Well let me tell you this antenna kicks butt
Feed it with a 1/4 wave matching transformer made out of RG11/U
1/4 wave coax transformer Formula = 251/f in megahertz times the velocity factor of the 75-ohm coax ( Example: 251 divided by 1.9 = 132.1 X .82 = 108.2 feet )
Feeding in the bottom center gives you more Horizontal vs Vertical and the trade-off is well worth it as this antenna averages around an S4 to S5 noise level or lower during the 160 Season
Updated: Last year we added an 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
