My take on this problem is,

The low radiation resistance is caused by the antenna been electrically short which also contributes to the high loss resistance,

a lossy loading coil could also be contributing to the high loss resistance,

25ohm radiation resistance + 25ohm total loss resistance gives you the 1:1 vswr & shitty efficiency.
