I finally got mine set up yesterday after work; same hardware as you used, right down to the M to M sma. The only differences, I set my antenna under the desk where the Mac Tower is, straddling the UPS and used a 2 meter coax. I have 7 OSI sensors; 3 Radio Shack Temp only (return air, AC Duct, and freezer), windspeed/direction, Outside temp/humidity, and 2 rain senders (mine and a stopped up one somewhere at the neighbors... I only created a device for it because the RFX complained about unknown sensor if I didn't). My results kind of match yours; using the black stick, signal strengths in order were 5,5,4,6,6,5,5... with 2 or 3 dropouts per day on either the return air and/or freezer (I set up a schedule to check every minute and increment a counter any time the last data from any sensor was more than 5 minutes old). after about 12 hours on the new antenna, the signals are 6,5,6,7,5,5,6. The return air, freezer, wind, and neighbors rain bucket got stronger, my outdoor temperature got weaker, and the AC Duct and my rain gage showed no change, and I have had no dropouts. We'll have to see how many there are when I get home tonight... or over the next week or so.
