Yes, phased verticals will outperform a dipole. Some phased verticals will outperform a dipole, depending upon how one defines "outperform". A dipole at a decent height can have a 7 dB gain over a 1/4 WL monopole. A two-element phased vertical cannot equal that figure over average ground. Reference: Fig 10, Chapter 8, The ARRL Antenna Book, 15th edition. The maximum gain figure for a two-element phased vertical is 4.7 dB over a 1/4 WL monopole. The average is about 3 dB depending on spacing and phasing. That same graphic is Fig 11, Chapter 8, on the ARRL Antenna Book CD, ver 2.0. EZNEC sez my simple 130 ft. dipole at 40 ft. has a gain of 10.8 dBi on 10m with a take-off-angle of 12 degrees. It would take quite a vertical array to equal that. (Then I would have to somehow overcome a +10 dB vertically polarized noise level. :-) -- 73, Cecil http://www.qsl.net/w5dxp -----= 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! =----- |
