S ? and WHY ? in search of the one-best answer . . . ~ RHF *. *.- Hide quoted text - - Show quoted text - Though I have not been living on the West coast, nevertheless one cannot expect strong signals from certain areas over there . In dealing with such unstable propagation as we had in the last few years a single antenna may not be sufficient and re-orienting it may not be enough. Over here,in NYC I tried using a commercially made sloper antenna in the early 90's and didn't see it performing substantially better than a simple random length wire. That applies only to my location,that is. . . The best antenna I EVER had was a home-made T2FD. Much quieter,had some gain and it was absolutely omnidirectional as far as I know. It used a 9:1 balun transformer from Palomar (sadly they stopped making it). Reception was outstanding,considering the RFI and other man-made noise omnipresent over here. |
