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.

Default 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
