Standing wave ratios on ordinary 1/2-wave dipoles can soar as high as 10-to-1. With all the fuss made about excessive SWR everywhere else, why is it the guru's never mention it, let alone show anxiety about it? What are they trying to cover up? It's a communist plot! ;-) Actually, if your feedline is low loss, and is able to handle the higher voltages you'd get with high SWRs, and you're using a narrowband mode like voice SSB, and your rig can tune load into it, high SWR is not a problem. BTW, if you're using coax to feed a dipole, be sure to make a coil of the coax feedline of several turns at the antenna feedpoint. The object of this is to keep RF currents from traveling down the *OUTSIDE* of the coax shield. Otherwise your antenna's radiation pattern will be goofed up, and also the SWR will get even worse. This also keeps stray RF out of the shack. |
