Martin Ehrenfried G8JNJ has developed an omni-directional antenna with a claimed bandwidth of 2-30 MHz at less than 2.5:1 SWR.  View the TC2M site at the construction article at

This antenna appears to be a kind of “cage” antenna (minus the other half) often seen in broadband 80 meter dipoles.  There are a few AM broadcast antennas that employ a variant of this antenna, such as the folded monopole antenna.  At one time Barker & Williamson made something called a TFTD antenna that closely resembled a folded dipole. This antenna was used by the U.S. military to give broadband HF coverage. Martin’s (G8JNJ) TC2M looks fairly simple to make and gives a reported 2.5:1 SWR from 2 to 30 MHz.  This antenna looks interesting.  It might be worth the time to make one.
