Regarding these tests I've two questions. 1. I would like to try an inverted "cloth hanger" antenna as an alternative to the classic T-antenna (mechanical advantage!) Has somebody already experience with a LF antenna of this kind? 2. I have the means to measure the fieldstrenght (V/m) close to my antenna (up to 100m away). Is there a reliable method to calculate the ERP from the fieldstrenght? 73 de Toni
