Don't know what a Cobra is.


It's a linear loaded folding shaped like this for 1/2 of the

antenna:

62 feet per side
---------------------------------------+
|
+--------------------------------------+
|
+----------------------------------------FP--- other side

Freq MHZ Loss relative to ideal
1.9 8 dB


The above antenna doesn't have nearly that amount of loss on 160m.

======================================
Folding is quite beneficial then at 1.9 MHz. How did you find what
the loss actually is? Did you model it? How far apart are the 3
wires?
