[Milsurplus] TCS-9 Output matching?

[WA5CAB at cs.com]

The phantom antenna in the TN-233/SRC is 12.5 ohms in series with 100 uuf 
for 3-12 MC (Band 2 & 3) or 12.5 ohms in series with 300 uuf for 1.5-3 MC 
(Band 1).  Presumably 200 uuf would work better between 3 and 4 MC but the 
selector switch only has two positions for the capacitor choice.
