Around 24 hours of work went into this antenna.
It has 8 1/2 wave elements with 8 hairpin bend 1/2 wave traps
Below the N-Connector feedpoint is another trap to get rid of any currents
that should not be there.
Here is a picture of the single hairpin trap.
1/2 Inch copper pipe
1/4 inch copper pipe
Yet to try it out, still too much snow on the roof that makes it too dangerous
to be up there. Still -16 here and we had a large dump of snow recently.
