I have been given 300mtrs of 93 ohm coax.Can this be used in pair to give
46
ohms? Thankyou, David ZL2DG

Yep, just like paralleling resistors. I used to run two parallel RG-59 feed
lines to my 1/4-wave verticals. It matched the vertical impendence very
nicely, and the amplifier's PI network tuning could handle 36-ohm load OK.
