I changed my home built Battle Creek Special over to a "tee" for 160 last fall 
and I feel it performs much better on 160 then the "L" of the BCS did. Due to 
yard restrictions the ends of my tee's slope down a bit, one more then the 
other. Overall height is approx 52' with the tee wires extending out from 
there. Had to add a bit of base loading to get a good match.

John,
For DX, the T will be better than the L, especially if part of the L is 
sloping. (Higher radiation resistance.) Also, if the two loading wires are 
the same length, the antenna will be good on 3.5 and 7 MHz. Regarding the 
radials, it all depends on how many and how long you have now, but the T 
will be better for DX, in any case.

73 and GL,
George,
