I have the WMR200 also. It looks impressive, mounted on the exterior of my shop, but that's about it. I have found that I cannot receive a signal at the display unit, which is inside the shop, a distance of less than 60' away.

BUT....my shop is metal sided inside and out. Cell phones won't work inside the building either, and my verizon wireless internet requires an external antennae to function...and I can see the cell tower line-of-sight, less than 1/2 mile away.

I've moved the transmitting station for the Oregon unit three times now, but no good...too much signal interference from the metal siding.

"Forget pounds and ounces, I'm figuring displacement!"

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
