This is a new antenna from Van Gorden, just pay £59.95, for  a 204ft long all band dipole, covering from 160m - 10m, without any lossy traps or coils. The impedance at the end of the 450 ohm feedline is approx 50-60ohms.

The antenna comes completely assembled and is ready for installation at your location. Before unwinding the elements, decide where you are going to suspend the antenna.Overall length of the antenna is 204ft, so at least 215ft should be available when being installed in a dipole configuration. Less space is required when installing in an inverted V configuration, space actually required depends on circumstances at your location.

On 160m, the electrical centre of the antenna is at about 30ft down the 450 ohm feedline, on other bands it functions on a multiple of wavelength principle. The G5RV-M is slightly short on 160m where the 450 ohm feedline serves as a form of matching stub and/or impedance matching transformer on other bands.
