The TEV-1SK is an 8.5 metre vertical radiator, with a 4:1 Unun and the popular mounting bracket BalBrack Kit supplied.
The TEV-1 is made of 6 x 1500mm sections of drawn Aluminium tube.All stainless steel hardware and rugged aluminium construction guarantee long life and trouble-free operation.
The broadband, current style unun is encased in a glass reinforced nylon box,It can be mounted at ground level or elevated to any height above ground or a roof.The antenna is all predrilled and by following the instructions, you will find that the antenna system is simple to assemble and easy to mount.Many options can be utilized for feeding this antenna.
I have done some tests both ground mounted with radials and using the shed as an earth. I find it more resonant and easier to tune with the unun, than with a balun.
Also, pitted against my 80 dipole, it is more resonant and performs better on all bands except 80m(I accept that as it is a bit short).
