The bandwidth on the Alexloop.
28.004 (SWR at 2.2) to 28.060 (SWR at 2.1) around 60 Khz of bandwidth.
21.020 (SWR at 2.0) to 21.070 (SWR at 1.7) around 50Khz of bandwidth
14.000 (SWR at 2.1) to 14.035 (SWR at 1.9) around 35Khz of bandwidth
10.110 (SWR at 1.8) to 10.125 (SWR at 1.9) around 15Khz of bandwidth
7.005 (SWR at 2.5) to 7.015 (SWR at 2.6) around 10Khz of bandwidth
I did however use the ATU on the KX3 and the SWR was flat when used on all bands so if I want I can use the tuner and increase the bandwidth of the antenna. I do know that my attic dipole on 10Mhz the SWR is about 9.1 to 1 and the tuner will flatten that out and I have made lots of milli watt contacts all over the world. So the next step is to get this antenna out doors and give it a whirl out there and see how it does.
