[TenTec] The Next Flagship

[R. Eric Sluder - W9WLW via TenTec]

KK9V and I came in 1st place for the VE5 section on Field Day back in the very early 90's using that exact antenna Bob.  We operated from a tent with the fan dipole high up in the trees located in Moose Jaw provincial park.  What a great time.  

Its a good antenna config, but the wires are seldom straight and it ain't pretty to a non-ham. :-(  I tried to install that same antenna about 3 years later at the QTH and the XYL wasn't keen on its looks.
