For 2 years it's been 4-5 bars. Returning from a week's vacation, it's 0-1 (CINR 1 to 4). No changes here. What's changed at Clear?
Flipping the ext antenna switch to enable then back to disable. fixed the weak signal problem. Iffy switch contact, apparently. Now: RSSI 67, CINR 23. 5 bars (LEDs). This is a Hub Express.
