The slot antenna can be made out of any metal surface or plate, with the length of the slot being cut out by a frequency determined in advance. It can be designed and constructed using a discarded TV dish reflector. Believe me when I tell you that it works. In essence, what you have is […]
Yes, one could spend several hundred dollars for the optimum beams, which might extend 100 feet into the horizon. Or, one could expand the idea of a very cheap 26-inch bicycle rim. Admit it, we’ve heard about tuning a bicycle rim and using it. It will definitely go on 10 meters! SWR Antenna Analyzer is […]
