Curt Deegan" WWWR@e... wrote: Excellent list, thank you. While you mention two models from LF Engineering, you did not include the M-601C, possibly because it is an AM BCB only active vertical. I have it and the H-800 which you did include, and use them phased together to great advantage on the MW band, for both the directional characteristics achieved and to reduce ambient noise, especially during daytime. There are also the L-400B LF/VLF active vertical, and the L-111 -- which I have -- that combines the L-400B with an up-converter for tuning in the 4.0-4.5MHz range. LF/MF/HF and LF/VLF marine versions are also produced by LFE. Except for the H-900 -- an enhancement to the H-800, both of which are still in production -- all of these active verticals are available directly from LF Engineering. Because of some marketing arrangement, the H-900 while an LFE product, is only available for order through Grove, as well as the H-800 as you mentioned. The LF Engineering web site is at: http://www.lfengineering.com/products.htm (For the record, I am unaffiliated in any way with LF Engineering.) Following hurricane Wilma, I picked up the three LFE verticals from my yard and patio, placed them and the Christmas tree stands on which they are mounted back on the flat roof from which they had been unceremoniously removed, and turned them on, all was back in business without a hitch. I've been very happy with these LFE active verticals, both for their antenna performance and their weather resiliency. Curt W. Curt Deegan Boca Raton, (Southeast) Florida . .

What About - An LF Engineering Vertical Active Antenna + Plus a Slinky Jr. ?
FO&A,
With one of the LF Engineering Vertical Active Antennas sometimes a Slinky Junior (Jr.) can be use with good effect. http://groups.yahoo.com/group/Shortw...a/message/6563 HOW TO : Place the Slinky Jr. over the Antenna Element and Secure the Bottom of the Slinky Jr. to the Bottom of the Antenna. * Two to Three Plastic Wire Ties will do the job. * Attach a piece of Fish Line or Mason Line to the Top of the Slinky Jr. and Rig it to a Higher Object/Structure above the LF Engineering Vertical Active Antenna. - OR - Lay the LF Engineering Vertical Active Antenna on it's Side Horizontal [Flat] and Rig the Slinky Jr. as a Horizontal [Flat] Antenna (Mini-Random-Wire / Micro-Long-Wire). Now - Extend the Top of the Slinky Jr. so that it is Stretched-Out about Four Feet Overall and try your Radio Reception for improvement with the LF Engineering Vertical Active Antenna. Next - Extend the Top of the Slinky Jr. so that it is Stretched-Out about Six Feet Overall and try your Radio Reception for improvement with the LF Engineering Vertical Active Antenna. Continue to Stretch-Out the Slinky Jr. Two Feet at a Time until you notice Signal Overloading and Images with the LF Engineering Vertical Active Antenna. = Four Feet ( 4' ) = Minimum = Six Feet ( 6' ) = Eight Feet ( 8' ) = Ten Feet ( 10' ) = Twelve Feet ( 12' ) = Maximum NOTE - The Slinky Jr. {Junior} which has about 85 Turns with a Diameter of 1 7/8 Inches and a Circumference of 5.89 Inches for a Total Wire Length of "41.7" Feet. * Optimum "Stretched-Out" Length about 13.3 Feet Once Again - Sometimes this works in getting that 'little extra out' of the LF Engineering Vertical Active Antenna; and sometimes it is a case study in Signal Overload using and Active Antenna. try it and see - iane ~ RHF .. .
