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.
I found some stranded, silver plated #22 wire that has Teflon insulation. It’s not copper-weld, but it’s tough stuff. I attached a 63 foot piece, and wrapped it around the PCB. According to the chart, the wire should be 61’6″, so I will have to trim the antenna for best SWR on site.
Just finished building the kit. The instructions and illustrations were very good and easy to follow. Assembly took less than an hour. I will be using this antenna on our yearly cabin trip coming up in July 2019. I will do some testing before then and publish the results.
