If I use a R52Hn wireless card with a single stream antenna (802.11a) antenna and only connect one of the antenna jacks on the card, do I need to find some sort of attenuator for the second antenna connector?

OR is setting Transmit chains to Chain 0 only enough to shut down the second antenna connector to keep it from putting out RF energy?

Select just Chain0 and everything is allright

Thanks plisken!
