size voltage divider I need for transceiver to spectrum analyzer?

A short antenna on the SA would probalby give enough signal to see what

Either that or a single loop around the co-ax feeding a dummy load.
The SA needs to see about 100mV at 30MHz to stay clear of spuriae.

Tried the loop around the coax, just a prior loop I had made up one time
for RG-8 (this is RG-58 I'm using now). It's not tight around the RG-58
of course, but output stays well within the analyzer limit. However,
harmonics vary depending on where I move the loop. Maybe I should make
a tight single loop around the coax?
