Antennas are in free space. Gain curves include conductor and mismatch losses. The gain reference is a halfwave dipole and the backlobe region is the rear half-plane. Models do not include balun loss, which may lower the gain of 300Ω antennas, nor the boom, which may degrade the performance of antennas with phasing lines. The lists order antennas by performance at 98 MHz.
