[TowerTalk] re Radials

[hasan schiers]

Bill,

If you don't understand the fascination, then you are not a DX chaser on 
those bands, in which case you have no use for a vertical (other than 
convenience or quick temp setup)

If you seriously chase DX on 80 and 160m, a low angle radiator on tx is 
essential. In the vast majority of the cases, the only way to get it is with 
vertical polarization. Having run low dipoles on all 3 bands, and having run 
verticals on 80 and 40 with good ground systems, I can say with some 
certainty that the verticals outperformed the dipoles dramatically for DX.

A DX chaser doesn't care about local signals...in fact we would rather be 
rid of them entirely <vbg>

And none of the studies I am seeing reflect high angle arrival of dx signals 
on 80/160. Higher than on 20m and above yes, high enough for a low dipole to 
be competitive, absolutely not.

If one only wants local coverage and space is available, a simple dipole is 
often the best choice. Then again, that wasn't the poster's question.

More to the point, however, is that the original person with the question 
asked how to do the vertical's radials and wanted an explanation of 
conflicting advice he had gotten/seen. I was trying to help him understand 
"how things work"....a precious commodity among amateurs these days.

73,
