We were cleared for the visual approach to runway 26 in JAX. We descended to 1600 to intercept the FAF (Final Approach Fix). About 2 miles out from the FAF; we got a G/S* (Glideslope). I followed the glideslope; and just around 1000 ft we got the altitude warning from ATC. I corrected my descent and continued to a visual approach with the VASI (Visual Approach Slope Indicator). I believe we received an erroneous glideslope indication. I was fixated on the glideslope and although I had visual contact with the runway; I couldn't tell we were low until we were coming straight in.
We were cleared for a visual approach to Runway 26 in JAX. We were on a right dogleg to final and proceeded direct DALTN which is the LOM (Locator Outer Marker) and set in 1600' (minimum GS capture altitude) in the altitude window and armed APPR. About 2 miles outside of DALTN the glideslope captured and the pilot flying began to descend with it. As we were descending and still on the dogleg at about 950' Tower gave us an ATC low altitude alert. The descent was stopped and we climbed back to about 1200 feet and rejoined the visual PAPI (Precision Approach Path Indicator) and landed. It appears we captured and followed a false glideslope.
Air carrier flight crew reported receiving a low altitude alert while descending on a false glideslope into JAX.
