Review on 📶 Bingfu 4G LTE 7dBi Magnetic Base MIMO SMA Male Antenna (2-Pack) - Boost Your 4G LTE Wireless Network Signal with this Compatible Antenna Bundle! by Ricardo Knight

Bought for my LTE modem, I work on the 40/41 band, in the description this antenna will work on the following frequencies Range: 698-960 MHz , 1710 -2170MHz, 2300-2700MHz; so it happened that the length of the average frequency is the same for them; 36.18mm (half wavelength = hwl 18mm) 15.46mm (7.7 hwl) and 12mm (6mm hwl) the height of the entire element does not match the wavelength, the size of the top does not match either. The advantage is that it can be shortened to the desired length from 1/2 to 1/4. because he is bigger. The top element is an aluminum flange, which I don't think does anything, and neither does the spool. I could use the base and pierce through to remove the entire element and use a bike spoke to build the element to the desired length.
