[TowerTalk] OWA antennas

[Cqtestk4xs at aol.com]

It looks like the sale of our KH6 QTH will go through and we  will be 
heading back to Florida.  I would like to do some homebrew OWA  antennas or 
copies of recently designed monobanders for 10, 12, 15, 17, 20 and  30 for the 
new station.
 
Looking at either 6 or 8 el on 10, 6 el on 15, and 5 el on  20.  The 
antenna ideas for 12 and 17 are a little more flexible, but 30  should be a 3 el.
 
Any ideas for dimensions, materials etc?
