- All, This journey started several months ago with the purchase on an 8405a to measure an antenna. One of the items listed at that time was a bi-directional coupler. Finally I have found one and am be

- Hi Dan, A bi-directional coupler has a mainline input and mainline output. The other two ports are the coupled ports. One is zero degrees phase shift and the other is 180 degrees phase shift because

- Thank you. The coupler I have is too high frequency for my current needs. I am interested in a 1 to 100 MHz bi-directional coupler. However bi-directional couplers are much less common then uni-direc

- Yes, the mainline can be fed in either direction. For a single port 10db coupler the coupled port will be 10db down. If you feed it backwards the coupled port will now be isolated. If you take two of
