Performed simulations and analytical modeling on three antenna types:

1. a half-wave dipole
2. a 110 cm single loop
3. the dual parallel loop (my design)

The results show that:

• the Dual Loop has 3× the radiation resistance of a single loop
• efficiency reaches ≈85%
• gain at 14 MHz is +0.8 to +1.0 dBi (vs. 0 dBi for the single loop)
• performance approaches the dipole, which reaches about +2 dBi

A remarkable outcome, especially given how compact the loop is.
