I didn’t have time to test the antenna before our cabin trip, so I took some measurements on-site. The antenna was strung between the upper deck of the cabin and a nearby tree.
The wire I used was 63 feet long, I intended to cut it to length when the antenna was put up. What actually happened was I passed the end of the wire through a plastic dog bone insulator and wrapped it back on itself about a foot, and called it good. The SWR turned out to be so close to perfect, I didn’t make any adjustments.
Here is the performance data:
The performance of this antenna was outstanding. I made multiple contacts using no more than 5 watts. The rigs used were a QRP-Labs QCX, a QRP-Kits Weber Tri-bander, and a 4 states QRP Hilltopper. The contacts were from call areas 1,4,8 and 9. While listening to the band, I heard call signs from all 10 call areas in the continental US, Cuba, France and Germany.
