Re: Topband: K2AVQ FCP antenna

[Joe Galicic]

Richard,

  The FCP is very sensitive to any variations from it’s design specifications.  
You would do well to keep it at least 8 feet off the ground from the bottom 
wire.  Also keep it away from ANY dielectric materials such as wood, wooden 
fences, trees, etc.  

The aerial wire must also be installed as far away from dielectric materials.

I have mine mounted eight feet above ground with 6 inch plastic standoffs 
attached to wooden 2x4 supports.  This is a compromise installation.

It made a big difference when I added the 6 inch standoffs.  I should use PVC 
supports.  I also have a wooden fence right below my FCP.  Nothing I can do 
about that.

When installed properly the FCP will work much better than a compromised ground 
radial system on a small lot.

The FCP made a big difference for me on 160 meters !

The usual solution is to do your best.  I am fortunate that I can erect the FCP 
at 3m away from bushes and trees, but I doubt if I would notice a drop of a few 
feet other than tuning.

Richard,

Go to the Master’s lair and see what he has written.  Click on "Placing an FCP” 
in the left frame.

Topband: K2AVQ FCP antenna

[Richard McLachlan]

Can anybody who has put one of these up advise me?

The original article specifies a counterpoise height above ground of 8 feet. I 
am going to try one but it would be much better in the intended location if the 
lowest wire was at 6 feet rather than 8. Has anybody experimented with a lower 
height and if so was the performance much degraded? Other than that I am 
following the build instructions to the letter.
