Help colinear building problems
 

Im trying to build a 6dB simple colinear for my 2.4g wireless setup.
Im using a simple setup
from:

//martybugs.net/wireless/collinear.cgi

It uses a short piece of 12ga copper house wire with just two one turn
loops at 1/2 wave & 3/4 wave. I have access to a network analyzer @
work so i tried measuring the antenna'but come up with 1.4 g & 3.4 g.
No matter what i do i cant get the antenna near the 2.4 band.
Over the years Ive build many amateur band antennas of all types but
this ones got the best
of me.

Looking at the article, it appears the author did not hook up a
network analyzer to his prototype. How do you know that your network
analyzer connected to his antenna would not yield the same results.
Why not simply test the antenna in its intended application and see how
it does. Whether you are getting 6db gain over a 2.4ghz isotropic
radiator will be hard to test.
If you have built ham band antennas, you know success can be judged
in many different ways.

Hi Marty

Would you be open to trying a different configuration?? This site shows
how to build colinear arrays from lengths of coax
