After putting up the 5+5 element YU7EF 6/4 metre dual band antenna, I was curious how the new antenna performs. Although I realise that a real measurement requires quite a bit of effort, a simple comparison between the new antenna and an antenna with a more or less known performance at least gives a clue… Continue reading »

Dual band antennas are attractive, because of lesser wind load and also because it leaves some room for other antennas. Another aspect was that… Continue reading »
In my humble opinion, Joe Taylor, K1JT, is a true innovator for the amateur service. As a scientist, Joe received several notable awards. The amateur community should be grateful for his efforts and resulting advancement. Many amateurs may forget that our use of frequency spectrum is justified by experiments, with possible spin-off that benefits everyone…. Continue reading »
