Priced at $199.95, here are the features:
The sensitivity specifications are as follows:
Sensitivity
<10 mV a 10 Hz- 10 MHz
<20 mV @ 10 MHz- 50 MHz
<0.8 mV @ 100 MHz
<7 mV @ 300 MHz
<6 mV @. 1 GHz
<I00mV @ 2.4 GHz
The supplied telescoping whip is removable, so it's conceivable that a probe could be used in it's place to perform radio alignments.
