And this part: ? Antenna Efficiency Frequency (MHz) Efficiency (dB) 2 -12.7 3 -8.8 5 -6.4 7.5 -4.8 10 -4.2 20 -2.8 30 -2.1
I'm not sure what a negative antenna efficiency means. Compared to an isotropic source? It is large, and must spend a lot of power heating those resistors.

It's the reference to termination resistors in the SPX data sheet that bothers me.
