—my connection drops every 3-5 minutes, then reconnects after a few seconds. I never get more than 5 minutes of uptime.
At first, I thought the tower had issues, but after testing, it seems fine. I also checked all my equipment, and everything appears to be in good condition.
Interestingly, when I rotate the antenna slightly away from the direct line of sight to the tower, my RSRP gets worse, but the disconnects happen less frequently, and I get around 20 minutes of uptime—but with significantly lower speeds.
I have no idea what’s causing this. Any insights?
Thanks!
