[OKDXA] K9AY loops

[K5TT]

Hi Kim,

I am using a shunt fed tower on 160m.  Just use a
variable capacitor in series with the shunt.  I vary
the cap for lowest SWR.  I have a 30 foot shunt out
abt 18 inches on a 70 foot tower and the cap is abt
560 pfd's.  Any variable cap will work for testing but
you will need to get something that will handle your
power for operation.
