[amsat-bb] Avoiding statics on helix antennas

Hello AMSAT list,

I have a problem caused by static electricity building up on my two helix 
antennas (23 cm and 13 cm). Two converters have already been zapped, so I 
have to do something about it.

What measure would you recommend to avaoid statics building up on helix 
antennas?

Does anyone have experience using the shorted quarter-wave-stub mentioned in 
"The ARRL Handbook 2008" pages 23.20-21?
