![]() ![]() Avoid using a myriad of patch cords and connectors in the shack. You must take measures to reduce losses to a minimum. With more than 2000 EME QSOs, It’s fair to say that I have more hours on the moon than the astronauts. I have expanded my home station to include a 4M dish for 4 MHz EME. ![]() As of the end of 2018, I have completed WAC, WAS, VUCC and DXCC all on 144 MHz via EME. ![]() There's no point in designing and constructing a 15 dBd Yagi only to loose any acquired gain in the feed lines etc.EME is not a compromise antenna design situation. My 144 MHz EME system grew to two, 16 element cross-pol yagis and 1kw. The most important factor for an EME station using a single Yagi is the physical length representing how long the boom is constructed, how quiet the antenna is designed, raw gain, antenna pattern characteristics and any losses associated with the design.Feedlines need to be short as practical and represent the lowest loss possible. Nor are the 'number' of antenna elements attached to the Yagi itself for that matter. work some of the EME superstations like or and others.Output power is certainly one variable in this equation but even more important are the design considerations of the actual antenna used regardless of output power used.So using a 'single Yagi' isn't the main issue. With 50 watts and a single Yagi you.could. A simple 144 MHz Dual 9-element Yagi setup for EME One of the unique characteristics of EME is that it is possible to hear and observe your own transmissions echoed back approximately 2. ![]()
