That’s right, it isn’t (and has a lossy broadband matching transformer). The MPAS Lite UM claims 1.8 MHz through 54.0 MHz but I use it for 30m to 10m; it’s tolerable on 40m. I like it for its robustness (in high winds), speed of deployment and smaller footprint on busy summits.
Funny you should mention that because I intend to take both antennas and an antenna switch to my target SOTA hill G/LD-058 before the TA S2S event to do a A vs B receive-only comparison specifically for 10m and 15m. I used the LNR EFHW (as a sloper) recently getting US chasers during 25 mins on 10m and 8 mins on 15m with my 10W of CW.
I’ll try it as an inverted-L for the test. G/LD-058 may be the smallest SOTA summit in England but it’s one of the very few in my region that has trees (for the far end of my inverted-L), overlooks the sea to the NW (great circle route to N. America) and the parking is only 10 minutes drive from home.
