[Skimmertalk] New MFJ omni-directional horizontally polarized antenna

[Bob Wilson, N6TV]

Interesting results.  How high is your horizontal Omni?  Is the 20 ft
vertical ground mounted?  How many radials?  Nearby antennas or towers?
Preamp voltage disconnected automatically when you transmit?

What does "buffered unity gain" mean?  A preamp that varies its gain by
frequency?  How much gain did you program for each band?

Bob,


Good idea about skimmer use.  I am already doing exactly this for my second
CW Skimmer, K3PA-2-#.  I have a pretty close homebrew clone to the MFJ item
(basically a multiband squalo) for 6/10/12/15 M.  Very easy and cheap to
build.


My thought was that my buffered (unity gain) 20 ft. vertical would be
better on 160-40 and a horizontal omni would be better on 6-10-12,
especially with a preamp (I use a PGA103 based board) to complement the
characteristics of my QS1R.  I wasn't sure about 20 and 15.


Early results are that the vertical is much better on 160-20, similar on
15M, and the horizontal omni is better on 12-10-6.  I am now running both
skimmers with 15M covered by both.

At Dayton, MFJ displayed a new 20 through 10m horizontally polarized HF
antenna.  This could be ideal for skimming the high bands, and also for
Faros <http://dxatlas.com/faros/>, if you can get it high enough.  They
claim a TV mast is sufficient.
