What characteristics would a 1/2 wave dipole have if one side was near vertical, and the other side buried along the ground? Would it act like a poorly counterpoised groundplane vertical, or something else? Any redeeming qualities? When two radials are 180 degrees apart and elevated, they tend to cancel the radiation from each other. When you bury one radial, you ensure that ~half your RF energy is lost. If you bury that one radial vertically, you do indeed lose half your signal since you have put half of your dipole underground. Ground mounted verticals give up approximately half their power to ground losses. Then they give up approximately another 3 dB to a rotatable dipole. Approximately 10 ohms of the feedpoint impedance for mobile antennas is ground losses. (Please note that everything I said is approximate. :-) -- 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 =--- |
