Dan Andersson wrote: The EH-Antenna is just another small antenna with it's preferred field of application. It's not to be compared with any directional antenna as it's mostly omnidirectional. Also, the EH have to be mounted 1/4 wavelength up to work according to the designers. The EH antenna theory is total rubbish. It is physically impossible to mix an electric field and a magnetic field and generate EM radation. The basic operating premise of the EH antenna is a lie. The EH that receives most of the appraisal is the 160m version. Probably because it's very difficult to have a dipole or longwire up for 160m... so when compared to a 160m dipole 10 meter above ground, the EH outperforms that dipole Nonsense. You won't find a single scientifically made test where an EH antenna outperforms a similar size regular short monopole. On 160 meters EH antennas are typically 10 dB down or more from very poor dipoles. If an EH antenna beats another antenna it is always tracible back to the other antenna being grossly poor. There isn't a single professional evaluation of the EH antenna in the world that has ever shown it to be better than any other antenna the same physical size, and most show it is actually worse. If you polled a large cross section of people about a very poor leader of a country, you'd find a significant percentage claiming the very poor leader was a good leader despite very clear evidence to the contrary. The EH antenna and any other widespread myth is no different. It's all about blind faith and spin rather than facts. Some people just don't care about facts, and prefer to live by faith. The EH antenna will probably go on for years, despite the fact it has been proven over and over to be a fraud. 73 Tom |
