I agree. To make the MFJ more versitile, add 2 velcrow straps at the top and
bottom to secure it to the boom or mast. It leaves your hands free. I add a
sheet of rubber on the back to keep it from slipping.
I have also replaced the 50 ohm resistor in the Wheatstone bridge with a 75
ohm resistor for 75 ohm cables. 75 ohm cable is still widely used so why not
a analyzer for it? I have 75 ohm applications. I installed short terminal
posts for the resistors for easy exchange. It is a job to do this however.
Another problem is the gaps between the copper circuit board are very close
and solder bridges occur real easy.
I'd like to see a MFJ 50/75 ohm model and have recommened this to Martin F
