Thanks, That's what I was looking for. so I can use the antenna with 1/4 - 3/4 or center loaded. Note that is 1/4WL which is 1/6 distance (16.67%) from the ends. It is *NOT* 1/4 of the antenna. Hint: There are six 1/4WLs in a 3/2WL antenna. Would the off-center setting create another resonant frequency for the antenna? Nothing changes much. The radiation pattern will favor the long side of the antenna. Since the currents are unbalanced there may be an abundance of feedline radiation. -- 73, Cecil, W5DXP ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= East/West-Coast Server Farms - Total Privacy via Encryption =--- |

A 3/2 wave fed at 1/6 or 16.67 % off one end show low fairly Low SWR's
at the follow frequencies if the wire is cut to 3/2 W @ 7 MHz 7MHz , 9.25 mhz, 11.75mhz , 21.25 MHz (about 7:1 into 50 ohms) and 26 MHz .. These are if fed with 50 ohm line. . Cheers 73 Dave kc1di |
