Well let me tell you this antenna kicks butt

Feed it with a 1/4 wave matching stub made out of RG11/U

Feeding in the bottom center gives you more Horizontal vs Vertical and the trade off is well worth it as this antenna averages around a S4 to S5 noise level or lower during the 160 Season

Updated: Last year we added a NJ3I  High power 1:1 Isolation transformer between the feed-line and the matching 1/4 75 ohm coax

No time for a G5RV on 160 meters
