[TenTec] Gain antennas

[Able2fly at aol.com]

Yes, certain antennas do have gain. But for gain in one direction there  must 
be attenuation in other directions. Bear that in mind when installing that  
fixed "gain" antenna. You could wind up with a null on a desired path... I  
"upgraded" from a 20m dipole to a 20m EDZ and suddenly could barely work Florida  
stations that were previously strong. But northwestern stations that  were 
seldom herd before, were now plentiful on 20. The EDZ came down in the wind  the 
other day and was replaced with a 80 ft or so wire-in-the-trees. Not  the 
greatest, but Florida is back once again...
