So, a matching transformer is all I need? I have pretty much decided to use 300 ohm twinlead along the rood ridge with a 300/75 ohm matching transformer to connect it to the coax, and more as needed between the coax and radio. Will that honestly work? Thanks, Dave A 300/50 ohm transformer is the most common type for a shortwave folded dipole. You can still use 75-ohm coax to the 50-ohm side of the transformer. There would be a slight impedance mismatch but it's not that important for a receiving antenna. I do not recommend using a 300/75 TV balun for this purpose because it's designed to operate at much higher frequencies than shortwave. Remember that you *must* connect the two wires in the ends of the twinlead together to make a folded dipole. Otherwise the high impedance side of the matching transformer (300-ohms) won't be the right value for the antenna. Finally, don't expect this antenna to be great for all shortwave frequencies and directions. We discussed why this is so in an earlier exchange. -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |
