I'm building a turnstile in the 1GHz range. The length of the coax
for the 90* phasing loop is too short to work with easily. Would I
get the same results using a phasing loop 270* in length?

Hi Ralph

Could you consider constructing your Turnstile so the "phasing loop" is
a
straight length of coax, about 2 inches long seperating the two (crossed)
dipoles?

I figured 1.8 inches for 1066 MHz. I wanted to build it into a pvc
pipe cap so there isn't much room to work. Also, am I correct to
assume the 1.8 is the total length, including what is stripped back to
make the connection?

Hi Ralph

I dont know what your needs are for this Turnstile antenna, so my input
may be of no value. But, a Turnstile can be made to work by feeding both
dipoles with one feed point. No phasing harness is needed. Make one
dipole a little short so it is capacitive and the other dipole a little long
so it is inducvtive.
