We added a new product, An EFHW-7510-2K antenna which has low SWR at 75M (3.9MHz) while maintaining the same characteristics on bands above like 40,20,17M… etc, just like EFHW-8010 model does. For upgrades, we sell 7510 wire assembly in 14 AWG wire too for those who want to just switch the wires on their existing EFHW-8010 antennas. The links are here:
