In article , Channel Jumper wrote: Ringo's are nothing more then a over glorified dummy load.. I am sure Dr Reynolds of the University of Washington School of Electrical Engineering, who designed that antenna for AEA, would take considerable disagreement, with the above. This design was Extensively Tested on the UofW's Antenna Range, up on Pigeon Hill, West Seattle, Washington, which was donated to the UoW, after the Army was finished with the old Army Communications System site, post WWII. Not AEA, but for Cushcraft. Obituary: http://community.seattletimes.nwsource.com/archive/?date=19920205&slug=1474034 I don't believe Dr Reynolds designed the Ringo Ranger for Cushcraft (Now MFJ). The MFJ catalog page claims the Ringo Ranger II was designed by Lester A. Cushman, W1BX(sk) http://www.cushcraftamateur.com/Product.php?productid=AR-2 Dr Reynolds did write an article "The 5/8-Wavelength Antenna Mystique" for the ARRL Antenna Compendium, Volume 1 Pg 101-106, (that seems to have disappeared from my shelf), which may have created some confusion. My take on the Ringo Ranger is that it's a tolerable design, but not the way it's being built. I've seen far too many cracked SO-239 like connectors, corroded adjustment screws and elements, crumbling insulators, crushed mounting tubes, etc. It's major advantage is that without a molded base transformer, this 5/8 wave or (0.64 wave) antenna can be cheaply built, and that tunes a tolerable wide frequency range. Were it built mechanically better, I'm sure it would have had a better reputation. That lack of a commercial equivalent also offers a clue as to its quality. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
