The DX Commander Classic has the lowest output. https://sites.google.com/view/menuf...ommander-classic-antenna-perform-on-40-metres https://drive.google.com/file/d/18qTta8JRkIsIHTpF0TbhxaO6w1gNXGh6/view?usp=sharing The analysis includes a model for: https://www.qsl.net/4nec2/ Analysis is undertaken with an average ground because that is what most of us have at out QTH. The model can be adjusted and run to estimate variations for your setup. DX Commander 40M on the air Field Test outcome was ZERO contacts to VK / ZL at 19,000 Km distance from Cornwall. https://drive.google.com/file/d/1jwUnN908KRI7oxWPWwnOANgED_z6duIJ/view?usp=sharing CONCLUSIONS: DX Commander Classic has very little DX output performance between 5 degrees to 10 degrees being only -3.7dBi to -7.5dBi Antennas below: have much more signal output above DX Commander Classic of: Vertical dipole +1.8dBi to +2.5dBi + 171% 1/4 wave vertical with raised radials +2.6dBi to +2.8dBi + 191% horizontal dipole + 6.2dBi to +10.0dBi + 200% to 320% DX Commander Classic DOES NOT Command DX signals. DX Commander Classic feed with 100W will only reliably put out: an S1 signal 3,000 km to 5,500 km, an S9 to a distance of 1,200 km, via VOACAP Analysis has only a 3% probability of communicating with VK / ZL. Could be significantly improved by writing an adequate construction manual which explains with the radial system you could put in with the soil system available at your operating location, how much DX performance out put you can actually expect to get.
