This is the antenna I want to copy before I start experimenting: http://hamcall.net/6bandmegpole.html Hi Buck, they don't give exact building information as far as I can tell. Here's what they say: Inverted V with the center at 32 ft and ends at 8 ft. Approximately 135 ft long fed with 100 ft of RG-213. Why 32 ft with the ends at 8 ft? Because that is the configuration that gives the advertised values of SWR. Why 100 ft of RG-213? Because the losses in the coax results in the advertised values of SWR. If you deviate from their configuration including having different ground conditions, you will, no doubt, need an antenna tuner for some bands. They have probably fine tuned their configuration so they can make their claims which you probably will not be able to duplicate. I don't want to discourage your experimentation - just make a prediction based on experience. If you really want an efficient all-eight-HF-band antenna requiring no tuner, you can find one on my web page at http://www.qsl.net/w5dxp/notuner.htm If you don't want to go to the trouble of varying the length of your feedline, you can at least learn what you are up against in your quest. -- 73, Cecil http://www.qsl.net/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 =--- |
