Tnx, Dom for that info.

I received a number of requests for quadfilar information, again.

and see the five files starting with the pic Quad2.4gigs

Be very precise with the measurements, particularly on the 435...
I scaled it from the 2 meter, made a slight measuring error on the 
driven filar, shortened it by 1/4" and the swr went from 3 to 1 to 1.6 to 1....

And use the BEST "N" connectors and coax that you can find, the most 
expensive part of the antenna....
