OK Gurus...... Quarter-wave L, vertical to 66 feet, balance horizontal. 32 radials on the ground, length ranging from 35 to 68 feet with a good mix of those lengths. Using 14 solid copper, insulated

Most likely ground losses make the impedance high...try adding even if temporary some 1/4 wave radials or lay some large squares of rabbit or chicken wire in all directions to mitigate the lossy grou

Because you measured in the shack. The length of line between the shack and the load is an impedance transformer. Study the material in the ARRL Antenna Book on Smith charts. If you know the complex

Let me second Cliff's sage advice and gild it  a bit......   Get 3/4" or 1" dia L type copper pipe (Home Depot, others) and make three 5 foot ground rods... Drive these into the ground in a triangle
