Even better without the short coax.
Need to replace the S0239 socket with an N-Type and use a straight SMA to N-Type to the dummy load to improve it I think.
This is from 10kHz to 900MHz, considering it's going through an SO239 socket, PL259 plug, BNC socket, BNC plug, SMA socket, SMA plug, another SMA plug and finally another SMA socket, I don't think it's doing too bad really ..
