Today I've got my self a used Hy-Gain 14AVQ vertical antenna. It's a four band trapped vertical for 10m, 15m, 20m and 40m. I'm not sure if a trap vertical is the best choice for QRP operations but it was so cheap I decided to try it.
I plan to test it from our cabin in the upcoming IARU HF World Championship. Will be back with a report from the contest.
