Hi,

Anybody know about the electrical length of the coaxial adaptors, for
example the N adaptor (m/m, m/f, f/f).
what is the formula? how to calculated?


Ask this question in: rec.radio.amateur.antenna

N connectors maintain impedance, So maybe its just the physical length of
the adaptor. I'm not sure how it might effect the velocity factor.
