What method did you use to determin the frequency range of the rubber
duck
antennas ? I have several around here and may give it a try to see what
mine are.

Forgive me for inserting myself here. I just wanted to ask what equipment
you might have for making the measurements?


For starters a HP 8924C ( service monitor with tracking generator) , return
loss bridge, wattmeters.

Better than my stuff. Envy occurs here.

I have an HP vector voltmeter, a Fluke 6061A source, and a few
accessories. It can be a pain to set up some measurements.

I just have not tried the rubber duck antennas to see what frequency I think
they may be for.

Me neither. Might a be fun diversion, but my bet is that we can trust
Helmut's input on this.
