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? Ralph 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? Jerry 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? Ralph 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. Jerry |
