Vertical Antennas for 160 Meters / CQ 160 Contest ssb

Team Steve & Steve give an overview two vertical antennas that we use for the CQ 160 ssb Contest. We switched to a vertical design in order to pick up more DX stations. A dipole for 160M is nearly impossible to get high enough for DX. These two really worked well this year for us. Design and measurements below. Steve Ad4xt 1/4 wave elevated vertical: Base was 10' high vertical element 130' 14ga. copper strand insulated wire 5 elevated radials 17 ga. aluminum fence wire at 10' 130' long vertical element goes up 55' then inverted L to a tall tree. EFHW 160M / 80M custom built transformer for 160 / 80 3 core 290 x type 43 mix. 3 turns on the primary wire goes up 60' then inverted L to 85' pine. Both worked very well.
