For this test coming up, I really want to get both my Spectracom devices, 8164 
and 8170, going at the same time, if only to see that they both go crazy exactly 
on time, yet I'm too lazy to install the second 8206 antenna in a decent 
location.  Do I need a power splitter to do this?  Over at 
http://www.febo.com/time-freq/wwvb/sig-strength/spectracom-antenna.html John 
says he just used a BNC tee and a DC block.  Did he get an even balance?  Close 
enough?  Is there not enough power in a receiver system to make a difference?

I realize the AGC will be open-loop in one of them.  Big deal?  I will lose at 
least 3dB on each.  Can I afford to?  My reception has been lousy lately, 
unlocking during the day when it used to power straight through, even after I 
moved my 8206 to a much better, outdoor location.  But so has the monitoring 
station's in LaCrosse, which is not far from here.
