End-fed or longwire
Technically a true longwire needs to be at least one wavelength long, but Hams commonly call any end-fed wire a longwire or random wire antenna

Antenna End Fed Links →
160 meter end fed
With this length of wire a coil of 11 turns is required, resonating the antenna on 1.950MHz with an SWR of 1.5:1
10 20 40m Endfed antenna
It's has a large bandwidth with a low SWR and has no radials
40m End Fed Half Wave EFHW Antenna
The feed point of the EFHW is in the order of 3000 to 5000 ohms while the 1/2 wave dipole will be closer to 50 ohms in the inverted V configuration
