[SixClub] 6 meter vertical

Sun, 29 Feb 2004 20:28:30 -0600

Full size (and some shortened) verticals are best for DX IF the ground 
place is sufficient and the surrouding area is somewhat clear....A 
Vertical will outperform a yagi to a certain point..once the yagi is so 
many wavelengths above ground (this VARIES due to freq...it is 
WAVELENGTHs, not feet or meters :), it wins hands down....

I have used verticals many times on HF....a 1/4 wl vertical WILL 
outperform a horiz dipole that is less than a 1/4wl above ground....that 
is well known
