Building 12-meter Traps for a 12/17-meter Trap Dipole

摘要

Last month I showed how to build simple and cheap 35-pF high-voltage capacitors suitable for use in 12-meter antenna traps for a 12/17-meter rotatable dipole. Why a 12/17-meter rotatable dipole? Well, I have a Hy-Gain AV-6160 43-foot vertical that works great for me on 160-20 meters. I also have a Hy-Gain TH-1 rotatable dipole for 20/15/10/6 meters, as a dipole at a reasonable height generally outperforms a vertical on the higher bands. Therefore, I wanted a 12/17-meter self-supporting rotatable dipole for best performance on these two bands as well.
