Steve is in Mexico and wanted to make his own. For the rest of us the best commercial antennas, that do not cost a fortune, and come 'cut' to your specified HAM frequencies, are the Comtelco antennas Paul wrote about.
http://www.comtelcoantennas.com/ http://www.comtelcoantennas.com/PDF%20Datasheets/BS450XL6.pdf I have used a lot of Comtelco antennas with no problems. They are made with brass tubular elements silver soldered in 1/2 wave center fed dipole configurations. Lisa at Comtelco will 'cut' an antenna to your frequency, just tell her, "Will sent you".
