Topband: T vert feed

[Roy]

'Twas stated:

"Feedline coax shield 1.7 ohms.

The single 1.7 ohms lowers the voltage and even in this case of what
appears to be an excellent ground radials system, the coax will carry HALF
the counterpoise current and waste most of that power, besides being a 
link...(etc.)"


Whaaat???

Where did that 1.7 ohm figure come from....space?

The size (gauge) of radial wires has very little effect on their 
effectiveness as radials, according everything I've ever read. Also, 
effective resistance to ground, due to such intimate coupling to earth when 
radials are at the surface or buried, evens out their equivalent resistances 
and reactances, rendering them "un-tuned." Not comparable to elevated 
radials at all. Voltage and current nodes on surface or  buried radials are 
smoothed and averaged out rendering them un-problematic.

If no balun, including a choke-type, is used at the feedpoint of a vertical 
then the coax braid simply counts as another radial, averaged in with the 
many. Ferrites at the shack end can attenuate any residual RF on the braid 
if it is troublesome there (unlikely).
